JS Is there a way to check if an event exists?

Question

I am trying to detect if a certain webkit event 'webkitAnimationEnd' is supported by the browser, to do so I like to check if the event exists. But I can't seem to figure out how. Does anyone have a clue?

Answer 1

Detecting event support without browser sniffing suggests that this ought to work:

'onWebkitAnimationEnd' in document.createElement('div');
