jQuery.proxy()

jQuery.proxy( function, context )

Returns: Function

Description: Takes a function and returns a new one that will always have a particular context.

Arguments

jQuery.proxy( function, context )

version added: 1.4

function

The function whose context will be changed.

context

The object to which the context (`this`) of the function should be set.

jQuery.proxy( context, name )

version added: 1.4

context

The object to which the context of the function should be set.

name

The name of the function whose context will be changed (should be a property of the 'context' object.

This method is most useful for attaching event handlers to an element where the context is pointing back to a different object. Additionally, jQuery makes sure that even if you bind the function returned from jQuery.proxy() it will still unbind the correct function, if passed the original.

Example

Enforce the context of the function.

var obj = {
  name: "John",
  test: function() {
    alert( this.name );
    $("#test").unbind("click", obj.test);
  }
};

$("#test").click( jQuery.proxy( obj, "test" ) );

// This also works:
// $("#test").click( jQuery.proxy( obj.test, obj ) );
