Is it possible to find JavaScript events that are tied to a specific piece of HTML?

Question

I'm working with someone else's code, and I want to be able to see what JavaScript they have tied to a particular button on the page. Is there some way to watch what code is being fired off by clicking the button in FireBug or something?

Answer 1

Give Visual Event a try. It's a bookmarklet that will highlight all Elements in a page with events bound to them and will give you a nice little readout on what's bound to each Element.
