Method Summary

_methodTemplate() protected

Helper function to wrap repetitive simple method templating.
domReady() public

Create a domReady event. For jQuery. This method does not bind a 'traditional event' as $(document).bind('ready', fn) Works in an entirely different fashion than $(document).ready() The first will not run the function when eval()'d as part of a response The second will. Because of the way that ajax pagination is done $().ready() is used.
drag() public

Create a Draggable element
drop() public

Create a Droppable element
each() public

Create an iteration over the current selection result.
effect() public

Trigger an Effect.
event() public

Add an event to the script cache. Operates on the currently selected elements.
get() public

Create javascript selector for a CSS rule
request() public

Create an $.ajax() call.
serializeForm() public

Serialize a form attached to $selector. If the current selection is not an input or form, errors will be created in the Javascript.
slider() public

requestAction() public ¶

requestAction( mixed $url , array $extra = array() )

Calls a controller's method from any location. Can be used to connect controllers together or tie plugins into a main application. requestAction can be used to return rendered views or fetch the return value from controller actions.

Under the hood this method uses Router::reverse() to convert the $url parameter into a string URL. You should use URL formats that are compatible with Router::reverse()

Passing POST and GET data

POST and GET data can be simulated in requestAction. Use $extra['url'] for GET data. The $extra['data'] parameter allows POST data simulation.

Parameters

mixed $url: String or array-based url. Unlike other url arrays in CakePHP, this url will not automatically handle passed and named arguments in the $url parameter.
array $extra optional array(): if array includes the key "return" it sets the AutoRender to true. Can also be used to submit GET/POST data, and named/passed arguments.

Returns

mixed

Boolean true or false on success/failure, or contents of rendered action if 'return' is set in $extra.

toString() public ¶

toString( )
