+ An `Ember.Binding` connects the properties of two objects so that whenever
+ the value of one property changes, the other property will be changed also.
+
+ ## Automatic Creation of Bindings with `/^*Binding/`-named Properties
+
+ You do not usually create Binding objects directly but instead describe
+ bindings in your class or object definition using automatic binding
+ detection.
+
+ Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
+ instances. The value of this property should be a string representing a path
+ to another object or a custom binding instanced created using Binding helpers
+ (see "Customizing Your Bindings"):
+
+ ```
+ valueBinding: "MyApp.someController.title"
+ ```
+
+ This will create a binding from `MyApp.someController.title` to the `value`
+ property of your object instance automatically. Now the two values will be
+ kept in sync.
+
+ ## One Way Bindings
+
+ One especially useful binding customization you can use is the `oneWay()`
+ helper. This helper tells Ember that you are only interested in
+ receiving changes on the object you are binding from. For example, if you
+ are binding to a preference and you want to be notified if the preference
+ has changed, but your object will not be changing the preference itself, you
+ could do:
+
+ ```
+ bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
+ ```
+
+ This way if the value of `MyApp.preferencesController.bigTitles` changes the
+ `bigTitles` property of your object will change also. However, if you
+ change the value of your `bigTitles` property, it will not update the
+ `preferencesController`.
+
+ One way bindings are almost twice as fast to setup and twice as fast to
+ execute because the binding only has to worry about changes to one side.
+
+ You should consider using one way bindings anytime you have an object that
+ may be created frequently and you do not intend to change a property; only
+ to monitor it for changes. (such as in the example above).
+
+ ## Adding Bindings Manually
+
+ All of the examples above show you how to configure a custom binding, but the
+ result of these customizations will be a binding template, not a fully active
+ Binding instance. The binding will actually become active only when you
+ instantiate the object the binding belongs to. It is useful however, to
+ understand what actually happens when the binding is activated.
+
+ For a binding to function it must have at least a `from` property and a `to`
+ property. The `from` property path points to the object/key that you want to
+ bind from while the `to` path points to the object/key you want to bind to.
+
+ When you define a custom binding, you are usually describing the property
+ you want to bind from (such as `MyApp.someController.value` in the examples
+ above). When your object is created, it will automatically assign the value
+ you want to bind `to` based on the name of your binding key. In the
+ examples above, during init, Ember objects will effectively call
+ something like this on your binding:
+
+ ```javascript
+ binding = Ember.Binding.from(this.valueBinding).to("value");
+ ```
+
+ This creates a new binding instance based on the template you provide, and
+ sets the to path to the `value` property of the new object. Now that the
+ binding is fully configured with a `from` and a `to`, it simply needs to be
+ connected to become active. This is done through the `connect()` method:
+
+ ```javascript
+ binding.connect(this);
+ ```
+
+ Note that when you connect a binding you pass the object you want it to be
+ connected to. This object will be used as the root for both the from and
+ to side of the binding when inspecting relative paths. This allows the
+ binding to be automatically inherited by subclassed objects as well.
+
+ Now that the binding is connected, it will observe both the from and to side
+ and relay changes.
+
+ If you ever needed to do so (you almost never will, but it is useful to
+ understand this anyway), you could manually create an active binding by
+ using the `Ember.bind()` helper method. (This is the same method used by
+ to setup your bindings on objects):
+
+ ```javascript
+ Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
+ ```
+
+ Both of these code fragments have the same effect as doing the most friendly
+ form of binding creation like so:
+
+ ```javascript
+ MyApp.anotherObject = Ember.Object.create({
+ valueBinding: "MyApp.someController.value",
+
+ // OTHER CODE FOR THIS OBJECT...
+ });
+ ```
+
+ Ember's built in binding creation method makes it easy to automatically
+ create bindings for you. You should always use the highest-level APIs
+ available, even if you understand how it works underneath.

+
+ Many computed properties have dependencies on other properties. For
+ example, in the above example, the `fullName` property depends on
+ `firstName` and `lastName` to determine its value. You can tell Ember

+
+ ```javascript

+ }.property('firstName', 'lastName')
+ });
+ ```
+
+ Make sure you list these dependencies so Ember knows when to update

+ This mixin defines the common interface implemented by enumerable objects
+ in Ember. Most of these methods follow the standard Array iteration
+ API defined up to JavaScript 1.8 (excluding language-specific features that
+ cannot be emulated in older versions of JavaScript).
+
+ This mixin is applied automatically to the Array class on page load, so you
+ can use any of these methods on simple arrays. If Array already implements
+ one of these methods, the mixin will not override them.
+
+ ## Writing Your Own Enumerable
+
+ To make your own custom class enumerable, you need two items:
+
+ 1. You must have a length property. This property should change whenever
+ the number of items in your enumerable object changes. If you using this
+ with an `Ember.Object` subclass, you should be sure to change the length
+ property using `set().`
+
+ 2. If you must implement `nextObject().` See documentation.
+
+ Once you have these two methods implement, apply the `Ember.Enumerable` mixin
+ to your class and you will be able to enumerate the contents of your object
+ like any other collection.
+
+ ## Using Ember Enumeration with Other Libraries
+
+ Many other libraries provide some kind of iterator or enumeration like
+ facility. This is often where the most common API conflicts occur.
+ Ember's API is designed to be as friendly as possible with other
+ libraries by implementing only methods that mostly correspond to the
+ JavaScript 1.8 API.

+ will always begin with 0 and increment monotonically. You don't have to
+ rely on the index value to determine what object to return, but you should
+ always check the value and start from the beginning when you see the
+ requested index is 0.
+
+ The `previousObject` is the object that was returned from the last call
+ to `nextObject` for the current iteration. This is a useful way to
+ manage iteration if you are tracing a linked list, for example.
+
+ Finally the context parameter will always contain a hash you can use as
+ a "scratchpad" to maintain any other state you need in order to iterate
+ properly. The context object is reused and is not reset between
+ iterations so make sure you setup the context with a fresh state whenever
+ the index parameter is 0.
+
+ Generally iterators will continue to call `nextObject` until the index
+ reaches the your current length-1. If you run out of data before this

+ This module implements Observer-friendly Array-like behavior. This mixin is
+ picked up by the Array class as well as other controllers, etc. that want to
+ appear to be arrays.
+
+ Unlike `Ember.Enumerable,` this mixin defines methods specifically for
+ collections that provide index-ordered access to their contents. When you
+ are designing code that needs to accept any kind of Array-like object, you
+ should use these methods instead of Array primitives because these will
+ properly notify observers of changes to the array.
+
+ Although these methods are efficient, they do add a layer of indirection to
+ your application so it is a good idea to use them only when you need the
+ flexibility of using both true JavaScript arrays and "virtual" arrays such
+ as controllers and collections.
+
+ You can use the methods defined in this module to access and modify array
+ contents in a KVO-friendly way. You can also be notified whenever the
+ membership if an array changes by changing the syntax of the property to
+ `.observes('*myProperty.[]')`.
+
+ To support `Ember.Array` in your own class, you must override two
+ primitives to use it: `replace()` and `objectAt()`.
+
+ Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
+ mixin. All `Ember.Array`-like objects are also enumerable.

+ The `Ember.Freezable` mixin implements some basic methods for marking an
+ object as frozen. Once an object is frozen it should be read only. No changes
+ may be made the internal state of the object.
+
+ ## Enforcement
+
+ To fully support freezing in your subclass, you must include this mixin and
+ override any method that might alter any property on the object to instead
+ raise an exception. You can check the state of an object by checking the
+ `isFrozen` property.
+
+ Although future versions of JavaScript may support language-level freezing
+ object objects, that is not the case today. Even if an object is freezable,
+ it is still technically possible to modify the object, even though it could
+ break other parts of your application that do not expect a frozen object to
+ change. It is, therefore, very important that you always respect the
+ `isFrozen` property on all freezable objects.
+
+ ## Example Usage
+
+ The example below shows a simple object that implement the `Ember.Freezable`
+ protocol.
+
+ ```javascript
+ Contact = Ember.Object.extend(Ember.Freezable, {
+ firstName: null,
+ lastName: null,
+
+ // swaps the names
+ swapNames: function() {
+ if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
+ var tmp = this.get('firstName');
+ this.set('firstName', this.get('lastName'));
+ this.set('lastName', tmp);
+ return this;
+ }
+
+ });
+
+ c = Context.create({ firstName: "John", lastName: "Doe" });
+ c.swapNames(); // returns c
+ c.freeze();
+ c.swapNames(); // EXCEPTION
+ ```
+
+ ## Copying
+
+ Usually the `Ember.Freezable` protocol is implemented in cooperation with the
+ `Ember.Copyable` protocol, which defines a `frozenCopy()` method that will
+ return a frozen object, if the object implements this method as well.
+
+ @class Freezable

+ ## Adding Objects
+

+ this method has no effect.

+/**
+ ## Overview
+
+ This mixin provides properties and property observing functionality, core
+ features of the Ember object model.
+
+ Properties and observers allow one object to observe changes to a
+ property on another object. This is one of the fundamental ways that
+ models, controllers and views communicate with each other in an Ember
+ application.
+
+ Any object that has this mixin applied can be used in observer
+ operations. That includes `Ember.Object` and most objects you will
+ interact with as you write your Ember application.
+
+ Note that you will not generally apply this mixin to classes yourself,
+ but you will use the features provided by this module frequently, so it
+ is important to understand how to use it.
+
+ ## Using `get()` and `set()`
+
+ Because of Ember's support for bindings and observers, you will always
+ access properties using the get method, and set properties using the
+ set method. This allows the observing objects to be notified and
+ computed properties to be handled properly.
+
+ More documentation about `get` and `set` are below.
+
+ ## Observing Property Changes
+
+ You typically observe property changes simply by adding the `observes`
+ call to the end of your method declarations in classes that you write.
+ For example:
+
+ ```javascript
+ Ember.Object.create({
+ valueObserver: function() {
+ // Executes whenever the "value" property changes
+ }.observes('value')
+ });
+ ```
+
+ Although this is the most common way to add an observer, this capability
+ is actually built into the `Ember.Object` class on top of two methods
+ defined in this mixin: `addObserver` and `removeObserver`. You can use
+ these two methods to add and remove observers yourself if you need to
+ do so at runtime.
+
+ To add an observer for a property, call:
+
+ ```javascript
+ object.addObserver('propertyKey', targetObject, targetAction)
+ ```
+
+ This will call the `targetAction` method on the `targetObject` to be called
+ whenever the value of the `propertyKey` changes.
+
+ Note that if `propertyKey` is a computed property, the observer will be
+ called when any of the property dependencies are changed, even if the
+ resulting value of the computed property is unchanged. This is necessary
+ because computed properties are not computed until `get` is called.
+
+ @class Observable
+ @namespace Ember
+ @extends Ember.Mixin
+*/
+Ember.Observable = Ember.Mixin.create(/** @scope Ember.Observable.prototype */ {
+
+ /**
+ Retrieves the value of a property from the object.
+
+ This method is usually similar to using `object[keyName]` or `object.keyName`,
+ however it supports both computed properties and the unknownProperty
+ handler.
+
+ Because `get` unifies the syntax for accessing all these kinds
+ of properties, it can make many refactorings easier, such as replacing a
+ simple property with a computed property, or vice versa.
+
+ ### Computed Properties
+
+ Computed properties are methods defined with the `property` modifier
+ declared at the end, such as:
+
+ ```javascript
+ fullName: function() {
+ return this.getEach('firstName', 'lastName').compact().join(' ');
+ }.property('firstName', 'lastName')
+ ```
+
+ When you call `get` on a computed property, the function will be
+ called and the return value will be returned instead of the function
+ itself.
+
+ ### Unknown Properties
+
+ Likewise, if you try to call `get` on a property whose value is
+ `undefined`, the `unknownProperty()` method will be called on the object.
+ If this method returns any value other than `undefined`, it will be returned
+ instead. This allows you to implement "virtual" properties that are
+ not defined upfront.
+
+ @method get
+ @param {String} key The property to retrieve
+ @return {Object} The property value or undefined.
+ */
+ get: function(keyName) {
+ return get(this, keyName);
+ },
+
+ /**
+ To get multiple properties at once, call `getProperties`
+ with a list of strings or an array:
+
+ ```javascript
+ record.getProperties('firstName', 'lastName', 'zipCode'); // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
+ ```
+
+ is equivalent to:
+
+ ```javascript
+ record.getProperties(['firstName', 'lastName', 'zipCode']); // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
+ ```
+
+ @method getProperties
+ @param {String...|Array} list of keys to get
+ @return {Hash}
+ */
+ getProperties: function() {
+ var ret = {};
+ var propertyNames = arguments;
+ if (arguments.length === 1 && Ember.typeOf(arguments[0]) === 'array') {
+ propertyNames = arguments[0];
+ }
+ for(var i = 0; i < propertyNames.length; i++) {
+ ret[propertyNames[i]] = get(this, propertyNames[i]);
+ }
+ return ret;
+ },
+
+ /**
+ Sets the provided key or path to the value.
+
+ This method is generally very similar to calling `object[key] = value` or
+ `object.key = value`, except that it provides support for computed
+ properties, the `unknownProperty()` method and property observers.
+
+ ### Computed Properties
+
+ If you try to set a value on a key that has a computed property handler
+ defined (see the `get()` method for an example), then `set()` will call
+ that method, passing both the value and key instead of simply changing
+ the value itself. This is useful for those times when you need to
+ implement a property that is composed of one or more member
+ properties.
+
+ ### Unknown Properties
+
+ If you try to set a value on a key that is undefined in the target
+ object, then the `unknownProperty()` handler will be called instead. This
+ gives you an opportunity to implement complex "virtual" properties that
+ are not predefined on the object. If `unknownProperty()` returns
+ undefined, then `set()` will simply set the value on the object.
+
+ ### Property Observers
+
+ In addition to changing the property, `set()` will also register a property
+ change with the object. Unless you have placed this call inside of a
+ `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
+ (i.e. observer methods declared on the same object), will be called
+ immediately. Any "remote" observers (i.e. observer methods declared on
+ another object) will be placed in a queue and called at a later time in a
+ coalesced manner.
+
+ ### Chaining
+
+ In addition to property changes, `set()` returns the value of the object
+ itself so you can do chaining like this:
+
+ ```javascript
+ record.set('firstName', 'Charles').set('lastName', 'Jolley');
+ ```
+
+ @method set
+ @param {String} key The property to set
+ @param {Object} value The value to set or `null`.

+ value is set, regardless of whether it has actually changed. Your
+ observer should be prepared to handle that.
+
+ You can also pass an optional context parameter to this method. The
+ context will be passed to your observer method whenever it is triggered.
+ Note that if you add the same target/method pair on a key multiple times
+ with different context parameters, your observer will only be called once
+ with the last context you passed.
+
+ ### Observer Methods
+
+ Observer methods you pass should generally have the following signature if
+ you do not pass a `context` parameter:
+
+ ```javascript
+ fooDidChange: function(sender, key, value, rev) { };
+ ```
+
+ The sender is the object that changed. The key is the property that
+ changes. The value property is currently reserved and unused. The rev
+ is the last property revision of the object when it changed, which you can
+ use to detect if the key value has really changed or not.
+
+ If you pass a `context` parameter, the context will be passed before the
+ revision like so:
+
+ ```javascript
+ fooDidChange: function(sender, key, value, context, rev) { };
+ ```
+
+ Usually you will not need the value, context or revision parameters at
+ the end. In this case, it is common to write observer methods that take
+ only a sender and key value as parameters or, if you aren't interested in
+ any of these values, to write an observer that has no parameters at all.

+ Defines the properties that will be concatenated from the superclass
+ (instead of overridden).
+
+ By default, when you extend an Ember class a property defined in
+ the subclass overrides a property with the same name that is defined
+ in the superclass. However, there are some cases where it is preferable
+ to build up a property's value by combining the superclass' property
+ value with the subclass' value. An example of this in use within Ember
+ is the `classNames` property of `Ember.View`.
+
+ Here is some sample code showing the difference between a concatenated
+ property and a normal one:
+
+ ```javascript
+ App.BarView = Ember.View.extend({
+ someNonConcatenatedProperty: ['bar'],
+ classNames: ['bar']
+ });
+
+ App.FooBarView = App.BarView.extend({
+ someNonConcatenatedProperty: ['foo'],
+ classNames: ['foo'],
+ });
+
+ var fooBarView = App.FooBarView.create();
+ fooBarView.get('someNonConcatenatedProperty'); // ['foo']
+ fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
+ ```
+
+ This behavior extends to object creation as well. Continuing the
+ above example:
+
+ ```javascript
+ var view = App.FooBarView.create({
+ someNonConcatenatedProperty: ['baz'],
+ classNames: ['baz']
+ })
+ view.get('someNonConcatenatedProperty'); // ['baz']
+ view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+ ```
+ Adding a single property that is not an array will just add it in the array:
+
+ ```javascript
+ var view = App.FooBarView.create({
+ classNames: 'baz'
+ })
+ view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+ ```
+
+ Using the `concatenatedProperties` property, we can tell to Ember that mix
+ the content of the properties.
+
+ In `Ember.View` the `classNameBindings` and `attributeBindings` properties
+ are also concatenated, in addition to `classNames`.
+
+ This feature is available for you to use throughout the Ember object model,
+ although typical app developers are likely to use it infrequently.

+ An unordered collection of objects.
+
+ A Set works a bit like an array except that its items are not ordered. You
+ can create a set to efficiently test for membership for an object. You can
+ also iterate through a set just like an array, even accessing objects by
+ index, however there is no guarantee as to their order.
+
+ All Sets are observable via the Enumerable Observer API - which works
+ on any enumerable object including both Sets and Arrays.
+
+ ## Creating a Set
+
+ You can create a set like you would most objects using
+ `new Ember.Set()`. Most new sets you create will be empty, but you can
+ also initialize the set with some content by passing an array or other
+ enumerable of objects to the constructor.
+
+ Finally, you can pass in an existing set and the set will be copied. You
+ can also create a copy of a set by calling `Ember.Set#copy()`.
+
+ ```javascript
+ // creates a new empty set
+ var foundNames = new Ember.Set();
+
+ // creates a set with four names in it.
+ var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P
+
+ // creates a copy of the names set.
+ var namesCopy = new Ember.Set(names);
+
+ // same as above.
+ var anotherNamesCopy = names.copy();
+ ```
+
+ ## Adding/Removing Objects
+
+ You generally add or remove objects from a set using `add()` or
+ `remove()`. You can add any type of object including primitives such as
+ numbers, strings, and booleans.
+
+ Unlike arrays, objects can only exist one time in a set. If you call `add()`
+ on a set with the same object multiple times, the object will only be added
+ once. Likewise, calling `remove()` with the same object multiple times will
+ remove the object the first time and have no effect on future calls until
+ you add the object to the set again.
+
+ NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
+ so will be ignored.
+
+ In addition to add/remove you can also call `push()`/`pop()`. Push behaves
+ just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
+ object, remove it and return it. This is a good way to use a set as a job
+ queue when you don't care which order the jobs are executed in.
+
+ ## Testing for an Object
+
+ To test for an object's presence in a set you simply call
+ `Ember.Set#contains()`.
+
+ ## Observing changes
+
+ When using `Ember.Set`, you can observe the `"[]"` property to be
+ alerted whenever the content changes. You can also add an enumerable
+ observer to the set to be notified of specific objects that are added and
+ removed from the set. See `Ember.Enumerable` for more information on
+ enumerables.
+
+ This is often unhelpful. If you are filtering sets of objects, for instance,
+ it is very inefficient to re-filter all of the items each time the set
+ changes. It would be better if you could just adjust the filtered set based
+ on what was changed on the original set. The same issue applies to merging
+ sets, as well.
+
+ ## Other Methods
+
+ `Ember.Set` primary implements other mixin APIs. For a complete reference
+ on the methods you will use with `Ember.Set`, please consult these mixins.
+ The most useful ones will be `Ember.Enumerable` and
+ `Ember.MutableEnumerable` which implement most of the common iterator
+ methods you are used to on Array.
+
+ Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
+ APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
+ modified. The benefit of this is that when you call `frozenCopy()` on it,
+ Ember will avoid making copies of the set. This allows you to write
+ code that can know with certainty when the underlying set data will or
+ will not be modified.

+/**
+ `Ember.ArrayController` provides a way for you to publish a collection of
+ objects so that you can easily bind to the collection from a Handlebars
+ `#each` helper, an `Ember.CollectionView`, or other controllers.
+
+ The advantage of using an `ArrayController` is that you only have to set up
+ your view bindings once; to change what's displayed, simply swap out the
+ `content` property on the controller.
+
+ For example, imagine you wanted to display a list of items fetched via an XHR
+ request. Create an `Ember.ArrayController` and set its `content` property:
+
+ ```javascript
+ MyApp.listController = Ember.ArrayController.create();
+
+ $.get('people.json', function(data) {
+ MyApp.listController.set('content', data);
+ });
+ ```
+
+ Then, create a view that binds to your new controller:
+
+ ```handlebars
+ {{#each MyApp.listController}}
+ {{firstName}} {{lastName}}
+ {{/each}}
+ ```
+
+ Although you are binding to the controller, the behavior of this controller
+ is to pass through any methods or properties to the underlying array. This
+ capability comes from `Ember.ArrayProxy`, which this class inherits from.
+
+ Sometimes you want to display computed properties within the body of an
+ `#each` helper that depend on the underlying items in `content`, but are not
+ present on those items. To do this, set `itemController` to the name of a
+ controller (probably an `ObjectController`) that will wrap each individual item.
+
+ For example:
+
+ ```handlebars
+ {{#each post in controller}}
+ <li>{{title}} ({{titleLength}} characters)</li>
+ {{/each}}
+ ```
+
+ ```javascript
+ App.PostsController = Ember.ArrayController.extend({
+ itemController: 'post'
+ });
+
+ App.PostController = Ember.ObjectController.extend({
+ // the `title` property will be proxied to the underlying post.
+
+ titleLength: function() {
+ return this.get('title').length;
+ }.property('title')
+ });
+ ```
+
+ In some cases it is helpful to return a different `itemController` depending
+ on the particular item. Subclasses can do this by overriding
+ `lookupItemController`.
+
+ For example:
+
+ ```javascript
+ App.MyArrayController = Ember.ArrayController.extend({
+ lookupItemController: function( object ) {
+ if (object.get('isSpecial')) {
+ return "special"; // use App.SpecialController
+ } else {
+ return "regular"; // use App.RegularController
+ }
+ }
+ });
+ ```

+/**
+ `Ember.View` is the class in Ember responsible for encapsulating templates of
+ HTML content, combining templates with data to render as sections of a page's
+ DOM, and registering and responding to user-initiated events.
+
+ ## HTML Tag
+
+ The default HTML tag name used for a view's DOM representation is `div`. This
+ can be customized by setting the `tagName` property. The following view
+class:
+
+ ```javascript
+ ParagraphView = Ember.View.extend({
+ tagName: 'em'
+ });
+ ```
+
+ Would result in instances with the following HTML:
+
+ ```html
+ <em id="ember1" class="ember-view"></em>
+ ```
+
+ ## HTML `class` Attribute
+
+ The HTML `class` attribute of a view's tag can be set by providing a
+ `classNames` property that is set to an array of strings:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNames: ['my-class', 'my-other-class']
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view my-class my-other-class"></div>
+ ```
+
+ `class` attribute values can also be set by providing a `classNameBindings`
+ property set to an array of properties names for the view. The return value
+ of these properties will be added as part of the value for the view's `class`
+ attribute. These properties can be computed properties:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['propertyA', 'propertyB'],
+ propertyA: 'from-a',
+ propertyB: function(){
+ if(someLogic){ return 'from-b'; }
+ }.property()
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view from-a from-b"></div>
+ ```
+
+ If the value of a class name binding returns a boolean the property name
+ itself will be used as the class name if the property is true. The class name
+ will not be added if the value is `false` or `undefined`.
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['hovered'],
+ hovered: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view hovered"></div>
+ ```
+
+ When using boolean class name bindings you can supply a string value other
+ than the property name for use as the `class` HTML attribute by appending the
+ preferred value after a ":" character when defining the binding:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['awesome:so-very-cool'],
+ awesome: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view so-very-cool"></div>
+ ```
+
+ Boolean value class name bindings whose property names are in a
+ camelCase-style format will be converted to a dasherized format:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['isUrgent'],
+ isUrgent: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view is-urgent"></div>
+ ```
+
+ Class name bindings can also refer to object values that are found by
+ traversing a path relative to the view itself:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['messages.empty']
+ messages: Ember.Object.create({
+ empty: true
+ })
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view empty"></div>
+ ```
+
+ If you want to add a class name for a property which evaluates to true and
+ and a different class name if it evaluates to false, you can pass a binding
+ like this:
+
+ ```javascript
+ // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
+ Ember.View.create({
+ classNameBindings: ['isEnabled:enabled:disabled']
+ isEnabled: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view enabled"></div>
+ ```
+
+ When isEnabled is `false`, the resulting HTML reprensentation looks like
+ this:
+
+ ```html
+ <div id="ember1" class="ember-view disabled"></div>
+ ```
+
+ This syntax offers the convenience to add a class if a property is `false`:
+
+ ```javascript
+ // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
+ Ember.View.create({
+ classNameBindings: ['isEnabled::disabled']
+ isEnabled: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view"></div>
+ ```
+
+ When the `isEnabled` property on the view is set to `false`, it will result
+ in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view disabled"></div>
+ ```
+
+ Updates to the the value of a class name binding will result in automatic
+ update of the HTML `class` attribute in the view's rendered HTML
+ representation. If the value becomes `false` or `undefined` the class name
+ will be removed.
+
+ Both `classNames` and `classNameBindings` are concatenated properties. See
+ `Ember.Object` documentation for more information about concatenated
+ properties.
+
+ ## HTML Attributes
+
+ The HTML attribute section of a view's tag can be set by providing an
+ `attributeBindings` property set to an array of property names on the view.
+ The return value of these properties will be used as the value of the view's
+ HTML associated attribute:
+
+ ```javascript
+ AnchorView = Ember.View.extend({
+ tagName: 'a',
+ attributeBindings: ['href'],
+ href: 'http://google.com'
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <a id="ember1" class="ember-view" href="http://google.com"></a>
+ ```
+
+ If the return value of an `attributeBindings` monitored property is a boolean
+ the property will follow HTML's pattern of repeating the attribute's name as
+ its value:
+
+ ```javascript
+ MyTextInput = Ember.View.extend({
+ tagName: 'input',
+ attributeBindings: ['disabled'],
+ disabled: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <input id="ember1" class="ember-view" disabled="disabled" />
+ ```
+
+ `attributeBindings` can refer to computed properties:
+
+ ```javascript
+ MyTextInput = Ember.View.extend({
+ tagName: 'input',
+ attributeBindings: ['disabled'],
+ disabled: function(){
+ if (someLogic) {
+ return true;
+ } else {
+ return false;
+ }
+ }.property()
+ });
+ ```
+
+ Updates to the the property of an attribute binding will result in automatic
+ update of the HTML attribute in the view's rendered HTML representation.
+
+ `attributeBindings` is a concatenated property. See `Ember.Object`
+ documentation for more information about concatenated properties.
+
+ ## Templates
+
+ The HTML contents of a view's rendered representation are determined by its
+ template. Templates can be any function that accepts an optional context
+ parameter and returns a string of HTML that will be inserted within the
+ view's tag. Most typically in Ember this function will be a compiled
+ `Ember.Handlebars` template.
+
+ ```javascript
+ AView = Ember.View.extend({
+ template: Ember.Handlebars.compile('I am the template')
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view">I am the template</div>
+ ```
+
+ Within an Ember application is more common to define a Handlebars templates as
+ part of a page:
+
+ ```html
+ <script type='text/x-handlebars' data-template-name='some-template'>
+ Hello
+ </script>
+ ```
+
+ And associate it by name using a view's `templateName` property:
+
+ ```javascript
+ AView = Ember.View.extend({
+ templateName: 'some-template'
+ });
+ ```
+
+ Using a value for `templateName` that does not have a Handlebars template
+ with a matching `data-template-name` attribute will throw an error.
+
+ Assigning a value to both `template` and `templateName` properties will throw
+ an error.
+
+ For views classes that may have a template later defined (e.g. as the block
+ portion of a `{{view}}` Handlebars helper call in another template or in
+ a subclass), you can provide a `defaultTemplate` property set to compiled
+ template function. If a template is not later provided for the view instance
+ the `defaultTemplate` value will be used:
+
+ ```javascript
+ AView = Ember.View.extend({
+ defaultTemplate: Ember.Handlebars.compile('I was the default'),
+ template: null,
+ templateName: null
+ });
+ ```
+
+ Will result in instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view">I was the default</div>
+ ```
+
+ If a `template` or `templateName` is provided it will take precedence over
+ `defaultTemplate`:
+
+ ```javascript
+ AView = Ember.View.extend({
+ defaultTemplate: Ember.Handlebars.compile('I was the default')
+ });
+
+ aView = AView.create({
+ template: Ember.Handlebars.compile('I was the template, not default')
+ });
+ ```
+
+ Will result in the following HTML representation when rendered:
+
+ ```html
+ <div id="ember1" class="ember-view">I was the template, not default</div>
+ ```
+
+ ## View Context
+
+ The default context of the compiled template is the view's controller:
+
+ ```javascript
+ AView = Ember.View.extend({
+ template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
+ });
+
+ aController = Ember.Object.create({
+ firstName: 'Barry',
+ excitedGreeting: function(){
+ return this.get("content.firstName") + "!!!"
+ }.property()
+ });
+
+ aView = AView.create({
+ controller: aController,
+ });
+ ```
+
+ Will result in an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view">Hello Barry!!!</div>
+ ```
+
+ A context can also be explicitly supplied through the view's `context`
+ property. If the view has neither `context` nor `controller` properties, the
+ `parentView`'s context will be used.
+
+ ## Layouts
+
+ Views can have a secondary template that wraps their main template. Like
+ primary templates, layouts can be any function that accepts an optional
+ context parameter and returns a string of HTML that will be inserted inside
+ view's tag. Views whose HTML element is self closing (e.g. `<input />`)
+ cannot have a layout and this property will be ignored.
+
+ Most typically in Ember a layout will be a compiled `Ember.Handlebars`
+ template.
+
+ A view's layout can be set directly with the `layout` property or reference
+ an existing Handlebars template by name with the `layoutName` property.
+
+ A template used as a layout must contain a single use of the Handlebars
+ `{{yield}}` helper. The HTML contents of a view's rendered `template` will be
+ inserted at this location:
+
+ ```javascript
+ AViewWithLayout = Ember.View.extend({
+ layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>")
+ template: Ember.Handlebars.compile("I got wrapped"),
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view">
+ <div class="my-decorative-class">
+ I got wrapped
+ </div>
+ </div>
+ ```
+
+ See `Handlebars.helpers.yield` for more information.
+
+ ## Responding to Browser Events
+
+ Views can respond to user-initiated events in one of three ways: method
+ implementation, through an event manager, and through `{{action}}` helper use
+ in their template or layout.
+
+ ### Method Implementation
+
+ Views can respond to user-initiated events by implementing a method that
+ matches the event name. A `jQuery.Event` object will be passed as the
+ argument to this method.
+
+ ```javascript
+ AView = Ember.View.extend({
+ click: function(event){
+ // will be called when when an instance's
+ // rendered element is clicked
+ }
+ });
+ ```
+
+ ### Event Managers
+
+ Views can define an object as their `eventManager` property. This object can
+ then implement methods that match the desired event names. Matching events
+ that occur on the view's rendered HTML or the rendered HTML of any of its DOM
+ descendants will trigger this method. A `jQuery.Event` object will be passed
+ as the first argument to the method and an `Ember.View` object as the
+ second. The `Ember.View` will be the view whose rendered HTML was interacted
+ with. This may be the view with the `eventManager` property or one of its
+ descendent views.
+
+ ```javascript
+ AView = Ember.View.extend({
+ eventManager: Ember.Object.create({
+ doubleClick: function(event, view){
+ // will be called when when an instance's
+ // rendered element or any rendering
+ // of this views's descendent
+ // elements is clicked
+ }
+ })
+ });
+ ```
+
+ An event defined for an event manager takes precedence over events of the
+ same name handled through methods on the view.
+
+ ```javascript
+ AView = Ember.View.extend({
+ mouseEnter: function(event){
+ // will never trigger.
+ },
+ eventManager: Ember.Object.create({
+ mouseEnter: function(event, view){
+ // takes presedence over AView#mouseEnter
+ }
+ })
+ });
+ ```
+
+ Similarly a view's event manager will take precedence for events of any views
+ rendered as a descendent. A method name that matches an event name will not
+ be called if the view instance was rendered inside the HTML representation of
+ a view that has an `eventManager` property defined that handles events of the
+ name. Events not handled by the event manager will still trigger method calls
+ on the descendent.
+
+ ```javascript
+ OuterView = Ember.View.extend({
+ template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"),
+ eventManager: Ember.Object.create({
+ mouseEnter: function(event, view){
+ // view might be instance of either
+ // OutsideView or InnerView depending on
+ // where on the page the user interaction occured
+ }
+ })
+ });
+
+ InnerView = Ember.View.extend({
+ click: function(event){
+ // will be called if rendered inside
+ // an OuterView because OuterView's
+ // eventManager doesn't handle click events
+ },
+ mouseEnter: function(event){
+ // will never be called if rendered inside
+ // an OuterView.
+ }
+ });
+ ```
+
+ ### Handlebars `{{action}}` Helper
+
+ See `Handlebars.helpers.action`.
+
+ ### Event Names
+
+ Possible events names for any of the responding approaches described above
+ are:
+
+ Touch events:
+
+ * `touchStart`
+ * `touchMove`
+ * `touchEnd`
+ * `touchCancel`
+
+ Keyboard events
+
+ * `keyDown`
+ * `keyUp`
+ * `keyPress`
+
+ Mouse events
+
+ * `mouseDown`
+ * `mouseUp`
+ * `contextMenu`
+ * `click`
+ * `doubleClick`
+ * `mouseMove`
+ * `focusIn`
+ * `focusOut`
+ * `mouseEnter`
+ * `mouseLeave`
+
+ Form events:
+
+ * `submit`
+ * `change`
+ * `focusIn`
+ * `focusOut`
+ * `input`
+
+ HTML5 drag and drop events:
+
+ * `dragStart`
+ * `drag`
+ * `dragEnter`
+ * `dragLeave`
+ * `drop`
+ * `dragEnd`
+
+ ## Handlebars `{{view}}` Helper
+
+ Other `Ember.View` instances can be included as part of a view's template by
+ using the `{{view}}` Handlebars helper. See `Handlebars.helpers.view` for
+ additional information.

+ A `ContainerView` is an `Ember.View` subclass that implements `Ember.MutableArray`
+ allowing programatic management of its child views.
+
+ ## Setting Initial Child Views
+
+ The initial array of child views can be set in one of two ways. You can
+ provide a `childViews` property at creation time that contains instance of
+ `Ember.View`:
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ childViews: [Ember.View.create(), Ember.View.create()]
+ });
+ ```
+
+ You can also provide a list of property names whose values are instances of
+ `Ember.View`:
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ childViews: ['aView', 'bView', 'cView'],
+ aView: Ember.View.create(),
+ bView: Ember.View.create(),
+ cView: Ember.View.create()
+ });
+ ```
+
+ The two strategies can be combined:
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ childViews: ['aView', Ember.View.create()],
+ aView: Ember.View.create()
+ });
+ ```
+
+ Each child view's rendering will be inserted into the container's rendered
+ HTML in the same order as its position in the `childViews` property.
+
+ ## Adding and Removing Child Views
+
+ The container view implements `Ember.MutableArray` allowing programatic management of its child views.
+
+ To remove a view, pass that view into a `removeObject` call on the container view.
+
+ Given an empty `<body>` the following code
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ classNames: ['the-container'],
+ childViews: ['aView', 'bView'],
+ aView: Ember.View.create({
+ template: Ember.Handlebars.compile("A")
+ }),
+ bView: Ember.View.create({
+ template: Ember.Handlebars.compile("B")
+ })
+ });
+
+ aContainer.appendTo('body');
+ ```
+
+ Results in the HTML
+
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ <div class="ember-view">B</div>
+ </div>
+ ```
+
+ Removing a view
+
+ ```javascript
+ aContainer.toArray(); // [aContainer.aView, aContainer.bView]
+ aContainer.removeObject(aContainer.get('bView'));
+ aContainer.toArray(); // [aContainer.aView]
+ ```
+
+ Will result in the following HTML
+
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ </div>
+ ```
+
+ Similarly, adding a child view is accomplished by adding `Ember.View` instances to the
+ container view.
+
+ Given an empty `<body>` the following code
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ classNames: ['the-container'],
+ childViews: ['aView', 'bView'],
+ aView: Ember.View.create({
+ template: Ember.Handlebars.compile("A")
+ }),
+ bView: Ember.View.create({
+ template: Ember.Handlebars.compile("B")
+ })
+ });
+
+ aContainer.appendTo('body');
+ ```
+
+ Results in the HTML
+
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ <div class="ember-view">B</div>
+ </div>
+ ```
+
+ Adding a view
+
+ ```javascript
+ AnotherViewClass = Ember.View.extend({
+ template: Ember.Handlebars.compile("Another view")
+ });
+
+ aContainer.toArray(); // [aContainer.aView, aContainer.bView]
+ aContainer.pushObject(AnotherViewClass.create());
+ aContainer.toArray(); // [aContainer.aView, aContainer.bView, <AnotherViewClass instance>]
+ ```
+
+ Will result in the following HTML
+
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ <div class="ember-view">B</div>
+ <div class="ember-view">Another view</div>
+ </div>
+ ```
+
+ ## Templates and Layout
+
+ A `template`, `templateName`, `defaultTemplate`, `layout`, `layoutName` or
+ `defaultLayout` property on a container view will not result in the template
+ or layout being rendered. The HTML contents of a `Ember.ContainerView`'s DOM
+ representation will only be the rendered HTML of its child views.
+
+ ## Binding a View to Display
+
+ If you would like to display a single view in your ContainerView, you can set
+ its `currentView` property. When the `currentView` property is set to a view
+ instance, it will be added to the ContainerView. If the `currentView` property
+ is later changed to a different view, the new view will replace the old view.
+ If `currentView` is set to `null`, the last `currentView` will be removed.
+
+ This functionality is useful for cases where you want to bind the display of
+ a ContainerView to a controller or state manager. For example, you can bind
+ the `currentView` of a container to a controller like this:
+
+ ```javascript
+ App.appController = Ember.Object.create({
+ view: Ember.View.create({
+ templateName: 'person_template'
+ })
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.ContainerView currentViewBinding="App.appController.view"}}
+ ```

+ `Ember.CollectionView` is an `Ember.View` descendent responsible for managing
+ a collection (an array or array-like object) by maintaing a child view object
+ and associated DOM representation for each item in the array and ensuring
+ that child views and their associated rendered HTML are updated when items in
+ the array are added, removed, or replaced.
+
+ ## Setting content
+
+ The managed collection of objects is referenced as the `Ember.CollectionView`
+ instance's `content` property.
+
+ ```javascript
+ someItemsView = Ember.CollectionView.create({
+ content: ['A', 'B','C']
+ })
+ ```
+
+ The view for each item in the collection will have its `content` property set
+ to the item.
+
+ ## Specifying itemViewClass
+
+ By default the view class for each item in the managed collection will be an
+ instance of `Ember.View`. You can supply a different class by setting the
+ `CollectionView`'s `itemViewClass` property.
+
+ Given an empty `<body>` and the following code:
+
+ ```javascript
+ someItemsView = Ember.CollectionView.create({
+ classNames: ['a-collection'],
+ content: ['A','B','C'],
+ itemViewClass: Ember.View.extend({
+ template: Ember.Handlebars.compile("the letter: {{view.content}}")
+ })
+ });
+
+ someItemsView.appendTo('body');
+ ```
+
+ Will result in the following HTML structure
+
+ ```html
+ <div class="ember-view a-collection">
+ <div class="ember-view">the letter: A</div>
+ <div class="ember-view">the letter: B</div>
+ <div class="ember-view">the letter: C</div>
+ </div>
+ ```
+
+ ## Automatic matching of parent/child tagNames
+
+ Setting the `tagName` property of a `CollectionView` to any of
+ "ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
+ in the item views receiving an appropriately matched `tagName` property.
+
+ Given an empty `<body>` and the following code:
+
+ ```javascript
+ anUndorderedListView = Ember.CollectionView.create({
+ tagName: 'ul',
+ content: ['A','B','C'],
+ itemViewClass: Ember.View.extend({
+ template: Ember.Handlebars.compile("the letter: {{view.content}}")
+ })
+ });
+
+ anUndorderedListView.appendTo('body');
+ ```
+
+ Will result in the following HTML structure
+
+ ```html
+ <ul class="ember-view a-collection">
+ <li class="ember-view">the letter: A</li>
+ <li class="ember-view">the letter: B</li>
+ <li class="ember-view">the letter: C</li>
+ </ul>
+ ```
+
+ Additional `tagName` pairs can be provided by adding to
+ `Ember.CollectionView.CONTAINER_MAP `
+
+ ```javascript
+ Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
+ ```
+
+ ## Programatic creation of child views
+
+ For cases where additional customization beyond the use of a single
+ `itemViewClass` or `tagName` matching is required CollectionView's
+ `createChildView` method can be overidden:
+
+ ```javascript
+ CustomCollectionView = Ember.CollectionView.extend({
+ createChildView: function(viewClass, attrs) {
+ if (attrs.content.kind == 'album') {
+ viewClass = App.AlbumView;
+ } else {
+ viewClass = App.SongView;
+ }
+ this._super(viewClass, attrs);
+ }
+ });
+ ```
+
+ ## Empty View
+
+ You can provide an `Ember.View` subclass to the `Ember.CollectionView`
+ instance as its `emptyView` property. If the `content` property of a
+ `CollectionView` is set to `null` or an empty array, an instance of this view
+ will be the `CollectionView`s only child.
+
+ ```javascript
+ aListWithNothing = Ember.CollectionView.create({
+ classNames: ['nothing']
+ content: null,
+ emptyView: Ember.View.extend({
+ template: Ember.Handlebars.compile("The collection is empty")
+ })
+ });
+
+ aListWithNothing.appendTo('body');
+ ```
+
+ Will result in the following HTML structure
+
+ ```html
+ <div class="ember-view nothing">
+ <div class="ember-view">
+ The collection is empty
+ </div>
+ </div>
+ ```
+
+ ## Adding and Removing items
+
+ The `childViews` property of a `CollectionView` should not be directly
+ manipulated. Instead, add, remove, replace items from its `content` property.
+ This will trigger appropriate changes to its rendered HTML.
+
+ ## Use in templates via the `{{collection}}` `Ember.Handlebars` helper
+
+ `Ember.Handlebars` provides a helper specifically for adding
+ `CollectionView`s to templates. See `Ember.Handlebars.collection` for more
+ details

+/**
+ Register a bound handlebars helper. Bound helpers behave similarly to regular
+ handlebars helpers, with the added ability to re-render when the underlying data
+ changes.
+
+ ## Simple example
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('capitalize', function(value) {
+ return value.toUpperCase();
+ });
+ ```
+
+ The above bound helper can be used inside of templates as follows:
+
+ ```handlebars
+ {{capitalize name}}
+ ```
+
+ In this case, when the `name` property of the template's context changes,
+ the rendered value of the helper will update to reflect this change.
+
+ ## Example with options
+
+ Like normal handlebars helpers, bound helpers have access to the options
+ passed into the helper call.
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('repeat', function(value, options) {
+ var count = options.hash.count;
+ var a = [];
+ while(a.length < count){
+ a.push(value);
+ }
+ return a.join('');
+ });
+ ```
+
+ This helper could be used in a template as follows:
+
+ ```handlebars
+ {{repeat text count=3}}
+ ```
+
+ ## Example with bound options
+
+ Bound hash options are also supported. Example:
+
+ ```handlebars
+ {{repeat text countBinding="numRepeats"}}
+ ```
+
+ In this example, count will be bound to the value of
+ the `numRepeats` property on the context. If that property
+ changes, the helper will be re-rendered.
+
+ ## Example with extra dependencies
+
+ The `Ember.Handlebars.registerBoundHelper` method takes a variable length
+ third parameter which indicates extra dependencies on the passed in value.
+ This allows the handlebars helper to update when these dependencies change.
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
+ return value.get('name').toUpperCase();
+ }, 'name');
+ ```
+
+ ## Example with multiple bound properties
+
+ `Ember.Handlebars.registerBoundHelper` supports binding to
+ multiple properties, e.g.:
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('concatenate', function() {
+ var values = arguments[arguments.length - 1];
+ return values.join('||');
+ });
+ ```
+
+ Which allows for template syntax such as {{concatenate prop1 prop2}} or
+ {{concatenate prop1 prop2 prop3}}. If any of the properties change,
+ the helpr will re-render. Note that dependency keys cannot be
+ using in conjunction with multi-property helpers, since it is ambiguous
+ which property the dependent keys would belong to.
+
+ ## Use with unbound helper
+
+ The {{unbound}} helper can be used with bound helper invocations
+ to render them in their unbound form, e.g.
+
+ ```handlebars
+ {{unbound capitalize name}}
+ ```
+
+ In this example, if the name property changes, the helper
+ will not re-render.

+/**
+ `bindAttr` allows you to create a binding between DOM element attributes and
+ Ember objects. For example:
+
+ ```handlebars
+ <img {{bindAttr src="imageUrl" alt="imageTitle"}}>
+ ```
+
+ The above handlebars template will fill the `<img>`'s `src` attribute will
+ the value of the property referenced with `"imageUrl"` and its `alt`
+ attribute with the value of the property referenced with `"imageTitle"`.
+
+ If the rendering context of this template is the following object:
+
+ ```javascript
+ {
+ imageUrl: 'http://lolcats.info/haz-a-funny',
+ imageTitle: 'A humorous image of a cat'
+ }
+ ```
+
+ The resulting HTML output will be:
+
+ ```html
+ <img src="http://lolcats.info/haz-a-funny" alt="A humorous image of a cat">
+ ```
+
+ `bindAttr` cannot redeclare existing DOM element attributes. The use of `src`
+ in the following `bindAttr` example will be ignored and the hard coded value
+ of `src="/failwhale.gif"` will take precedence:
+
+ ```handlebars
+ <img src="/failwhale.gif" {{bindAttr src="imageUrl" alt="imageTitle"}}>
+ ```
+
+ ### `bindAttr` and the `class` attribute
+
+ `bindAttr` supports a special syntax for handling a number of cases unique
+ to the `class` DOM element attribute. The `class` attribute combines
+ multiple discreet values into a single attribute as a space-delimited
+ list of strings. Each string can be:
+
+ * a string return value of an object's property.
+ * a boolean return value of an object's property
+ * a hard-coded value
+
+ A string return value works identically to other uses of `bindAttr`. The
+ return value of the property will become the value of the attribute. For
+ example, the following view and template:
+
+ ```javascript
+ AView = Ember.View.extend({
+ someProperty: function(){
+ return "aValue";
+ }.property()
+ })
+ ```
+
+ ```handlebars
+ <img {{bindAttr class="view.someProperty}}>
+ ```
+
+ Result in the following rendered output:
+
+ ```html
+ <img class="aValue">
+ ```
+
+ A boolean return value will insert a specified class name if the property
+ returns `true` and remove the class name if the property returns `false`.
+
+ A class name is provided via the syntax
+ `somePropertyName:class-name-if-true`.
+
+ ```javascript
+ AView = Ember.View.extend({
+ someBool: true
+ })
+ ```
+
+ ```handlebars
+ <img {{bindAttr class="view.someBool:class-name-if-true"}}>
+ ```
+
+ Result in the following rendered output:
+
+ ```html
+ <img class="class-name-if-true">
+ ```
+
+ An additional section of the binding can be provided if you want to
+ replace the existing class instead of removing it when the boolean
+ value changes:
+
+ ```handlebars
+ <img {{bindAttr class="view.someBool:class-name-if-true:class-name-if-false"}}>
+ ```
+
+ A hard-coded value can be used by prepending `:` to the desired
+ class name: `:class-name-to-always-apply`.
+
+ ```handlebars
+ <img {{bindAttr class=":class-name-to-always-apply"}}>
+ ```
+
+ Results in the following rendered output:
+
+ ```html
+ <img class=":class-name-to-always-apply">
+ ```
+
+ All three strategies - string return value, boolean return value, and
+ hard-coded value – can be combined in a single declaration:
+
+ ```handlebars
+ <img {{bindAttr class=":class-name-to-always-apply view.someBool:class-name-if-true view.someProperty"}}>
+ ```

+ aView.appendTo('body');
+ ```
+
+ Will result in HTML structure:
+
+ ```html
+ <div id="ember1" class="ember-view">
+ <div id="ember2" class="ember-view">
+ my parent: ember1
+ </div>
+ </div>
+ ```
+
+ ### Setting CSS id and class attributes
+
+ The HTML `id` attribute can be set on the `{{view}}`'s resulting element with
+ the `id` option. This option will _not_ be passed to `Ember.View.create`.
+
+ ```handlebars
+ {{#view tagName="span" id="a-custom-id"}}
+ hello.
+ {{/view}}
+ ```
+
+ Results in the following HTML structure:
+
+ ```html
+ <div class="ember-view">
+ <span id="a-custom-id" class="ember-view">
+ hello.
+ </span>
+ </div>
+ ```
+
+ The HTML `class` attribute can be set on the `{{view}}`'s resulting element
+ with the `class` or `classNameBindings` options. The `class` option will
+ directly set the CSS `class` attribute and will not be passed to
+ `Ember.View.create`. `classNameBindings` will be passed to `create` and use
+ `Ember.View`'s class name binding functionality:
+
+ ```handlebars
+ {{#view tagName="span" class="a-custom-class"}}
+ hello.
+ {{/view}}
+ ```
+
+ Results in the following HTML structure:
+
+ ```html
+ <div class="ember-view">
+ <span id="ember2" class="ember-view a-custom-class">
+ hello.
+ </span>
+ </div>
+ ```
+
+ ### Supplying a different view class
+
+ `{{view}}` can take an optional first argument before its supplied options to
+ specify a path to a custom view class.
+
+ ```handlebars
+ {{#view "MyApp.CustomView"}}
+ hello.
+ {{/view}}
+ ```
+
+ The first argument can also be a relative path. Ember will search for the
+ view class starting at the `Ember.View` of the template where `{{view}}` was
+ used as the root object:
+
+ ```javascript
+ MyApp = Ember.Application.create({});
+ MyApp.OuterView = Ember.View.extend({
+ innerViewClass: Ember.View.extend({
+ classNames: ['a-custom-view-class-as-property']
+ }),
+ template: Ember.Handlebars.compile('{{#view "innerViewClass"}} hi {{/view}}')
+ });
+
+ MyApp.OuterView.create().appendTo('body');
+ ```
+
+ Will result in the following HTML:
+
+ ```html
+ <div id="ember1" class="ember-view">
+ <div id="ember2" class="ember-view a-custom-view-class-as-property">
+ hi
+ </div>
+ </div>
+ ```
+
+ ### Blockless use
+
+ If you supply a custom `Ember.View` subclass that specifies its own template
+ or provide a `templateName` option to `{{view}}` it can be used without
+ supplying a block. Attempts to use both a `templateName` option and supply a
+ block will throw an error.
+
+ ```handlebars
+ {{view "MyApp.ViewWithATemplateDefined"}}
+ ```
+
+ ### `viewName` property
+
+ You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance
+ will be referenced as a property of its parent view by this name.
+
+ ```javascript
+ aView = Ember.View.create({
+ template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}')
+ });
+
+ aView.appendTo('body');
+ aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper
+ ```
+
+ @method view
+ @for Ember.Handlebars.helpers
+ @param {String} path
+ @param {Hash} options
+ @return {String} HTML string

+EmberHandlebars.registerHelper('view', function(path, options) {
+ Ember.assert("The view helper only takes a single argument", arguments.length <= 2);
+
+ // If no path is provided, treat path param as options.
+ if (path && path.data && path.data.isRenderData) {
+ options = path;
+ path = "Ember.View";
+ }
+

+/**
+ `{{collection}}` is a `Ember.Handlebars` helper for adding instances of
+ `Ember.CollectionView` to a template. See `Ember.CollectionView` for
+ additional information on how a `CollectionView` functions.
+
+ `{{collection}}`'s primary use is as a block helper with a `contentBinding`
+ option pointing towards an `Ember.Array`-compatible object. An `Ember.View`
+ instance will be created for each item in its `content` property. Each view
+ will have its own `content` property set to the appropriate item in the
+ collection.
+
+ The provided block will be applied as the template for each item's view.
+
+ Given an empty `<body>` the following template:
+
+ ```handlebars
+ {{#collection contentBinding="App.items"}}
+ Hi {{view.content.name}}
+ {{/collection}}
+ ```
+
+ And the following application code
+
+ ```javascript
+ App = Ember.Application.create()
+ App.items = [
+ Ember.Object.create({name: 'Dave'}),
+ Ember.Object.create({name: 'Mary'}),
+ Ember.Object.create({name: 'Sara'})
+ ]

+ <div class="ember-view">Hi Dave</div>
+ <div class="ember-view">Hi Mary</div>
+ <div class="ember-view">Hi Sara</div>
+ </div>
+ ```
+
+ ### Blockless Use
+
+ If you provide an `itemViewClass` option that has its own `template` you can
+ omit the block.
+
+ The following template:
+
+ ```handlebars
+ {{collection contentBinding="App.items" itemViewClass="App.AnItemView"}}
+ ```
+
+ And application code
+
+ ```javascript
+ App = Ember.Application.create();
+ App.items = [
+ Ember.Object.create({name: 'Dave'}),
+ Ember.Object.create({name: 'Mary'}),
+ Ember.Object.create({name: 'Sara'})
+ ];
+
+ App.AnItemView = Ember.View.extend({
+ template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
+ });
+ ```
+
+ Will result in the HTML structure below
+
+ ```html
+ <div class="ember-view">
+ <div class="ember-view">Greetings Dave</div>
+ <div class="ember-view">Greetings Mary</div>
+ <div class="ember-view">Greetings Sara</div>
+ </div>
+ ```
+
+ ### Specifying a CollectionView subclass
+
+ By default the `{{collection}}` helper will create an instance of
+ `Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to
+ the helper by passing it as the first argument:
+
+ ```handlebars
+ {{#collection App.MyCustomCollectionClass contentBinding="App.items"}}
+ Hi {{view.content.name}}
+ {{/collection}}
+ ```
+
+ ### Forwarded `item.*`-named Options
+
+ As with the `{{view}}`, helper options passed to the `{{collection}}` will be
+ set on the resulting `Ember.CollectionView` as properties. Additionally,
+ options prefixed with `item` will be applied to the views rendered for each
+ item (note the camelcasing):
+
+ ```handlebars
+ {{#collection contentBinding="App.items"
+ itemTagName="p"
+ itemClassNames="greeting"}}
+ Howdy {{view.content.name}}
+ {{/collection}}
+ ```
+
+ Will result in the following HTML structure:
+
+ ```html
+ <div class="ember-view">
+ <p class="ember-view greeting">Howdy Dave</p>
+ <p class="ember-view greeting">Howdy Mary</p>
+ <p class="ember-view greeting">Howdy Sara</p>

+/**
+ The `{{#each}}` helper loops over elements in a collection, rendering its
+ block once for each item. It is an extension of the base Handlebars `{{#each}}`
+ helper:
+
+ ```javascript
+ Developers = [{name: 'Yehuda'},{name: 'Tom'}, {name: 'Paul'}];
+ ```
+
+ ```handlebars
+ {{#each Developers}}
+ {{name}}
+ {{/each}}
+ ```
+
+ `{{each}}` supports an alternative syntax with element naming:
+
+ ```handlebars
+ {{#each person in Developers}}
+ {{person.name}}
+ {{/each}}
+ ```
+
+ When looping over objects that do not have properties, `{{this}}` can be used
+ to render the object:
+
+ ```javascript
+ DeveloperNames = ['Yehuda', 'Tom', 'Paul']
+ ```
+
+ ```handlebars
+ {{#each DeveloperNames}}
+ {{this}}
+ {{/each}}
+ ```
+ ### {{else}} condition
+ `{{#each}}` can have a matching `{{else}}`. The contents of this block will render
+ if the collection is empty.
+
+ ```
+ {{#each person in Developers}}
+ {{person.name}}
+ {{else}}
+ <p>Sorry, nobody is available for this task.</p>
+ {{/each}}
+ ```
+ ### Specifying a View class for items
+ If you provide an `itemViewClass` option that references a view class
+ with its own `template` you can omit the block.
+
+ The following template:
+
+ ```handlebars
+ {{#view App.MyView }}
+ {{each view.items itemViewClass="App.AnItemView"}}
+ {{/view}}
+ ```
+
+ And application code
+
+ ```javascript
+ App = Ember.Application.create({
+ MyView: Ember.View.extend({
+ items: [
+ Ember.Object.create({name: 'Dave'}),
+ Ember.Object.create({name: 'Mary'}),
+ Ember.Object.create({name: 'Sara'})
+ ]
+ })
+ });
+
+ App.AnItemView = Ember.View.extend({
+ template: Ember.Handlebars.compile("Greetings {{name}}")
+ });
+ ```
+
+ Will result in the HTML structure below
+
+ ```html
+ <div class="ember-view">
+ <div class="ember-view">Greetings Dave</div>
+ <div class="ember-view">Greetings Mary</div>
+ <div class="ember-view">Greetings Sara</div>
+ </div>
+ ```
+
+ ### Representing each item with a Controller.
+ By default the controller lookup within an `{{#each}}` block will be
+ the controller of the template where the `{{#each}}` was used. If each
+ item needs to be presented by a custom controller you can provide a
+ `itemController` option which references a controller by lookup name.
+ Each item in the loop will be wrapped in an instance of this controller
+ and the item itself will be set to the `content` property of that controller.
+
+ This is useful in cases where properties of model objects need transformation
+ or synthesis for display:
+
+ ```javascript
+ App.DeveloperController = Ember.ObjectController.extend({
+ isAvailableForHire: function(){
+ return !this.get('content.isEmployed') && this.get('content.isSeekingWork');
+ }.property('isEmployed', 'isSeekingWork')
+ })
+ ```
+

+ {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}}
+ {{/each}}
+ ```

+/**
+ The `Ember.Select` view class renders a
+ [select](https://developer.mozilla.org/en/HTML/Element/select) HTML element,
+ allowing the user to choose from a list of options.
+
+ The text and `value` property of each `<option>` element within the
+ `<select>` element are populated from the objects in the `Element.Select`'s
+ `content` property. The underlying data object of the selected `<option>` is
+ stored in the `Element.Select`'s `value` property.
+
+ ### `content` as an array of Strings
+
+ The simplest version of an `Ember.Select` takes an array of strings as its
+ `content` property. The string will be used as both the `value` property and
+ the inner text of each `<option>` element inside the rendered `<select>`.
+
+ Example:
+
+ ```javascript
+ App.names = ["Yehuda", "Tom"];
+ ```
+
+ ```handlebars
+ {{view Ember.Select contentBinding="App.names"}}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <select class="ember-select">
+ <option value="Yehuda">Yehuda</option>
+ <option value="Tom">Tom</option>
+ </select>
+ ```
+
+ You can control which `<option>` is selected through the `Ember.Select`'s
+ `value` property directly or as a binding:
+
+ ```javascript
+ App.names = Ember.Object.create({
+ selected: 'Tom',
+ content: ["Yehuda", "Tom"]
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ contentBinding="App.names.content"
+ valueBinding="App.names.selected"
+ }}
+ ```
+
+ Would result in the following HTML with the `<option>` for 'Tom' selected:
+
+ ```html
+ <select class="ember-select">
+ <option value="Yehuda">Yehuda</option>
+ <option value="Tom" selected="selected">Tom</option>
+ </select>
+ ```
+
+ A user interacting with the rendered `<select>` to choose "Yehuda" would
+ update the value of `App.names.selected` to "Yehuda".
+
+ ### `content` as an Array of Objects
+
+ An `Ember.Select` can also take an array of JavaScript or Ember objects as
+ its `content` property.
+
+ When using objects you need to tell the `Ember.Select` which property should
+ be accessed on each object to supply the `value` attribute of the `<option>`
+ and which property should be used to supply the element text.
+
+ The `optionValuePath` option is used to specify the path on each object to
+ the desired property for the `value` attribute. The `optionLabelPath`
+ specifies the path on each object to the desired property for the
+ element's text. Both paths must reference each object itself as `content`:
+
+ ```javascript
+ App.programmers = [
+ Ember.Object.create({firstName: "Yehuda", id: 1}),
+ Ember.Object.create({firstName: "Tom", id: 2})
+ ];
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ contentBinding="App.programmers"
+ optionValuePath="content.id"
+ optionLabelPath="content.firstName"}}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <select class="ember-select">
+ <option value>Please Select</option>
+ <option value="1">Yehuda</option>
+ <option value="2">Tom</option>
+ </select>
+ ```
+
+ The `value` attribute of the selected `<option>` within an `Ember.Select`
+ can be bound to a property on another object by providing a
+ `valueBinding` option:
+
+ ```javascript
+ App.programmers = [
+ Ember.Object.create({firstName: "Yehuda", id: 1}),
+ Ember.Object.create({firstName: "Tom", id: 2})
+ ];
+
+ App.currentProgrammer = Ember.Object.create({
+ id: 2
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ contentBinding="App.programmers"
+ optionValuePath="content.id"
+ optionLabelPath="content.firstName"
+ valueBinding="App.currentProgrammer.id"}}
+ ```
+
+ Would result in the following HTML with a selected option:
+
+ ```html
+ <select class="ember-select">
+ <option value>Please Select</option>
+ <option value="1">Yehuda</option>
+ <option value="2" selected="selected">Tom</option>
+ </select>
+ ```
+
+ Interacting with the rendered element by selecting the first option
+ ('Yehuda') will update the `id` value of `App.currentProgrammer`
+ to match the `value` property of the newly selected `<option>`.
+
+ Alternatively, you can control selection through the underlying objects
+ used to render each object providing a `selectionBinding`. When the selected
+ `<option>` is changed, the property path provided to `selectionBinding`
+ will be updated to match the content object of the rendered `<option>`
+ element:
+
+ ```javascript
+ App.controller = Ember.Object.create({
+ selectedPerson: null,
+ content: [
+ Ember.Object.create({firstName: "Yehuda", id: 1}),
+ Ember.Object.create({firstName: "Tom", id: 2})
+ ]
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ contentBinding="App.controller.content"
+ optionValuePath="content.id"
+ optionLabelPath="content.firstName"
+ selectionBinding="App.controller.selectedPerson"}}
+ ```
+
+ Would result in the following HTML with a selected option:
+
+ ```html
+ <select class="ember-select">
+ <option value>Please Select</option>
+ <option value="1">Yehuda</option>
+ <option value="2" selected="selected">Tom</option>
+ </select>
+ ```
+
+ Interacting with the rendered element by selecting the first option
+ ('Yehuda') will update the `selectedPerson` value of `App.controller`
+ to match the content object of the newly selected `<option>`. In this
+ case it is the first object in the `App.content.content`
+
+ ### Supplying a Prompt
+
+ A `null` value for the `Ember.Select`'s `value` or `selection` property
+ results in there being no `<option>` with a `selected` attribute:
+
+ ```javascript
+ App.controller = Ember.Object.create({
+ selected: null,
+ content: [
+ "Yehuda",
+ "Tom"
+ ]
+ });
+ ```
+
+ ``` handlebars
+ {{view Ember.Select
+ contentBinding="App.controller.content"
+ valueBinding="App.controller.selected"
+ }}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <select class="ember-select">
+ <option value="Yehuda">Yehuda</option>
+ <option value="Tom">Tom</option>
+ </select>
+ ```
+
+ Although `App.controller.selected` is `null` and no `<option>`
+ has a `selected` attribute the rendered HTML will display the
+ first item as though it were selected. You can supply a string
+ value for the `Ember.Select` to display when there is no selection
+ with the `prompt` option:
+
+ ```javascript
+ App.controller = Ember.Object.create({
+ selected: null,
+ content: [
+ "Yehuda",
+ "Tom"
+ ]
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ contentBinding="App.controller.content"
+ valueBinding="App.controller.selected"
+ prompt="Please select a name"
+ }}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <select class="ember-select">
+ <option>Please select a name</option>
+ <option value="Yehuda">Yehuda</option>
+ <option value="Tom">Tom</option>
+ </select>
+ ```

+ ```html
+ <div class="ember-view">
+ <div data-ember-action="1">
+ click me
+ </div>
+ </div>
+ ```
+
+ Clicking "click me" will trigger the `anActionName` method of the
+ `AController`. In this case, no additional parameters will be passed.
+
+ If you provide additional parameters to the helper:
+
+ ```handlebars
+ <button {{action 'edit' post}}>Edit</button>
+ ```
+
+ Those parameters will be passed along as arguments to the JavaScript
+ function implementing the action.
+
+ ### Event Propagation
+
+ Events triggered through the action helper will automatically have
+ `.preventDefault()` called on them. You do not need to do so in your event
+ handlers.
+
+ To also disable bubbling, pass `bubbles=false` to the helper:
+
+ ```handlebars
+ <button {{action 'edit' post bubbles=false}}>Edit</button>
+ ```
+
+ If you need the default handler to trigger you should either register your
+ own event handler, or use event methods on your view class. See `Ember.View`
+ 'Responding to Browser Events' for more information.
+
+ ### Specifying DOM event type
+
+ By default the `{{action}}` helper registers for DOM `click` events. You can
+ supply an `on` option to the helper to specify a different DOM event name:
+
+ ```handlebars
+ <script type="text/x-handlebars" data-template-name='a-template'>
+ <div {{action anActionName on="doubleClick"}}>
+ click me
+ </div>
+ </script>
+ ```
+
+ See `Ember.View` 'Responding to Browser Events' for a list of
+ acceptable DOM event names.
+
+ NOTE: Because `{{action}}` depends on Ember's event dispatch system it will
+ only function if an `Ember.EventDispatcher` instance is available. An
+ `Ember.EventDispatcher` instance will be created when a new `Ember.Application`
+ is created. Having an instance of `Ember.Application` will satisfy this
+ requirement.
+
+ ### Specifying a Target
+
+ There are several possible target objects for `{{action}}` helpers:
+
+ In a typical Ember application, where views are managed through use of the
+ `{{outlet}}` helper, actions will bubble to the current controller, then
+ to the current route, and then up the route hierarchy.
+
+ Alternatively, a `target` option can be provided to the helper to change
+ which object will receive the method call. This option must be a path
+ path to an object, accessible in the current context:
+
+ ```handlebars
+ <script type="text/x-handlebars" data-template-name='a-template'>
+ <div {{action anActionName target="MyApplication.someObject"}}>
+ click me
+ </div>
+ </script>
+ ```
+
+ Clicking "click me" in the rendered HTML of the above template will trigger
+ the `anActionName` method of the object at `MyApplication.someObject`.
+
+ If an action's target does not implement a method that matches the supplied
+ action name an error will be thrown.
+
+ ```handlebars
+ <script type="text/x-handlebars" data-template-name='a-template'>
+ <div {{action aMethodNameThatIsMissing}}>
+ click me
+ </div>
+ </script>
+ ```
+
+ With the following application code
+
+ ```javascript
+ AView = Ember.View.extend({
+ templateName; 'a-template',
+ // note: no method 'aMethodNameThatIsMissing'
+ anActionName: function(event) {}
+ });
+
+ aView = AView.create();
+ aView.appendTo('body');
+ ```
+
+ Will throw `Uncaught TypeError: Cannot call method 'call' of undefined` when
+ "click me" is clicked.
+
+ ### Additional Parameters
+
+ You may specify additional parameters to the `{{action}}` helper. These
+ parameters are passed along as the arguments to the JavaScript function
+ implementing the action.
+
+ ```handlebars
+ <script type="text/x-handlebars" data-template-name='a-template'>
+ {{#each person in people}}
+ <div {{action edit person}}>
+ click me
+ </div>
+ {{/each}}
+ </script>
+ ```
+
+ Clicking "click me" will trigger the `edit` method on the current view's
+ controller with the current person as a parameter.

+/**
+ An instance of `Ember.Application` is the starting point for every Ember
+ application. It helps to instantiate, initialize and coordinate the many
+ objects that make up your app.
+
+ Each Ember app has one and only one `Ember.Application` object. In fact, the
+ very first thing you should do in your application is create the instance:
+
+ ```javascript
+ window.App = Ember.Application.create();
+ ```
+
+ Typically, the application object is the only global variable. All other
+ classes in your app should be properties on the `Ember.Application` instance,
+ which highlights its first role: a global namespace.
+
+ For example, if you define a view class, it might look like this:
+
+ ```javascript
+ App.MyView = Ember.View.extend();
+ ```
+
+ By default, calling `Ember.Application.create()` will automatically initialize
+ your application by calling the `Ember.Application.initialize()` method. If
+ you need to delay initialization, you can call your app's `deferReadiness()`
+ method. When you are ready for your app to be initialized, call its
+ `advanceReadiness()` method.
+
+ Because `Ember.Application` inherits from `Ember.Namespace`, any classes
+ you create will have useful string representations when calling `toString()`.
+ See the `Ember.Namespace` documentation for more information.
+
+ While you can think of your `Ember.Application` as a container that holds the
+ other classes in your application, there are several other responsibilities
+ going on under-the-hood that you may want to understand.
+
+ ### Event Delegation
+
+ Ember uses a technique called _event delegation_. This allows the framework
+ to set up a global, shared event listener instead of requiring each view to
+ do it manually. For example, instead of each view registering its own
+ `mousedown` listener on its associated element, Ember sets up a `mousedown`
+ listener on the `body`.
+
+ If a `mousedown` event occurs, Ember will look at the target of the event and
+ start walking up the DOM node tree, finding corresponding views and invoking
+ their `mouseDown` method as it goes.
+
+ `Ember.Application` has a number of default events that it listens for, as
+ well as a mapping from lowercase events to camel-cased view method names. For
+ example, the `keypress` event causes the `keyPress` method on the view to be
+ called, the `dblclick` event causes `doubleClick` to be called, and so on.
+
+ If there is a browser event that Ember does not listen for by default, you
+ can specify custom events and their corresponding view method names by
+ setting the application's `customEvents` property:
+
+ ```javascript
+ App = Ember.Application.create({
+ customEvents: {
+ // add support for the loadedmetadata media
+ // player event
+ 'loadedmetadata': "loadedMetadata"
+ }
+ });
+ ```
+
+ By default, the application sets up these event listeners on the document
+ body. However, in cases where you are embedding an Ember application inside
+ an existing page, you may want it to set up the listeners on an element
+ inside the body.
+
+ For example, if only events inside a DOM element with the ID of `ember-app`
+ should be delegated, set your application's `rootElement` property:
+
+ ```javascript
+ window.App = Ember.Application.create({
+ rootElement: '#ember-app'
+ });
+ ```
+
+ The `rootElement` can be either a DOM element or a jQuery-compatible selector
+ string. Note that *views appended to the DOM outside the root element will
+ not receive events.* If you specify a custom root element, make sure you only
+ append views inside it!
+
+ To learn more about the advantages of event delegation and the Ember view
+ layer, and a list of the event listeners that are setup by default, visit the
+ [Ember View Layer guide](http://emberjs.com/guides/view_layer#toc_event-delegation).
+
+ ### Initializers
+
+ Libraries on top of Ember can register additional initializers, like so:
+
+ ```javascript
+ Ember.Application.initializer({
+ name: "store",
+
+ initialize: function(container, application) {
+ container.register('store', 'main', application.Store);
+ }
+ });
+ ```
+
+ ### Routing
+
+ In addition to creating your application's router, `Ember.Application` is
+ also responsible for telling the router when to start routing. Transitions
+ between routes can be logged with the LOG_TRANSITIONS flag:
+
+ ```javascript
+ window.App = Ember.Application.create({
+ LOG_TRANSITIONS: true
+ });
+ ```
+
+ By default, the router will begin trying to translate the current URL into
+ application state once the browser emits the `DOMContentReady` event. If you
+ need to defer routing, you can call the application's `deferReadiness()`
+ method. Once routing can begin, call the `advanceReadiness()` method.
+
+ If there is any setup required before routing begins, you can implement a
+ `ready()` method on your app that will be invoked immediately before routing
+ begins.
+
+ To begin routing, you must have at a minimum a top-level controller and view.
+ You define these as `App.ApplicationController` and `App.ApplicationView`,
+ respectively. Your application will not work if you do not define these two
+ mandatory classes. For example:
+
+ ```javascript
+ App.ApplicationView = Ember.View.extend({
+ templateName: 'application'
+ });
+ App.ApplicationController = Ember.Controller.extend();
+ ```
+
+ @class Application
+ @namespace Ember
+ @extends Ember.Namespace
+*/
+var Application = Ember.Application = Ember.Namespace.extend({
+
+ /**
+ The root DOM element of the Application. This can be specified as an
+ element or a
+ [jQuery-compatible selector string](http://api.jquery.com/category/selectors/).
+
+ This is the element that will be passed to the Application's,

+/**
+ StateManager is part of Ember's implementation of a finite state machine. A
+ StateManager instance manages a number of properties that are instances of
+ `Ember.State`,
+ tracks the current active state, and triggers callbacks when states have changed.
+
+ ## Defining States
+
+ The states of StateManager can be declared in one of two ways. First, you can
+ define a `states` property that contains all the states:
+
+ ```javascript
+ managerA = Ember.StateManager.create({
+ states: {
+ stateOne: Ember.State.create(),
+ stateTwo: Ember.State.create()
+ }
+ })
+
+ managerA.get('states')
+ // {
+ // stateOne: Ember.State.create(),
+ // stateTwo: Ember.State.create()
+ // }
+ ```
+
+ You can also add instances of `Ember.State` (or an `Ember.State` subclass)
+ directly as properties of a StateManager. These states will be collected into
+ the `states` property for you.
+
+ ```javascript
+ managerA = Ember.StateManager.create({
+ stateOne: Ember.State.create(),
+ stateTwo: Ember.State.create()
+ })
+
+ managerA.get('states')
+ // {
+ // stateOne: Ember.State.create(),
+ // stateTwo: Ember.State.create()
+ // }
+ ```
+
+ ## The Initial State
+
+ When created a StateManager instance will immediately enter into the state
+ defined as its `start` property or the state referenced by name in its
+ `initialState` property:
+
+ ```javascript
+ managerA = Ember.StateManager.create({
+ start: Ember.State.create({})
+ })
+
+ managerA.get('currentState.name') // 'start'
+
+ managerB = Ember.StateManager.create({
+ initialState: 'beginHere',
+ beginHere: Ember.State.create({})
+ })
+
+ managerB.get('currentState.name') // 'beginHere'
+ ```
+
+ Because it is a property you may also provide a computed function if you wish
+ to derive an `initialState` programmatically:
+
+ ```javascript
+ managerC = Ember.StateManager.create({
+ initialState: function(){
+ if (someLogic) {
+ return 'active';
+ } else {
+ return 'passive';
+ }
+ }.property(),
+ active: Ember.State.create({}),
+ passive: Ember.State.create({})
+ })
+ ```
+
+ ## Moving Between States
+
+ A StateManager can have any number of `Ember.State` objects as properties
+ and can have a single one of these states as its current state.
+
+ Calling `transitionTo` transitions between states:
+
+ ```javascript
+ robotManager = Ember.StateManager.create({
+ initialState: 'poweredDown',
+ poweredDown: Ember.State.create({}),
+ poweredUp: Ember.State.create({})
+ })
+
+ robotManager.get('currentState.name') // 'poweredDown'
+ robotManager.transitionTo('poweredUp')
+ robotManager.get('currentState.name') // 'poweredUp'
+ ```
+
+ Before transitioning into a new state the existing `currentState` will have
+ its `exit` method called with the StateManager instance as its first argument
+ and an object representing the transition as its second argument.
+
+ After transitioning into a new state the new `currentState` will have its
+ `enter` method called with the StateManager instance as its first argument
+ and an object representing the transition as its second argument.
+
+ ```javascript
+ robotManager = Ember.StateManager.create({
+ initialState: 'poweredDown',
+ poweredDown: Ember.State.create({
+ exit: function(stateManager){
+ console.log("exiting the poweredDown state")
+ }
+ }),
+ poweredUp: Ember.State.create({
+ enter: function(stateManager){
+ console.log("entering the poweredUp state. Destroy all humans.")
+ }
+ })
+ })
+
+ robotManager.get('currentState.name') // 'poweredDown'
+ robotManager.transitionTo('poweredUp')
+
+ // will log
+ // 'exiting the poweredDown state'
+ // 'entering the poweredUp state. Destroy all humans.'
+ ```
+
+ Once a StateManager is already in a state, subsequent attempts to enter that
+ state will not trigger enter or exit method calls. Attempts to transition
+ into a state that the manager does not have will result in no changes in the
+ StateManager's current state:
+
+ ```javascript
+ robotManager = Ember.StateManager.create({
+ initialState: 'poweredDown',
+ poweredDown: Ember.State.create({
+ exit: function(stateManager){
+ console.log("exiting the poweredDown state")
+ }
+ }),
+ poweredUp: Ember.State.create({
+ enter: function(stateManager){
+ console.log("entering the poweredUp state. Destroy all humans.")
+ }
+ })
+ })
+
+ robotManager.get('currentState.name') // 'poweredDown'
+ robotManager.transitionTo('poweredUp')
+ // will log
+ // 'exiting the poweredDown state'
+ // 'entering the poweredUp state. Destroy all humans.'
+ robotManager.transitionTo('poweredUp') // no logging, no state change
+
+ robotManager.transitionTo('someUnknownState') // silently fails
+ robotManager.get('currentState.name') // 'poweredUp'
+ ```
+
+ Each state property may itself contain properties that are instances of
+ `Ember.State`. The StateManager can transition to specific sub-states in a
+ series of transitionTo method calls or via a single transitionTo with the
+ full path to the specific state. The StateManager will also keep track of the
+ full path to its currentState
+
+ ```javascript
+ robotManager = Ember.StateManager.create({
+ initialState: 'poweredDown',
+ poweredDown: Ember.State.create({
+ charging: Ember.State.create(),
+ charged: Ember.State.create()
+ }),
+ poweredUp: Ember.State.create({
+ mobile: Ember.State.create(),
+ stationary: Ember.State.create()
+ })
+ })
+
+ robotManager.get('currentState.name') // 'poweredDown'
+
+ robotManager.transitionTo('poweredUp')
+ robotManager.get('currentState.name') // 'poweredUp'
+
+ robotManager.transitionTo('mobile')
+ robotManager.get('currentState.name') // 'mobile'
+
+ // transition via a state path
+ robotManager.transitionTo('poweredDown.charging')
+ robotManager.get('currentState.name') // 'charging'
+
+ robotManager.get('currentState.path') // 'poweredDown.charging'
+ ```
+
+ Enter transition methods will be called for each state and nested child state
+ in their hierarchical order. Exit methods will be called for each state and
+ its nested states in reverse hierarchical order.
+
+ Exit transitions for a parent state are not called when entering into one of
+ its child states, only when transitioning to a new section of possible states
+ in the hierarchy.
+
+ ```javascript
+ robotManager = Ember.StateManager.create({
+ initialState: 'poweredDown',
+ poweredDown: Ember.State.create({
+ enter: function(){},
+ exit: function(){
+ console.log("exited poweredDown state")
+ },
+ charging: Ember.State.create({
+ enter: function(){},
+ exit: function(){}
+ }),
+ charged: Ember.State.create({
+ enter: function(){
+ console.log("entered charged state")
+ },
+ exit: function(){
+ console.log("exited charged state")
+ }
+ })
+ }),
+ poweredUp: Ember.State.create({
+ enter: function(){
+ console.log("entered poweredUp state")
+ },
+ exit: function(){},
+ mobile: Ember.State.create({
+ enter: function(){
+ console.log("entered mobile state")
+ },
+ exit: function(){}
+ }),
+ stationary: Ember.State.create({
+ enter: function(){},
+ exit: function(){}
+ })
+ })
+ })
+
+
+ robotManager.get('currentState.path') // 'poweredDown'
+ robotManager.transitionTo('charged')
+ // logs 'entered charged state'
+ // but does *not* log 'exited poweredDown state'
+ robotManager.get('currentState.name') // 'charged
+
+ robotManager.transitionTo('poweredUp.mobile')
+ // logs
+ // 'exited charged state'
+ // 'exited poweredDown state'
+ // 'entered poweredUp state'
+ // 'entered mobile state'
+ ```
+
+ During development you can set a StateManager's `enableLogging` property to
+ `true` to receive console messages of state transitions.
+
+ ```javascript
+ robotManager = Ember.StateManager.create({
+ enableLogging: true
+ })
+ ```
+
+ ## Managing currentState with Actions
+
+ To control which transitions are possible for a given state, and
+ appropriately handle external events, the StateManager can receive and
+ route action messages to its states via the `send` method. Calling to
+ `send` with an action name will begin searching for a method with the same
+ name starting at the current state and moving up through the parent states
+ in a state hierarchy until an appropriate method is found or the StateManager
+ instance itself is reached.
+
+ If an appropriately named method is found it will be called with the state
+ manager as the first argument and an optional `context` object as the second
+ argument.
+
+ ```javascript
+ managerA = Ember.StateManager.create({
+ initialState: 'stateOne.substateOne.subsubstateOne',
+ stateOne: Ember.State.create({
+ substateOne: Ember.State.create({
+ anAction: function(manager, context){
+ console.log("an action was called")
+ },
+ subsubstateOne: Ember.State.create({})
+ })
+ })
+ })
+
+ managerA.get('currentState.name') // 'subsubstateOne'
+ managerA.send('anAction')
+ // 'stateOne.substateOne.subsubstateOne' has no anAction method
+ // so the 'anAction' method of 'stateOne.substateOne' is called
+ // and logs "an action was called"
+ // with managerA as the first argument
+ // and no second argument
+
+ someObject = {}
+ managerA.send('anAction', someObject)
+ // the 'anAction' method of 'stateOne.substateOne' is called again
+ // with managerA as the first argument and
+ // someObject as the second argument.
+ ```
+
+ If the StateManager attempts to send an action but does not find an appropriately named
+ method in the current state or while moving upwards through the state hierarchy, it will
+ repeat the process looking for a `unhandledEvent` method. If an `unhandledEvent` method is
+ found, it will be called with the original event name as the second argument. If an
+ `unhandledEvent` method is not found, the StateManager will throw a new Ember.Error.
+
+ ```javascript
+ managerB = Ember.StateManager.create({
+ initialState: 'stateOne.substateOne.subsubstateOne',
+ stateOne: Ember.State.create({
+ substateOne: Ember.State.create({
+ subsubstateOne: Ember.State.create({}),
+ unhandledEvent: function(manager, eventName, context) {
+ console.log("got an unhandledEvent with name " + eventName);
+ }
+ })
+ })
+ })
+
+ managerB.get('currentState.name') // 'subsubstateOne'
+ managerB.send('anAction')
+ // neither `stateOne.substateOne.subsubstateOne` nor any of it's
+ // parent states have a handler for `anAction`. `subsubstateOne`
+ // also does not have a `unhandledEvent` method, but its parent
+ // state, `substateOne`, does, and it gets fired. It will log
+ // "got an unhandledEvent with name anAction"
+ ```
+
+ Action detection only moves upwards through the state hierarchy from the current state.
+ It does not search in other portions of the hierarchy.
+
+ ```javascript
+ managerC = Ember.StateManager.create({
+ initialState: 'stateOne.substateOne.subsubstateOne',
+ stateOne: Ember.State.create({
+ substateOne: Ember.State.create({
+ subsubstateOne: Ember.State.create({})
+ })
+ }),
+ stateTwo: Ember.State.create({
+ anAction: function(manager, context){
+ // will not be called below because it is
+ // not a parent of the current state
+ }
+ })
+ })
+
+ managerC.get('currentState.name') // 'subsubstateOne'
+ managerC.send('anAction')
+ // Error: <Ember.StateManager:ember132> could not
+ // respond to event anAction in state stateOne.substateOne.subsubstateOne.
+ ```
+
+ Inside of an action method the given state should delegate `transitionTo` calls on its
+ StateManager.
+
+ ```javascript
+ robotManager = Ember.StateManager.create({
+ initialState: 'poweredDown.charging',
+ poweredDown: Ember.State.create({
+ charging: Ember.State.create({
+ chargeComplete: function(manager, context){
+ manager.transitionTo('charged')
+ }
+ }),
+ charged: Ember.State.create({
+ boot: function(manager, context){
+ manager.transitionTo('poweredUp')
+ }
+ })
+ }),
+ poweredUp: Ember.State.create({
+ beginExtermination: function(manager, context){
+ manager.transitionTo('rampaging')
+ },
+ rampaging: Ember.State.create()
+ })
+ })
+
+ robotManager.get('currentState.name') // 'charging'
+ robotManager.send('boot') // throws error, no boot action
+ // in current hierarchy
+ robotManager.get('currentState.name') // remains 'charging'
+
+ robotManager.send('beginExtermination') // throws error, no beginExtermination
+ // action in current hierarchy
+ robotManager.get('currentState.name') // remains 'charging'
+
+ robotManager.send('chargeComplete')
+ robotManager.get('currentState.name') // 'charged'
+
+ robotManager.send('boot')
+ robotManager.get('currentState.name') // 'poweredUp'
+
+ robotManager.send('beginExtermination', allHumans)
+ robotManager.get('currentState.name') // 'rampaging'
+ ```
+
+ Transition actions can also be created using the `transitionTo` method of the `Ember.State` class. The
+ following example StateManagers are equivalent:
+
+ ```javascript
+ aManager = Ember.StateManager.create({
+ stateOne: Ember.State.create({
+ changeToStateTwo: Ember.State.transitionTo('stateTwo')
+ }),
+ stateTwo: Ember.State.create({})
+ })
+
+ bManager = Ember.StateManager.create({
+ stateOne: Ember.State.create({
+ changeToStateTwo: function(manager, context){
+ manager.transitionTo('stateTwo', context)
+ }
+ }),
+ stateTwo: Ember.State.create({})
+ })
+ ```
