Class Ext.form.Action

Package:	Ext.form
Defined In:	Action.js
Class:	Action
Subclasses:	Action.Load, Action.Submit
Extends:	Object

The subclasses of this class provide actions to perform upon Forms.

Instances of this class are only created by a Form when the Form needs to perform an action such as submit or load. The Configuration options listed for this class are set through the Form's action methods: submit, load and doAction

The instance of Action which performed the action is passed to the success and failure callbacks of the Form's action methods (submit, load and doAction), and to the actioncomplete and actionfailed event handlers.
