Show Javascript functions in real-time

Is there any tool or addon which can be used for testing or identifying Javascript functions in real time (i.e. on click or some events )..

e.g. on a website, I want to know after clicking on a link, which all JS functions are being called/executed..I know sometimes it is stragight开发者_JAVA百科forward from the code, but in case it uses JS libraries like jQuery, the actual function call is made from otside..

How can I do that?

*I'll really appreciate if, alongwith the addon, you just write a short description as to where can I find the Javascript finction tracking in that **

Thank you.

Try Firebug. It's one of the most useful firefox addons. Grab it here: http://getfirebug.com/

Dragonfly (Opera), or Firebug extension for Firefox, or any other good javascript debugger

See Visual Event. It is a bookmarklet that overlays element event handler information.

FireQuery is available as a firefox plugin which adds handler information inside of firebug.

Firebug includes a JavaScript profiler. Give it a try.

In Chrome, right click the page and choose Inspect element, go to the console, start javascripting! Choose the scripts tag to get debugger functionality.
