How do I find out what javascript function is being called by an object's onclick event?

Question

How do I find out what javascript function is being called by an object's onclick event? Even better, can I then find out which included .js file that function is in?

Answer 1

I use Chrome's Developer Tools for this:

Check the click box, and then click on the element on the page you want to find the handler for. If you are using jQuery (or similar library), you may have to step through their code before you get to yours.
