ASP.NET

I have a custom web part placed on one of the application page in SharePoint. This page it seems already have a function which gets executed on windows beforeunload javascript event.

My problem is that i too need to execute some client side code (to prompt user for any unsaved changes in my web part) on windows beforeunload event.

How can i achieve this ? I mean let the default event be fired as well as call my function also ?

Appreciate any help.

Nikhil.
