I need to check if some events are already bound on an element.

For example 

$(".animate").click(function(){
    alert('Here comes action');
});

and

$(".someOtherSelector").click(function(){
    alert('some other action');
});

HTML

<a class="animate"></a>
<a class="someOtherSelector animate"></a>

In second function I need to check if there is an event already bound on this element. If so it should not execute alert('some other action');.

I'm using jQuery version 1.10.1.

  • Actually i saw this question already. But in 1.10.1 $(".someOtherSelector").data('events') returns null. And if i using $(this) it returns null too – Leo Ray Oct 04 '13 at 12:44

As of jQuery 1.8, the event data is no longer available for data. Read this jQuery blog post. You should now use this:

jQuery._data(element, "events")

Code

$('.someOtherSelector').each(function(){
    console.log($._data(this, "events"));
});

you can get the events $(".someOtherSelector").data('events'), then check if the required event is present or not.

​var events = $._data( $(".someOtherSelector")[0], "events" );
if(events.indexOf("click") == -1) {
  $(".someOtherSelector").click(function(){
    alert('some other action');
  });
}
