. each (callback)	Iteration matching elements, executing callback for each element
. length	Gets the number of matching elements
. Get ()	Gets a list of DOM nodes corresponding to the matching elements
. Get (Index)	Gets the DOM node in the matching element that corresponds to the specified index
. ToArray ()	Gets a list of DOM nodes corresponding to the matching elements

7. Event Binding

Between

Method	Description
. Ready (handler)	Dom and CSS after full load handler
. On (type,[selector],[data],ha Ndler)	to bind the type event and specify the event handler handler, and if the selector is specified, execute the event delegate
. On (Events,[selector],[data])	bind multiple event handlers based on events of event objects
. Off (type,[selector],handler)	dismiss an event handler on an element bound
. bind (Type,[data],handler)	binding type events and specifying event handlers handler
. One (Type,[data) , handler)	binds the type event and specifies that the event handler Handler,handler be unbound immediately after being invoked
. Unbind ([Type],[handler])	unbind the specified event handler from bind to the element (not specified to remove all specified)
. Delegate (Selector,type,[data],handler)	binds the type event to the element that matches selector and specifies the event handler handler
. Delegate (selector,handlers)	binds the type event to the element that matches selector and specifies the event handler handlers
. Undelegate (Selector,type,[handler])	to remove delegate specified event handler for element binding

Method	Description
. Trigger (Type,[data])	Triggers an event on an element and performs the default action for the event
