Also, - * the [mvc.model Get Started with jQueryMX] has a good walkthrough of $.Model. - * - * - * ## Get and modify data from the server - * - * $.Model makes connecting to a JSON REST service - * really easy. The following models todos by - * describing the services that can create, retrieve, - * update, and delete todos. - * - * $.Model('Todo',{ - * findAll: 'GET /todos.json', - * findOne: 'GET /todos/{id}.json', - * create: 'POST /todos.json', - * update: 'PUT /todos/{id}.json', - * destroy: 'DELETE /todos/{id}.json' - * },{}); - * - * This lets you create, retrieve, update, and delete - * todos programatically: - * - * __Create__ - * - * Create a todo instance and - * call [jQuery.Model.prototype.save save]( success, error ) - * to create the todo on the server. - * - * // create a todo instance - * var todo = new Todo({name: "do the dishes"}) - * - * // save it on the server - * todo.save(); - * - * __Retrieve__ - * - * Retrieve a list of todos from the server with - * findAll( params, callback( items ) ): - * - * Todo.findAll({}, function( todos ){ - * - * // print out the todo names - * $.each(todos, function(i, todo){ - * console.log( todo.name ); - * }); - * }); - * - * Retrieve a single todo from the server with - * findOne( params, callback( item ) ): - * - * Todo.findOne({id: 5}, function( todo ){ - * - * // print out the todo name - * console.log( todo.name ); - * }); - * - * __Update__ - * - * Once an item has been created on the server, - * you can change its properties and call - * save to update it on the server. - * - * // update the todos' name - * todo.attr('name','Take out the trash') - * - * // update it on the server - * todo.save() - * - * - * __Destroy__ - * - * Call [jQuery.Model.prototype.destroy destroy]( success, error ) - * to delete an item on the server. - * - * todo.destroy() - * - * ## Listen to changes in data - * - * Listening to changes in data is a critical part of - * the [http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller Model-View-Controller] - * architecture. $.Model lets you listen to when an item is created, updated, destroyed - * and its properties are changed by creating [jquery.model.events events] - * on the Model and on instances of the model. - * - * __Create__ - * - * // listen for when any todo is created - * Todo.bind('created', function( ev, todo ) {...}) - * - * // listen for when a specific todo is created - * var todo = new Todo({name: 'do dishes'}) - * todo.bind('created', function( ev ) {...}) - * - * __Update__ - * - * // listen for when any todo is updated - * Todo.bind('updated', function( ev, todo ) {...}) - * - * // listen for when a specific todo is created - * Todo.findOne({id: 6}, function( todo ) { - * todo.bind('updated', function( ev ) {...}) - * }) - * - * __Destroy__ - * - * // listen for when any todo is destroyed - * Todo.bind('destroyed', function( ev, todo ) {...}) - * - * // listen for when a specific todo is destroyed - * todo.bind('destroyed', function( ev ) {...}) - * - * __Property Changes__ - * - * // listen for when the name property changes - * todo.bind('name', function(ev){ }) - * - * __Listening with Controller__ - * - * You should be using controller to listen to model changes like: - * - * $.Controller('Todos',{ - * "{Todo} updated" : function(Todo, ev, todo) {...} - * }) - * - * - * ## Setting and retrieving data on elements - * - * Almost always, we use HTMLElements to represent - * data to the user. When that data changes, we update those - * elements to reflect the new data. - * - * $.Model has helper methods that make this easy. They - * let you "add" a model to an element and also find - * all elements that have had a model "added" to them. - * - * Consider a todo list widget - * that lists each todo in the page and when a todo is - * deleted, removes it. - * - * [jQuery.fn.model $.fn.model]( item ) lets you set or read a model - * instance from an element: - * - * Todo.findAll({}, function( todos ) { - * - * $.each(todos, function(todo) { - * $('

').model(todo) - * .text(todo.name) - * .appendTo('#todos') - * }); - * }); - * - * When a todo is deleted, get its element with - * item.[jQuery.Model.prototype.elements elements]( context ) - * and remove it from the page. - * - * Todo.bind('destroyed', function( ev, todo ) { - * todo.elements( $('#todos') ).remove() - * }) - * - * __Using EJS and $.Controller__ - * - * [jQuery.View $.View] and [jQuery.EJS EJS] makes adding model data - * to elements easy. We can implement the todos widget like the following: - * - * $.Controller('Todos',{ - * init: function(){ - * this.element.html('//todos/views/todos.ejs', Todo.findAll({}) ); - * }, - * "{Todo} destroyed": function(Todo, ev, todo) { - * todo.elements( this.element ).remove() - * } - * }) - * - * In todos.ejs - * - * @codestart html - * <% for(var i =0; i < todos.length; i++){ %> - * <li <%= todos[i] %>><%= todos[i].name %></li> - * <% } %> - * @codeend - * - * Notice how you can add a model to an element with <%= model %> - * - * ## Lists - * - * [jQuery.Model.List $.Model.List] lets you handle multiple model instances - * with ease. A List acts just like an Array, but you can add special properties - * to it and listen to events on it. - * - * $.Model.List has become its own plugin, read about it - * [jQuery.Model.List here]. - * - * ## Other Good Stuff - * - * Model can make a lot of other common tasks much easier. - * - * ### Type Conversion - * - * Data from the server often needs massaging to make it more useful - * for JavaScript. A typical example is date data which is - * commonly passed as - * a number representing the Julian date like: - * - * { name: 'take out trash', - * id: 1, - * dueDate: 1303173531164 } - * - * But instead, you want a JavaScript date object: - * - * date.attr('dueDate') //-> new Date(1303173531164) - * - * By defining property-type pairs in [jQuery.Model.static.attributes attributes], - * you can have model auto-convert values from the server into more useful types: - * - * $.Model('Todo',{ - * attributes : { - * dueDate: 'date' - * } - * },{}) - * - * ### Associations - * - * The [jQuery.Model.static.attributes attributes] property also - * supports associations. For example, todo data might come back with - * User data as an owner property like: - * - * { name: 'take out trash', - * id: 1, - * owner: { name: 'Justin', id: 3} } - * - * To convert owner into a User model, set the owner type as the User's - * [jQuery.Model.static.model model]( data ) method: - * - * $.Model('Todo',{ - * attributes : { - * owner: 'User.model' - * } - * },{}) - * - * ### Helper Functions - * - * Often, you need to perform repeated calculations - * with a model's data. You can create methods in the model's - * prototype and they will be available on - * all model instances. - * - * The following creates a timeRemaining method that - * returns the number of seconds left to complete the todo: - * - * $.Model('Todo',{ - * },{ - * timeRemaining : function(){ - * return new Date() - new Date(this.dueDate) - * } - * }) - * - * // create a todo - * var todo = new Todo({dueDate: new Date()}); - * - * // show off timeRemaining - * todo.timeRemaining() //-> Number - * - * ### Deferreds - * - * Model methods that make requests to the server such as: - * [jQuery.Model.static.findAll findAll], [jQuery.Model.static.findOne findOne], - * [jQuery.Model.prototype.save save], and [jQuery.Model.prototype.destroy destroy] return a - * [jquery.model.deferreds deferred] that resolves to the item(s) - * being retrieved or modified. - * - * Deferreds can make a lot of asynchronous code much easier. For example, the following - * waits for all users and tasks before continuing : - * - * $.when(Task.findAll(), User.findAll()) - * .then(function( tasksRes, usersRes ){ ... }) - * - * ### Validations - * - * [jquery.model.validations Validate] your model's attributes. - * - * $.Model("Contact",{ - * init : function(){ - * this.validate("birthday",function(){ - * if(this.birthday > new Date){ - * return "your birthday needs to be in the past" - * } - * }) - * } - * ,{}); - * - * - */ - // methods that we'll weave into model if provided - ajaxMethods = - /** - * @Static - */ - { - create: function( str ) { - /** - * @function create - * Create is used to create a model instance on the server.

You just need to call success back with - * an object that contains the id of the new instance and any other properties that should be - * set on the instance. - * - * For example, the following code makes a request - * to '/recipes.json?name=hot+dog' and gets back - * something that looks like: - * - * { - * id: 5, - * createdAt: 2234234329 - * } - * - * The code looks like: - * - * $.Model("Recipe", { - * create : function(attrs, success, error){ - * $.post("/recipes.json",attrs, success,"json"); - * } - * },{}) - * - * - * @param {Object} attrs Attributes on the model instance - * @param {Function} success(attrs) the callback function, it must be called with an object - * that has the id of the new instance and any other attributes the service needs to add. - * @param {Function} error a function to callback if something goes wrong. - */ - return function( attrs, success, error ) { - return ajax(str || this._shortName, attrs, success, error, fixture(this, "Create", "-restCreate")) - }; - }, - update: function( str ) { - /** - * @function update - * Update is used to update a model instance on the server.

For example if your server udpates the "updatedAt" property, it - * should send back something like: - * - * // PUT /recipes/4 {name: "Food"} -> - * { - * updatedAt : "10-20-2011" - * } - * - * You can also implement create by yourself.

Introspection

- * - * Often, it's nice to create classes whose name helps determine functionality. Ruby on - * Rails's [http://api.rubyonrails.org/classes/ActiveRecord/Base.html|ActiveRecord] ORM class - * is a great example of this. Unfortunately, JavaScript doesn't have a way of determining - * an object's name, so the developer must provide a name. Class fixes this by taking a String name for the class. - * - * $.Class("MyOrg.MyClass",{},{}) - * MyOrg.MyClass.shortName //-> 'MyClass' - * MyOrg.MyClass.fullName //-> 'MyOrg.MyClass' - * - * The fullName (with namespaces) and the shortName (without namespaces) are added to the Class's - * static properties. - * - * - * ## Setup and initialization methods - * - *

- * Class provides static and prototype initialization functions. - * These come in two flavors - setup and init. - * Setup is called before init and - * can be used to 'normalize' init's arguments. - *

- *

PRO TIP: Typically, you don't need setup methods in your classes. Use Init instead. - * Reserve setup methods for when you need to do complex pre-processing of your class before init is called. - * - *

- * @codestart - * $.Class("MyClass", - * { - * setup: function() {} //static setup - * init: function() {} //static constructor - * }, - * { - * setup: function() {} //prototype setup - * init: function() {} //prototype constructor - * }) - * @codeend - * - * ### Setup - * - * Setup functions are called before init functions. Static setup functions are passed - * the base class followed by arguments passed to the extend function. - * Prototype static functions are passed the Class constructor - * function arguments. - * - * If a setup function returns an array, that array will be used as the arguments - * for the following init method. This provides setup functions the ability to normalize - * arguments passed to the init constructors. They are also excellent places - * to put setup code you want to almost always run. - * - * - * The following is similar to how [jQuery.Controller.prototype.setup] - * makes sure init is always called with a jQuery element and merged options - * even if it is passed a raw - * HTMLElement and no second parameter. - * - * $.Class("jQuery.Controller",{ - * ... - * },{ - * setup: function( el, options ) { - * ... - * return [$(el), - * $.extend(true, - * this.Class.defaults, - * options || {} ) ] - * } - * }) - * - * Typically, you won't need to make or overwrite setup functions. - * - * ### Init - * - * Init functions are called after setup functions. - * Typically, they receive the same arguments - * as their preceding setup function. The Foo class's init method - * gets called in the following example: - * - * $.Class("Foo", { - * init: function( arg1, arg2, arg3 ) { - * this.sum = arg1+arg2+arg3; - * } - * }) - * var foo = new Foo(1,2,3); - * foo.sum //-> 6 - * - * ## Proxies - * - * Similar to jQuery's proxy method, Class provides a - * [jQuery.Class.static.proxy proxy] - * function that returns a callback to a method that will always - * have - * this set to the class or instance of the class. - * - * - * The following example uses this.proxy to make sure - * this.name is available in show. - * - * $.Class("Todo",{ - * init: function( name ) { - * this.name = name - * }, - * get: function() { - * $.get("/stuff",this.proxy('show')) - * }, - * show: function( txt ) { - * alert(this.name+txt) - * } - * }) - * new Todo("Trash").get() - * - * Callback is available as a static and prototype method. - * - * ## Demo - * - * @demo jquery/class/class.html - * - * - * @constructor - * - * To create a Class call: - * - * $.Class( [NAME , STATIC,] PROTOTYPE ) -> Class - * - *

- *

NAME{optional:String} - *

If provided, this sets the shortName and fullName of the - * class and adds it and any necessary namespaces to the - * window object.

- *

STATIC{optional:Object} - *

If provided, this creates static properties and methods - * on the class.

- *

PROTOTYPE{Object} - *

Creates prototype methods on the class.

- *

- * - * When a Class is created, the static [jQuery.Class.static.setup setup] - * and [jQuery.Class.static.init init] methods are called. - * - * To create an instance of a Class, call: - * - * new Class([args ... ]) -> instance - * - * The created instance will have all the - * prototype properties and methods defined by the PROTOTYPE object. - * - * When an instance is created, the prototype [jQuery.Class.prototype.setup setup] - * and [jQuery.Class.prototype.init init] methods - * are called. - */ - - clss = $.Class = function() { - if (arguments.length) { - return clss.extend.apply(clss, arguments); - } - }; - - /* @Static*/ - extend(clss, { - /** - * @function newInstance - * Creates a new instance of the class.

Prototype propertes are available only on instances of the Class. + * + * ## A Basic Class + * + * The following creates a Monster class with a + * name (for introspection), static, and prototype members. + * Every time a monster instance is created, the static + * count is incremented. + * + * @codestart + * $.Class('Monster', + * /* @static *| + * { + * count: 0 + * }, + * /* @prototype *| + * { + * init: function( name ) { + * + * // saves name on the monster instance + * this.name = name; + * + * // sets the health + * this.health = 10; + * + * // increments count + * this.constructor.count++; + * }, + * eat: function( smallChildren ){ + * this.health += smallChildren; + * }, + * fight: function() { + * this.health -= 2; + * } + * }); + * + * hydra = new Monster('hydra'); + * + * dragon = new Monster('dragon'); + * + * hydra.name // -> hydra + * Monster.count // -> 2 + * Monster.shortName // -> 'Monster' + * + * hydra.eat(2); // health = 12 + * + * dragon.fight(); // health = 8 + * + * @codeend + * + * + * Notice that the prototype init function is called when a new instance of Monster is created. + * + * + * ## Inheritance + * + * When a class is extended, all static and prototype properties are available on the new class. + * If you overwrite a function, you can call the base class's function by calling + * this._super. Lets create a SeaMonster class. SeaMonsters are less + * efficient at eating small children, but more powerful fighters. + * + * + * Monster("SeaMonster",{ + * eat: function( smallChildren ) { + * this._super(smallChildren / 2); + * }, + * fight: function() { + * this.health -= 1; + * } + * }); + * + * lockNess = new SeaMonster('Lock Ness'); + * lockNess.eat(4); //health = 12 + * lockNess.fight(); //health = 11 + * + * ### Static property inheritance + * + * You can also inherit static properties in the same way: + * + * $.Class("First", + * { + * staticMethod: function() { return 1;} + * },{}) + * + * First("Second",{ + * staticMethod: function() { return this._super()+1;} + * },{}) + * + * Second.staticMethod() // -> 2 + * + * ## Namespaces + * + * Namespaces are a good idea! We encourage you to namespace all of your code. + * It makes it possible to drop your code into another app without problems. + * Making a namespaced class is easy: + * + * + * $.Class("MyNamespace.MyClass",{},{}); + * + * new MyNamespace.MyClass() + * + * + *

Introspection

+ * + * Often, it's nice to create classes whose name helps determine functionality. Ruby on + * Rails's [http://api.rubyonrails.org/classes/ActiveRecord/Base.html|ActiveRecord] ORM class + * is a great example of this. Unfortunately, JavaScript doesn't have a way of determining + * an object's name, so the developer must provide a name. Class fixes this by taking a String name for the class. + * + * $.Class("MyOrg.MyClass",{},{}) + * MyOrg.MyClass.shortName //-> 'MyClass' + * MyOrg.MyClass.fullName //-> 'MyOrg.MyClass' + * + * The fullName (with namespaces) and the shortName (without namespaces) are added to the Class's + * static properties. + * + * + * ## Setup and initialization methods + * + *

+ * Class provides static and prototype initialization functions. + * These come in two flavors - setup and init. + * Setup is called before init and + * can be used to 'normalize' init's arguments. + *

+ *

PRO TIP: Typically, you don't need setup methods in your classes. Use Init instead. + * Reserve setup methods for when you need to do complex pre-processing of your class before init is called. + * + *

+ * @codestart + * $.Class("MyClass", + * { + * setup: function() {} //static setup + * init: function() {} //static constructor + * }, + * { + * setup: function() {} //prototype setup + * init: function() {} //prototype constructor + * }) + * @codeend + * + * ### Setup + * + * Setup functions are called before init functions. Static setup functions are passed + * the base class followed by arguments passed to the extend function. + * Prototype static functions are passed the Class constructor + * function arguments. + * + * If a setup function returns an array, that array will be used as the arguments + * for the following init method. This provides setup functions the ability to normalize + * arguments passed to the init constructors. They are also excellent places + * to put setup code you want to almost always run. + * + * + * The following is similar to how [jQuery.Controller.prototype.setup] + * makes sure init is always called with a jQuery element and merged options + * even if it is passed a raw + * HTMLElement and no second parameter. + * + * $.Class("jQuery.Controller",{ + * ... + * },{ + * setup: function( el, options ) { + * ... + * return [$(el), + * $.extend(true, + * this.Class.defaults, + * options || {} ) ] + * } + * }) + * + * Typically, you won't need to make or overwrite setup functions. + * + * ### Init + * + * Init functions are called after setup functions. + * Typically, they receive the same arguments + * as their preceding setup function. The Foo class's init method + * gets called in the following example: + * + * $.Class("Foo", { + * init: function( arg1, arg2, arg3 ) { + * this.sum = arg1+arg2+arg3; + * } + * }) + * var foo = new Foo(1,2,3); + * foo.sum //-> 6 + * + * ## Proxies + * + * Similar to jQuery's proxy method, Class provides a + * [jQuery.Class.static.proxy proxy] + * function that returns a callback to a method that will always + * have + * this set to the class or instance of the class. + * + * + * The following example uses this.proxy to make sure + * this.name is available in show. + * + * $.Class("Todo",{ + * init: function( name ) { + * this.name = name + * }, + * get: function() { + * $.get("/stuff",this.proxy('show')) + * }, + * show: function( txt ) { + * alert(this.name+txt) + * } + * }) + * new Todo("Trash").get() + * + * Callback is available as a static and prototype method. + * + * ## Demo + * + * @demo jquery/class/class.html + * + * + * @constructor + * + * To create a Class call: + * + * $.Class( [NAME , STATIC,] PROTOTYPE ) -> Class + * + *

+ *

NAME{optional:String} + *

If provided, this sets the shortName and fullName of the + * class and adds it and any necessary namespaces to the + * window object.

+ *

STATIC{optional:Object} + *

If provided, this creates static properties and methods + * on the class.

+ *

PROTOTYPE{Object} + *

Creates prototype methods on the class.

+ *

+ * + * When a Class is created, the static [jQuery.Class.static.setup setup] + * and [jQuery.Class.static.init init] methods are called. + * + * To create an instance of a Class, call: + * + * new Class([args ... ]) -> instance + * + * The created instance will have all the + * prototype properties and methods defined by the PROTOTYPE object. + * + * When an instance is created, the prototype [jQuery.Class.prototype.setup setup] + * and [jQuery.Class.prototype.init init] methods + * are called. + */ + + clss = $.Class = function() { + if (arguments.length) { + return clss.extend.apply(clss, arguments); + } + }; + + /* @Static*/ + extend(clss, { + /** + * @function newInstance + * Creates a new instance of the class.

Find - * more information [jquery.controller.plugin here] about the plugin gets created - * and the rules around its name. - * - * ### An instance of controller is created on an element - * - * $('.thing').my_widget(options) // calls new MyWidget(el, options) - * - * This calls new MyWidget(el, options) on - * each '.thing' element. - * - * When a new [jQuery.Class Class] instance is created, it calls the class's - * prototype setup and init methods. Controller's [jQuery.Controller.prototype.setup setup] - * method: - * - * - Sets [jQuery.Controller.prototype.element this.element] and adds the controller's name to element's className. - * - Merges passed in options with defaults object and sets it as [jQuery.Controller.prototype.options this.options] - * - Saves a reference to the controller in $.data. - * - [jquery.controller.listening Binds all event handler methods]. - * - * - * ### The controller responds to events - * - * Typically, Controller event handlers are automatically bound. However, there are - * multiple ways to [jquery.controller.listening listen to events] with a controller. - * - * Once an event does happen, the callback function is always called with 'this' - * referencing the controller instance. This makes it easy to use helper functions and - * save state on the controller. - * - * - * ### The widget is destroyed - * - * If the element is removed from the page, the - * controller's [jQuery.Controller.prototype.destroy] method is called. - * This is a great place to put any additional teardown functionality. - * - * You can also teardown a controller programatically like: - * - * $('.thing').my_widget('destroy'); - * - * ## Todos Example - * - * Lets look at a very basic example - - * a list of todos and a button you want to click to create a new todo. - * Your HTML might look like: - * - * @codestart html - * <div id='todos'> - * <ol> - * <li class="todo">Laundry</li> - * <li class="todo">Dishes</li> - * <li class="todo">Walk Dog</li> - * </ol> - * <a class="create">Create</a> - * </div> - * @codeend - * - * To add a mousover effect and create todos, your controller might look like: - * - * $.Controller('Todos',{ - * ".todo mouseover" : function( el, ev ) { - * el.css("backgroundColor","red") - * }, - * ".todo mouseout" : function( el, ev ) { - * el.css("backgroundColor","") - * }, - * ".create click" : function() { - * this.find("ol").append("<li class='todo'>New Todo</li>"); - * } - * }) - * - * Now that you've created the controller class, you've must attach the event handlers on the '#todos' div by - * creating [jQuery.Controller.prototype.setup|a new controller instance].

Use jQuery function - * $('#todos').todos(); - * @codeend - * - * ## Controller Initialization - * - * It can be extremely useful to add an init method with - * setup functionality for your widget. - * - * In the following example, I create a controller that when created, will put a message as the content of the element: - * - * $.Controller("SpecialController", - * { - * init: function( el, message ) { - * this.element.html(message) - * } - * }) - * $(".special").special("Hello World") - * - * ## Removing Controllers - * - * Controller removal is built into jQuery. So to remove a controller, you just have to remove its element: - * - * @codestart - * $(".special_controller").remove() - * $("#containsControllers").html("") - * @codeend - * - * It's important to note that if you use raw DOM methods (innerHTML, removeChild), the controllers won't be destroyed. - * - * If you just want to remove controller functionality, call destroy on the controller instance: - * - * @codestart - * $(".special_controller").controller().destroy() - * @codeend - * - * ## Accessing Controllers - * - * Often you need to get a reference to a controller, there are a few ways of doing that.

It can be used + * to build simple widgets, like a slider, or organize multiple + * widgets into something greater. + * + * To understand how to use Controller, you need to understand + * the typical lifecycle of a jQuery widget and how that maps to + * controller's functionality: + * + * ### A controller class is created. + * + * $.Controller("MyWidget", + * { + * defaults : { + * message : "Remove Me" + * } + * }, + * { + * init : function(rawEl, rawOptions){ + * this.element.append( + * "

"+this.options.message+"

" + * ); + * }, + * "div click" : function(div, ev){ + * div.remove(); + * } + * }) + * + * This creates a $.fn.my_widget jQuery helper function + * that can be used to create a new controller instance on an element. Find + * more information [jquery.controller.plugin here] about the plugin gets created + * and the rules around its name. + * + * ### An instance of controller is created on an element + * + * $('.thing').my_widget(options) // calls new MyWidget(el, options) + * + * This calls new MyWidget(el, options) on + * each '.thing' element. + * + * When a new [jQuery.Class Class] instance is created, it calls the class's + * prototype setup and init methods. Controller's [jQuery.Controller.prototype.setup setup] + * method: + * + * - Sets [jQuery.Controller.prototype.element this.element] and adds the controller's name to element's className. + * - Merges passed in options with defaults object and sets it as [jQuery.Controller.prototype.options this.options] + * - Saves a reference to the controller in $.data. + * - [jquery.controller.listening Binds all event handler methods]. + * + * + * ### The controller responds to events + * + * Typically, Controller event handlers are automatically bound. However, there are + * multiple ways to [jquery.controller.listening listen to events] with a controller. + * + * Once an event does happen, the callback function is always called with 'this' + * referencing the controller instance. This makes it easy to use helper functions and + * save state on the controller. + * + * + * ### The widget is destroyed + * + * If the element is removed from the page, the + * controller's [jQuery.Controller.prototype.destroy] method is called. + * This is a great place to put any additional teardown functionality. + * + * You can also teardown a controller programatically like: + * + * $('.thing').my_widget('destroy'); + * + * ## Todos Example + * + * Lets look at a very basic example - + * a list of todos and a button you want to click to create a new todo. + * Your HTML might look like: + * + * @codestart html + * <div id='todos'> + * <ol> + * <li class="todo">Laundry</li> + * <li class="todo">Dishes</li> + * <li class="todo">Walk Dog</li> + * </ol> + * <a class="create">Create</a> + * </div> + * @codeend + * + * To add a mousover effect and create todos, your controller might look like: + * + * $.Controller('Todos',{ + * ".todo mouseover" : function( el, ev ) { + * el.css("backgroundColor","red") + * }, + * ".todo mouseout" : function( el, ev ) { + * el.css("backgroundColor","") + * }, + * ".create click" : function() { + * this.find("ol").append("<li class='todo'>New Todo</li>"); + * } + * }) + * + * Now that you've created the controller class, you've must attach the event handlers on the '#todos' div by + * creating [jQuery.Controller.prototype.setup|a new controller instance]. There are 2 ways of doing this. + * + * @codestart + * //1. Create a new controller directly: + * new Todos($('#todos')); + * //2. Use jQuery function + * $('#todos').todos(); + * @codeend + * + * ## Controller Initialization + * + * It can be extremely useful to add an init method with + * setup functionality for your widget. + * + * In the following example, I create a controller that when created, will put a message as the content of the element: + * + * $.Controller("SpecialController", + * { + * init: function( el, message ) { + * this.element.html(message) + * } + * }) + * $(".special").special("Hello World") + * + * ## Removing Controllers + * + * Controller removal is built into jQuery. So to remove a controller, you just have to remove its element: + * + * @codestart + * $(".special_controller").remove() + * $("#containsControllers").html("") + * @codeend + * + * It's important to note that if you use raw DOM methods (innerHTML, removeChild), the controllers won't be destroyed. + * + * If you just want to remove controller functionality, call destroy on the controller instance: + * + * @codestart + * $(".special_controller").controller().destroy() + * @codeend + * + * ## Accessing Controllers + * + * Often you need to get a reference to a controller, there are a few ways of doing that. For the + * following example, we assume there are 2 elements with className="special". + * + * @codestart + * //creates 2 foo controllers + * $(".special").foo() + * + * //creates 2 bar controllers + * $(".special").bar() + * + * //gets all controllers on all elements: + * $(".special").controllers() //-> [foo, bar, foo, bar] + * + * //gets only foo controllers + * $(".special").controllers(FooController) //-> [foo, foo] + * + * //gets all bar controllers + * $(".special").controllers(BarController) //-> [bar, bar] + * + * //gets first controller + * $(".special").controller() //-> foo + * + * //gets foo controller via data + * $(".special").data("controllers")["FooController"] //-> foo + * @codeend + * + * ## Calling methods on Controllers + * + * Once you have a reference to an element, you can call methods on it. However, Controller has + * a few shortcuts: + * + * @codestart + * //creates foo controller + * $(".special").foo({name: "value"}) + * + * //calls FooController.prototype.update + * $(".special").foo({name: "value2"}) + * + * //calls FooController.prototype.bar + * $(".special").foo("bar","something I want to pass") + * @codeend + * + * These methods let you call one controller from another controller. + * + */ + $.Class("jQuery.Controller", + /** + * @Static + */ + { + /** + * Does 2 things: + * + * - Creates a jQuery helper for this controller. + * - Calculates and caches which functions listen for events. + * + * ### jQuery Helper Naming Examples + * + * + * "TaskController" -> $().task_controller() + * "Controllers.Task" -> $().controllers_task() + * + */ + setup: function() { + // Allow contollers to inherit "defaults" from superclasses as it done in $.Class + $.Class.setup.apply(this, arguments); + + // if you didn't provide a name, or are controller, don't do anything + if (!this.shortName || this.fullName == "jQuery.Controller" ) { + return; + } + // cache the underscored names + var controller = this, + /** + * @attribute pluginName + * Setting the pluginName property allows you + * to change the jQuery plugin helper name from its + * default value. + * + * $.Controller("Mxui.Layout.Fill",{ + * pluginName: "fillWith" + * },{}); + * + * $("#foo").fillWith(); + */ + pluginname = this.pluginName || this._fullName, + funcName; + + // create jQuery plugin + this.plugin(pluginname); + + // make sure listensTo is an array + //@steal-remove-start + if (!isArray(this.listensTo) ) { + throw "listensTo is not an array in " + this.fullName; + } + //@steal-remove-end + // calculate and cache actions + this.actions = {}; + + for ( funcName in this[STR_PROTOTYPE] ) { + if (funcName == 'constructor' || !isFunction(this[STR_PROTOTYPE][funcName]) ) { + continue; + } + if ( this._isAction(funcName) ) { + this.actions[funcName] = this._action(funcName); + } + } + }, + /** + * @hide + * @param {String} methodName a prototype function + * @return {Boolean} truthy if an action or not + */ + _isAction: function( methodName ) { + if ( actionMatcher.test(methodName) ) { + return true; + } else { + return $.inArray(methodName, this.listensTo) > -1 || $.event.special[methodName] || processors[methodName]; + } + + }, + plugin : function(){}, + /** + * @hide + * This takes a method name and the options passed to a controller + * and tries to return the data necessary to pass to a processor + * (something that binds things). + * + * For performance reasons, this called twice.

Use $.Class to bridge the gap between + * jQuery's functional programming style and Object Oriented Programming. It + * is based off John Resig's [http://ejohn.org/blog/simple-javascript-inheritance/|Simple Class] + * Inheritance library. Besides prototypal inheritance, it includes a few important features: + * + * - Static inheritance + * - Introspection + * - Namespaces + * - Setup and initialization methods + * - Easy callback function creation + * + * + * The [mvc.class Get Started with jQueryMX] has a good walkthrough of $.Class. + * + * ## Static v. Prototype + * + * Before learning about Class, it's important to + * understand the difference between + * a class's __static__ and __prototype__ properties. + * + * //STATIC + * MyClass.staticProperty //shared property + * + * //PROTOTYPE + * myclass = new MyClass() + * myclass.prototypeMethod() //instance method + * + * A static (or class) property is on the Class constructor + * function itself + * and can be thought of being shared by all instances of the + * Class. Prototype propertes are available only on instances of the Class. + * + * ## A Basic Class + * + * The following creates a Monster class with a + * name (for introspection), static, and prototype members. + * Every time a monster instance is created, the static + * count is incremented. + * + * @codestart + * $.Class('Monster', + * /* @static *| + * { + * count: 0 + * }, + * /* @prototype *| + * { + * init: function( name ) { + * + * // saves name on the monster instance + * this.name = name; + * + * // sets the health + * this.health = 10; + * + * // increments count + * this.constructor.count++; + * }, + * eat: function( smallChildren ){ + * this.health += smallChildren; + * }, + * fight: function() { + * this.health -= 2; + * } + * }); + * + * hydra = new Monster('hydra'); + * + * dragon = new Monster('dragon'); + * + * hydra.name // -> hydra + * Monster.count // -> 2 + * Monster.shortName // -> 'Monster' + * + * hydra.eat(2); // health = 12 + * + * dragon.fight(); // health = 8 + * + * @codeend + * + * + * Notice that the prototype init function is called when a new instance of Monster is created. + * + * + * ## Inheritance + * + * When a class is extended, all static and prototype properties are available on the new class. + * If you overwrite a function, you can call the base class's function by calling + * this._super. Lets create a SeaMonster class. SeaMonsters are less + * efficient at eating small children, but more powerful fighters. + * + * + * Monster("SeaMonster",{ + * eat: function( smallChildren ) { + * this._super(smallChildren / 2); + * }, + * fight: function() { + * this.health -= 1; + * } + * }); + * + * lockNess = new SeaMonster('Lock Ness'); + * lockNess.eat(4); //health = 12 + * lockNess.fight(); //health = 11 + * + * ### Static property inheritance + * + * You can also inherit static properties in the same way: + * + * $.Class("First", + * { + * staticMethod: function() { return 1;} + * },{}) + * + * First("Second",{ + * staticMethod: function() { return this._super()+1;} + * },{}) + * + * Second.staticMethod() // -> 2 + * + * ## Namespaces + * + * Namespaces are a good idea! We encourage you to namespace all of your code. + * It makes it possible to drop your code into another app without problems. + * Making a namespaced class is easy: + * + * + * $.Class("MyNamespace.MyClass",{},{}); + * + * new MyNamespace.MyClass() + * + * + *

Introspection

+ *

NAME{optional:String} + *

If provided, this sets the shortName and fullName of the + * class and adds it and any necessary namespaces to the + * window object.

+ *

STATIC{optional:Object} + *

If provided, this creates static properties and methods + * on the class.

+ *

PROTOTYPE{Object} + *

Creates prototype methods on the class.
