ajax - How to remove the handler in javascript -

I am adding some documents, where this script will execute on AJAX calls each time.

But how can I remove the handler on the outcome of AJAX, where I tried to use Undanderer but its effect was affected for the first time.

Is there any way to check that this event is alive?

If you want to remove an event handler with javascript, you have to cancel it like this:

< / Div>

  document.getElementById ("yourelement"). Remove Event Alisoner ("Your Event", Your Function);
