Callbacks.add (callbacks)

Description: add a callback or a collection of callbacks to the callback list.

Added version: 1.7callbacks.add (callbacks)

Callbacks

Type: Function, Array

A function, or an array of functions, is used to add to the callback list.

This method returns the callback object (this) that binds it.

Example

Use callbacks.add () to add a new callback to the callback list:

/ / a sample logging function to be added to a callbacks list

Var foo = function (value) {

Console.log ("foo:" + value)

}

/ / another function to also be added to the list

Var bar = function (value) {

Console.log ("bar:" + value)

}

Var callbacks = $.Callrooms ()

/ / add the function "foo" to the list

Callbacks.add (foo)

/ / fire the items on the list

Callbacks.fire ("hello")

/ / outputs: "foo: hello"

/ / add the function "bar" to the list

Callbacks.add (bar)

/ / fire the items on the list again

Callbacks.fire ("world")

/ / outputs:

/ / "foo: world"

/ / "bar: world"
