Is it possible to remove one specific event handler from an event with multiple handlers?

Question

As i searched for the solution of a problem i have right now, i found this thread: jQuery: more than one handler for same event. Now i wonder if it is possible to remove just a single one of these handlers?

Answer 1

It is possible, if you don't use anonymous callbacks:

var $elt = $(...);  function clickHandler1(event){...} function clickHandler2(event){...}  // bind both $elt.click(clickHandler1); $elt.click(clickHandler2);  // unbind just the first $elt.unbind('click', clickHandler1); 

A wild Demo appeared!

See also: .unbind() docs.

Answer 2

Actually, you can do it using anonymous callbacks via event namespacing:

$elt.bind('click.handler1', function(event) {     alert('click handler 1'); });  $elt.unbind('click.handler1'); 

See modified demo here.

And here for more information.

This was added in jQuery 1.4.3, which actually came out more than 4 months before the question was asked.
