On the difference between band (). Live (). Delegate (). On () in jquery.

Bind (TYPE,[DATA],FN) binds event handlers for specific events of each matching element

$ ("a"). Bind ("click", Function () {alert ("OK");});

Live (TYPE,[DATA],FN) attaches an event handler function to all matching elements, even if the element is added later in the

$ ("a"). Live ("Click", Function () {alert ("OK");});

delegate (SELECTOR,[TYPE],[DATA],FN) the specified element (which belongs to the child element of the selected element) adds one or more event handlers and specifies the function to run when these events occur

$ ("#container"). Delegate ("A", "click", Function () {alert ("OK");})

On (EVENTS,[SELECTOR],[DATA],FN) an event handler that is bound to one or more events on the selection element

Difference:

@1. Bind () is directly bound on the element

@2. Live () is bound to an element by a bubbling way. More appropriate for the list type, bound to the document DOM node. and. Bind () have the advantage of supporting dynamic data.

@3. Delegate () is a more accurate, small-scale use of event proxies with better performance. Live ()

@4. On () is the latest 1.9 version of the new event binding mechanism that incorporates the previous three ways
