They are a great technique + * when you want to develop JavaScript + * independently of the backend. + * + * ## Types of Fixtures + * + * There are two common ways of using fixtures. The first is to + * map Ajax requests to another file. The following + * intercepts requests to /tasks.json and directs them + * to fixtures/tasks.json: + * + * $.fixture("/tasks.json","fixtures/tasks.json"); + * + * The other common option is to generate the Ajax response with + * a function. The following intercepts updating tasks at + * /tasks/ID.json and responds with updated data: + * + * $.fixture("PUT /tasks/{id}.json", function(original, settings, headers){ + * return { updatedAt : new Date().getTime() } + * }) + * + * We categorize fixtures into the following types: + * + * - __Static__ - the response is in a file. + * - __Dynamic__ - the response is generated by a function. + * + * There are different ways to lookup static and dynamic fixtures. + * + * ## Static Fixtures + * + * Static fixtures use an alternate url as the response of the Ajax request. + * + * // looks in fixtures/tasks1.json relative to page + * $.fixture("tasks/1", "fixtures/task1.json"); + * + * $.fixture("tasks/1", "//fixtures/task1.json"); + * + * ## Dynamic Fixtures + * + * Dynamic Fixtures are functions that get the details of + * the Ajax request and return the result of the mocked service + * request from your server. + * + * For example, the following returns a successful response + * with JSON data from the server: + * + * $.fixture("/foobar.json", function(orig, settings, headers){ + * return [200, "success", {json: {foo: "bar" } }, {} ] + * }) + * + * The fixture function has the following signature: + * + * function( originalOptions, options, headers ) { + * return [ status, statusText, responses, responseHeaders ] + * } + * + * where the fixture function is called with: + * + * - originalOptions - are the options provided to the ajax method, unmodified, + * and thus, without defaults from ajaxSettings + * - options - are the request options + * - headers - a map of key/value request headers + * + * and the fixture function returns an array as arguments for ajaxTransport's completeCallback with: + * + * - status - is the HTTP status code of the response. + * - statusText - the status text of the response + * - responses - a map of dataType/value that contains the responses for each data format supported + * - headers - response headers + * + * However, $.fixture handles the + * common case where you want a successful response with JSON data. The + * previous can be written like: + * + * $.fixture("/foobar.json", function(orig, settings, headers){ + * return {foo: "bar" }; + * }) + * + * If you want to return an array of data, wrap your array in another array: + * + * $.fixture("/tasks.json", function(orig, settings, headers){ + * return [ [ "first","second","third"] ]; + * }) + * + * $.fixture works closesly with jQuery's + * ajaxTransport system. Understanding it is the key to creating advanced + * fixtures. + * + * ### Templated Urls + * + * Often, you want a dynamic fixture to handle urls + * for multiple resources (for example a REST url scheme). $.fixture's + * templated urls allow you to match urls with a wildcard. + * + * The following example simulates services that get and update 100 todos. + * + * // create todos + * var todos = {}; + * for(var i = 0; i < 100; i++) { + * todos[i] = { + * id: i, + * name: "Todo "+i + * } + * } + * $.fixture("GET /todos/{id}", function(orig){ + * // return the JSON data + * // notice that id is pulled from the url and added to data + * return todos[orig.data.id] + * }) + * $.fixture("PUT /todos/{id}", function(orig){ + * // update the todo's data + * $.extend( todos[orig.data.id], orig.data ); + * + * // return data + * return {}; + * }) + * + * Notice that data found in templated urls (ex: {id}) is added to the original + * data object. + * + * ## Simulating Errors + * + * The following simulates an unauthorized request + * to /foo. + * + * $.fixture("/foo", function(){ + * return [401,"{type: 'unauthorized'}"] + * }); + * + * This could be received by the following Ajax request: + * + * $.ajax({ + * url: '/foo', + * error : function(jqXhr, status, statusText){ + * // status === 'error' + * // statusText === "{type: 'unauthorized'}" + * } + * }) + * + * ## Turning off Fixtures + * + * You can remove a fixture by passing null for the fixture option: + * + * // add a fixture + * $.fixture("GET todos.json","//fixtures/todos.json"); + * + * // remove the fixture + * $.fixture("GET todos.json", null) + * + * You can also set [jQuery.fixture.on $.fixture.on] to false: + * + * $.fixture.on = false; + * + * ## Make + * + * [jQuery.fixture.make $.fixture.make] makes a CRUD service layer that handles sorting, grouping, + * filtering and more. + * + * ## Testing Performance + * + * Dynamic fixtures are awesome for performance testing. Want to see what + * 10000 files does to your app's performance? Make a fixture that returns 10000 items. + * + * What to see what the app feels like when a request takes 5 seconds to return? Set + * [jQuery.fixture.delay] to 5000. + * + * @demo jquery/dom/fixture/fixture.html + * + * @param {Object|String} settings Configures the AJAX requests the fixture should + * intercept. If an __object__ is passed, the object's properties and values + * are matched against the settings passed to $.ajax. + * + * If a __string__ is passed, it can be used to match the url and type.

Understanding + * $.Observe is essential for using $.route correctly. + * + * You can + * listen to changes in an Observe with bind and + * delegate and change $.route's properties with + * attr and attrs. + * + * ### Listening to changes in an Observable + * + * Listen to changes in history + * by [jQuery.Observe.prototype.bind bind]ing to + * changes in $.route like: + * + * $.route.bind('change', function(ev, attr, how, newVal, oldVal) { + * + * }) + * + * - attr - the name of the changed attribute + * - how - the type of Observe change event (add, set or remove) + * - newVal/oldVal - the new and old values of the attribute + * + * You can also listen to specific changes + * with [jQuery.Observe.prototype.delegate delegate]: + * + * $.route.delegate('id','change', function(){ ... }) + * + * Observe lets you listen to the following events: + * + * - change - any change to the object + * - add - a property is added + * - set - a property value is added or changed + * - remove - a property is removed + * + * Listening for add is useful for widget setup + * behavior, remove is useful for teardown. + * + * ### Updating an observable + * + * Create changes in the route data like: + * + * $.route.attr('type','images'); + * + * Or change multiple properties at once with + * [jQuery.Observe.prototype.attrs attrs]: + * + * $.route.attr({type: 'pages', id: 5}, true) + * + * When you make changes to $.route, they will automatically + * change the hash. + * + * ## Creating a Route + * + * Use $.route(url, defaults) to create a + * route. A route is a mapping from a url to + * an object (that is the $.route's state). + * + * If no routes are added, or no route is matched, + * $.route's data is updated with the [jQuery.String.deparam deparamed] + * hash. + * + * location.hash = "#!type=videos"; + * // $.route -> {type : "videos"} + * + * Once routes are added and the hash changes, + * $.route looks for matching routes and uses them + * to update $.route's data. + * + * $.route( "content/:type" ); + * location.hash = "#!content/images"; + * // $.route -> {type : "images"} + * + * Default values can also be added: + * + * $.route("content/:type",{type: "videos" }); + * location.hash = "#!content/" + * // $.route -> {type : "videos"} + * + * ## Delay setting $.route + * + * By default, $.route sets its initial data + * on document ready. Sometimes, you want to wait to set + * this data. To wait, call: + * + * $.route.ready(false); + * + * and when ready, call: + * + * $.route.ready(true); + * + * ## Changing the route. + * + * Typically, you never want to set location.hash + * directly. Instead, you can change properties on $.route + * like: + * + * $.route.attr('type', 'videos') + * + * This will automatically look up the appropriate + * route and update the hash. + * + * Often, you want to create links. $.route provides + * the [jQuery.route.link] and [jQuery.route.url] helpers to make this + * easy: + * + * $.route.link("Videos", {type: 'videos'}) + * + * @param {String} url the fragment identifier to match. + * @param {Object} [defaults] an object of default values + * @return {jQuery.route} + */ + $.route = function( url, defaults ) { + // Extract the variable names and replace with regEx that will match an atual URL with values. + var names = [], + test = url.replace(matcher, function( whole, name ) { + names.push(name) + // TODO: I think this should have a + + return "([^\\/\\&]*)" // The '\\' is for string-escaping giving single '\' for regEx escaping + }); + + // Add route in a form that can be easily figured out + $.route.routes[url] = { + // A regular expression that will match the route when variable values + // are present; i.e. for :page/:type the regEx is /([\w\.]*)/([\w\.]*)/ which + // will match for any value of :page and :type (word chars or period). + test: new RegExp("^" + test+"($|&)"), + // The original URL, same as the index for this entry in routes. + route: url, + // An array of all the variable names in this route + names: names, + // Default values provided for the variables. + defaults: defaults || {}, + // The number of parts in the URL separated by '/'. + length: url.split('/').length + } + return $.route; + }; + + extend($.route, { + /** + * Parameterizes the raw JS object representation provided in data. + * If a route matching the provided data is found that URL is built + * from the data.

When template engines [jQuery.View.register register] + * themselves, you are able to: + * + * - Use views with jQuery extensions [jQuery.fn.after after], [jQuery.fn.append append], + * [jQuery.fn.before before], [jQuery.fn.html html], [jQuery.fn.prepend prepend], + * [jQuery.fn.replaceWith replaceWith], [jQuery.fn.text text]. + * - Template loading from html elements and external files. + * - Synchronous and asynchronous template loading. + * - [view.deferreds Deferred Rendering]. + * - Template caching. + * - Bundling of processed templates in production builds. + * - Hookup jquery plugins directly in the template. + * + * The [mvc.view Get Started with jQueryMX] has a good walkthrough of $.View. + * + * ## Use + * + * + * When using views, you're almost always wanting to insert the results + * of a rendered template into the page. jQuery.View overwrites the + * jQuery modifiers so using a view is as easy as: + * + * $("#foo").html('mytemplate.ejs',{message: 'hello world'}) + * + * This code: + * + * - Loads the template a 'mytemplate.ejs'. It might look like: + *

<h2><%= message %></h2>

+ * + * - Renders it with {message: 'hello world'}, resulting in: + *

<div id='foo'>"<h2>hello world</h2></div>

+ * + * - Inserts the result into the foo element. Foo might look like: + *

<div id='foo'><h2>hello world</h2></div>

+ * + * ## jQuery Modifiers + * + * You can use a template with the following jQuery modifiers: + * + * + * + * + * + * + * + * + * + *

[jQuery.fn.after after]	$('#bar').after('temp.jaml',{});
[jQuery.fn.append append]	$('#bar').append('temp.jaml',{});
[jQuery.fn.before before]	$('#bar').before('temp.jaml',{});
[jQuery.fn.html html]	$('#bar').html('temp.jaml',{});
[jQuery.fn.prepend prepend]	$('#bar').prepend('temp.jaml',{});
[jQuery.fn.replaceWith replaceWith]	$('#bar').replaceWith('temp.jaml',{});
[jQuery.fn.text text]	$('#bar').text('temp.jaml',{});

+ * + * You always have to pass a string and an object (or function) for the jQuery modifier + * to user a template. + * + * ## Template Locations + * + * View can load from script tags or from files. + * + * ## From Script Tags + * + * To load from a script tag, create a script tag with your template and an id like: + * + *

<script type='text/ejs' id='recipes'>
+	 * <% for(var i=0; i < recipes.length; i++){ %>
+	 *   <li><%=recipes[i].name %></li>
+	 * <%} %>
+	 * </script>

+ * + * Render with this template like: + * + * @codestart + * $("#foo").html('recipes',recipeData) + * @codeend + * + * Notice we passed the id of the element we want to render. + * + * ## From File + * + * You can pass the path of a template file location like: + * + * $("#foo").html('templates/recipes.ejs',recipeData) + * + * However, you typically want to make the template work from whatever page they + * are called from. To do this, use // to look up templates from JMVC root: + * + * $("#foo").html('//app/views/recipes.ejs',recipeData) + * + * Finally, the [jQuery.Controller.prototype.view controller/view] plugin can make looking + * up a thread (and adding helpers) even easier: + * + * $("#foo").html( this.view('recipes', recipeData) ) + * + * ## Packaging Templates + * + * If you're making heavy use of templates, you want to organize + * them in files so they can be reused between pages and applications. + * + * But, this organization would come at a high price + * if the browser has to + * retrieve each template individually. The additional + * HTTP requests would slow down your app. + * + * Fortunately, [steal.static.views steal.views] can build templates + * into your production files. You just have to point to the view file like: + * + * steal.views('path/to/the/view.ejs'); + * + * ## Asynchronous + * + * By default, retrieving requests is done synchronously. This is + * fine because StealJS packages view templates with your JS download. + * + * However, some people might not be using StealJS or want to delay loading + * templates until necessary. If you have the need, you can + * provide a callback paramter like: + * + * $("#foo").html('recipes',recipeData, function(result){ + * this.fadeIn() + * }); + * + * The callback function will be called with the result of the + * rendered template and 'this' will be set to the original jQuery object. + * + * ## Deferreds (3.0.6) + * + * If you pass deferreds to $.View or any of the jQuery + * modifiers, the view will wait until all deferreds resolve before + * rendering the view. This makes it a one-liner to make a request and + * use the result to render a template. + * + * The following makes a request for todos in parallel with the + * todos.ejs template. Once todos and template have been loaded, it with + * render the view with the todos. + * + * $('#todos').html("todos.ejs",Todo.findAll()); + * + * ## Just Render Templates + * + * Sometimes, you just want to get the result of a rendered + * template without inserting it, you can do this with $.View: + * + * var out = $.View('path/to/template.jaml',{}); + * + * ## Preloading Templates + * + * You can preload templates asynchronously like: + * + * $.get('path/to/template.jaml',{},function(){},'view'); + * + * ## Supported Template Engines + * + * JavaScriptMVC comes with the following template languages: + * + * - EmbeddedJS + *

<h2><%= message %></h2>

+ * + * - JAML + *

h2(data.message);

+ * + * - Micro + *

<h2>{%= message %}</h2>

+ * + * - jQuery.Tmpl + *

<h2>${message}</h2>

+ + * + * The popular Mustache + * template engine is supported in a 2nd party plugin. + * + * ## Using other Template Engines + * + * It's easy to integrate your favorite template into $.View and Steal.
