How to overwrite jquery event handlers

taras picture taras · Apr 12, 2009 · Viewed 57.8k times · Source

I'll try to explain the problem with a simple code.

var fireClick = function() { alert('Wuala!!!') };

$('#clickme').click(fireclick);
$('#clickme').click(fireclick);

So now it will obviously alert 2 times but i need it alert only once. Tried so many ways, but no result.

Thanks.

As of jQuery 1.7 you should be using off to remove event handlers and on to add them, though you can still use the click shorthand.

$('#clickme').off('click').on('click', fireclick);
$('#clickme').off().on('click', fireclick);

Original answer:

If you want to replace all click handlers, call unbind first without a function argument. If you want to replace all event handlers, don't specify the event type.

$('#clickme').unbind('click').click(fireclick);
$('#clickme').unbind().click(fireclick);
