@page jquerymx jQueryMX @parent index 0 @description jQuery Model View Controller and extensions.

jQueryMX is a collection of useful jQuery libraries that provide the missing functionality necessary to implement and organize large-scale jQuery applications.

Every part of jQueryMX can be used stand-alone which keeps your app super light. $.Model, $.View, and $.Controller are only 7kb minified and gzipped. This includs their $.String, $.Class, and destroyed-event dependencies.

If you are using [steal], simply steal the plugin you need like:

steal('jquery/controller', function(){

Or, use the [ download builder] to select the files you need.

jQueryMX is divided into four core areas:

  • DOM Helpers
  • Language Helpers
  • Special events
  • Model, View, Controller and Class ( Read [mvc the walkthrough] )

The following highlights jQueryMX's functionality.

DOM Helpers

[dom DOM helpers] extend jQuery with extra functionality for manipulating the DOM. For example, [dimensions] lets you set the outer width and height of elements like:


THe following are the other dom plugins:

  • [jQuery.cookie Cookie] - Set and get cookie values.
  • [jQuery.fixture Fixture] - Simulate Ajax responses.
  • [jQuery.fn.closest Closest] - Use the open child selector in event delegation.
  • [ Compare] - Compare the location of two elements rapidly.
  • [jQuery.fn.curStyles CurStyles] - Get multiple css properties quickly.
  • [jQuery.fn.formParams FormParams] - Serializes a form into a JSON-like object.
  • [jQuery.fn.selection Selection] - Gets or sets the current text selection.
  • [jQuery.fn.within Within] - Returns elements that have a point within their boundaries.
  • [jQuery.Range Range] - Text range utilities.
  • [jQuery.route] - Routes for history-enabled ajax apps.

Special Events

jQueryMX comes packed with jQuery [specialevents special events] and event helpers.

  • [jQuery.Drag Drag] - Delegatable drag events.
  • [jQuery.Drop Drop] - Delegatable drop events.
  • [jQuery.Hover Hover] - Delegatable hover events.
  • [jQuery.event.special.destroyed Destroyed] - Know when an element is removed from the page.
  • [jQuery.event.special.resize Resize] - Listen to resize events on any element.
  • [jQuery.event.swipe Swipe] - Delegatable swipe events.
  • [jQuery.Event.prototype.key Key] - Get the character from a key event.
  • [jQuery.event.special.default Default] - Provide default behaviors for events.
  • [jquery.event.pause Pause-Resume] - Pause and resume event propagation.

Language Helpers

Language helpers make it easy to perform various functions on JavaScript data.

  • [jQuery.Object Object] - compare objects and sets
  • [jQuery.Observe Observe] - Listen to changes in JS Objects and Arrays
  • [jQuery.String String] - String helpers
  • [jQuery.toJSON toJSON] - create and convert JSON strings
  • [jQuery.Vector Vector] - vector math


[jQuery.Class $.Class] provides simple prototypal inheritance. It's used by [jQuery.Controller $.Controller] and [jQuery.Model $.Model].

// create a Monster Class
// static methods 

  // a list of all monsters
  monsters : []
// prototype methods

  // called when a new monster is created
  init : function(name){

    // stores a reference to the name = name;

    // adds this monster to the collection of monsters

  // a method on monsters
  speak : function(){
    alert( + " says hello.");

// create a monster
var hydra = new Monster("hydra");   

// call a method on a monster


[jQuery.Model $.Model] encapsulates the service and data layer. The following connects to a JSON REST service and adds a helper to let us know if we can destroy a task:

  findAll : "GET /tasks.json",
  findOne : "GET /tasks/{id}.json",
  create  : "POST /tasks.json",
  update  : "PUT /tasks/{id}.json",
  destroy : "DELETE /tasks/{id}.json"
  canDestroy : function(){
    return this.acl.indexOf('w') > -1

Assuming '/tasks.json' returns a JSON array like ...

  "id"       : 1,
  "name"     : "take out trash",
  "acl"      : "rw",
  "createdAt": 1303000731164 // April 16 2011
  "id"       : 2,
  "name"     : "do the dishes",
  "acl"      : "r" ,
  "createdAt": 1303087131164 // April 17 2011

... the following will retrieve all tasks from the server and then destroy tasks that the user is able to destroy:

Task.findAll({}, function(tasks){
  for(var i =0; i < tasks.length; i++){

    var task = tasks[i];

    if( task.canDestroy() ){

Model has a number of other useful features such as:

  • Listening to [ events].

    @codestart // listen to name changes on a task task.bind("name", function(ev, newName){ alert('task name = '+newName); }); //change the task's name task.attr('name', "laundry"); //listen for Tasks being created: Task.bind("created", function(ev, newTask){ // create newTask's html and add it to the page }); @codeend
  • [jquery.model.typeconversion Converting] raw data into more useful objects.

    @codestart $.Model('Task', { convert : { 'date' : function(raw){ return new Date(raw) } }, attributes : { 'createdAt' : 'date' } },{}); var task = new Task({ createdAt : 1303087131164}); // createdAt is now a date. task.createdAt.getFullYear() // -> 2011 @codeend
  • Methods and utilities on [jQuery.Model.List lists] of instances.

    @codestart // define a task list $.Model.List('Task.List',{ // add a helper method to a collection of tasks canDestroyAll : function(){ return this.grep(function(task){ return task.canDestroy(); }).length === this.length } }); Task.findAll({}, function(tasks){ //tasks is a Task.List tasks.canDestroyAll() //-> boolean }) @codeend
  • [ Deferreds]

    @codestart // make 2 requests, and do something when they are // both complete $.when( Task.findAll(), People.findAll() ) .done(function(tasks, people){ // do something cool! }) @codeend


[jQuery.View $.View] is a template framework. It allows you to use different template engines in the same way.

The following requests tasks from the model, then loads a template at "task/views/tasks.ejs", renders it with tasks, and inserts the result in the #tasks element.

Task.findAll( {}, function(tasks){

  $('#tasks').html( 'task/views/tasks.ejs', tasks );

tasks.ejs might look like:

<% $.each(this, function(task){  %>
  <li><%= %></li>
<% }) %>

$.View understands [ deferreds] so the following does the exact same thing!

 $('#tasks').html( 'task/views/tasks.ejs', Task.findAll() );

Any template engine can be used with $.View. JavaScriptMVC comes with:

  • [jQuery.EJS]
  • [Jaml]
  • [Micro]
  • [jQuery.tmpl]


[jQuery.Controller $.Controller] is a jQuery widget factory. The following creates a $.fn.list [jquery.controller.plugin plugin] that writes a message into an element:

$.Controller( "List", {
  init: function( ) {
    this.element.text( this.options.message );

// create the list
$('#list').list({message: "Hello World"});

$.Controller lets you define [jQuery.Controller.static.defaults default options]:

$.Controller( "List", {
  defaults: {
    message : "I am list"
  init: function( ) {
    this.element.text( this.options.message );

// create's a list that writes "I am list"

Controller's best feature is that it organizes your event handlers, and makes [jquery.controller.listening binding and unbinding] event handlers extremely easy. The following listens for clicks on an LI elements and alerts the element's text:

$.Controller( "TaskList", {
  init: function(){
    // uses a view to render tasks
    this.element.html( "tasks.ejs", Task.findAll() );
  "li click": function(el){
    alert( el.text() );

Controller makes it easy to parameterize event binding. The following listens for tasks being created and inserts them into the list:

$.Controller( "TaskList", {
  init: function( ) {
    // uses a view to render tasks
    this.element.html("tasks.ejs", Task.findAll());
  "{Task} created": function( Task, ev, newTask ) {
    this.element.append( "tasks.ejs", [newTask] );

Finally, this makes it very easy to create widgets that work with any model:

$.Controller( "List", {
  init: function(){
    // uses a view to render tasks
    this.element.html( this.options.view, 
                       this.options.model.findAll( ));
  "{model} created": function( Model, ev, instance ){
    this.element.append( this.options.view, [instance] );

$("#tasks").list({ model: Task, view: 'tasks.ejs' });
$("#people").list({model: Person, view: 'people.ejs' });
