can-control-plugin is deprecated

Registers a jQuery plugin function for Controls.

Overview

The can.Control.plugin extension is a plugin for creating and accessing controls with jQuery helper methods. It uses the control's can.Construct.fullName fullName or a static [can.Control.plugin.static.pluginName pluginName] attribute for the name of the control.

For example, the following plugin:

var Tabs = can.Control({
  pluginName : 'tabs'
},{
  init : function(element, options, arg1){ },
  update : function(options) {}
})

Can now be created directly on the jQuery collection like:

$(".tabs").tabs();

Note: This plugin only supports jQuery.

Invoking Methods

You can invoke methods on a control instance after its created through a few different approaches.

Once a controller is initialized on a DOM element, you can invoke a method by calling the plugin with the method name followed by the parameters for that method. When calling a method and it returns a value other than undefined, this value will be returned. Otherwise the method call will return the jQuery object (for chaining).

var MyTodo = can.Control({
  pluginName : 'my_todo'
}, {
  addTask: function(name, task){
    this.element.append(name + ": " + task)
  },

  getTasks : function() {
    return this.element.text();
  }
});

// Initialize MyTodo
$('.my_todo').my_todo();

// Calls addTask, returns the jQuery element
$('.my_todo').my_todo("addTask", 'Brian', 'Sweep garage') // -> jQuery
// Calls getTasks, returns the element text
$('.my_todo').my_todo("getTasks") // -> Brian: Sweep garage

You can also retrieve the control instance and invoke the method directly.

var control = $('.my_todo').control();
control.addTask('Brian', 'Sweep garage');

For more information on this, see [jQuery.fn.control] or [jQuery.fn.controls].

Demo

See: src/index.html

The demo shows creating a plugin widget and then updating the widget's times variable for each time the button was clicked.

API

Static

{String} pluginName

Allows you to define the name of the jQuery plugin.

var Filler = can.Control({
	pluginName: 'fillWith'
},{});

$("#foo").fillWith();

Setting the static pluginName property allows you to override the default name with your own.

If you don't provide a pluginName, the control falls back to the fullName attribute:

can.Control('Ui.Layout.FillWith', {}, {});
$("#foo").ui_layout_fill_with();

Prototype

jQuery.fn.controls([type])

• Param: {String|can.Control} control - The type of Controls to find
• Return {can.Control} - The controls associated with the given elements.

When the widget is initialized, the plugin control creates an array of control instance(s) with the DOM element it was initialized on using can.data method.

The controls method allows you to get the control instance(s) for any element either by their type or pluginName.

var MyBox = can.Control({
   pluginName : 'myBox'
}, {});

var MyClock = can.Control({
   pluginName : 'myClock'
}, {});

//- Inits the widgets
$('.widgets:eq(0)').myBox();
$('.widgets:eq(1)').myClock();
 
$('.widgets').controls() //-> [ MyBox, MyClock ]
$('.widgets').controls('myBox') // -> [MyBox]
$('.widgets').controls(MyClock) // -> MyClock

jQuery.fn.control([type])

• Param: {String|can.Control} control - The type of Control to find
• Return {can.Control} - The first control found

This is the same as $().controls except that it only returns the first Control found.

//- Init MyBox widget
$('.widgets').my_box();

<div class="widgets my_box" />

$('.widgets').controls() //-> MyBox

update(newOptions)

• Param: {Object} newOptions - Options to merge into the current options.

Update extends options with the options argument and rebinds all events. It re-configures the control.

For example, the following control wraps a recipe form. When the form is submitted, it creates the recipe on the server. When the recipe is created, it resets the form with a new instance.

 var Creator = can.Control({
	 "{recipe} created" : function(){
	 	this.update({recipe : new Recipe()});
	 	this.element[0].reset();
	 	this.element.find("[type=submit]").val("Create Recipe")
	 },
	 "submit" : function(el, ev){
	 	ev.preventDefault();
	 	var recipe = this.options.recipe;
	 	recipe.attrs( this.element.formParams() );
	 	this.element.find("[type=submit]").val("Saving...")
	 	recipe.save();
	 }
});
 
$('#createRecipes').creator({ recipe : new Recipe() })

Update is called if a control's plugin helper is called with the plugin options on an element that already has a control instance of the same type. If you want to implement your own update method make sure to call the old one by calling can.Control.prototype.update.apply(this, arguments);. For example, you can change the content of the control element every time the options change:

 var Plugin = can.Control({
 	pluginName: 'myPlugin'
 }, {
 	init : function(el, options) {
 	this.updateCount = 0;
 	this.update({
 		text : 'Initialized'
 	});
 },
 update : function(options) {
 	// Call the can.Control update first.
 	// Use this._super when using can/construct/super
 	can.Control.prototype.update.call(this, options);
 	this.element.html(this.options.text + ' ' +
 		(++this.updateCount) + ' times');
 	}
 });
 
 $('#control').myPlugin();
 $('#control').html();
 // Initialized. Updated 1 times
 
 $('#control').myPlugin({ text : 'Calling update. Updated' });
 $('#control').html();
 // Calling update. Updated 2 times
