Attaching a javascript function to a page in order to make it execute right before the doPostBack is invoked

Question

How to intercept any postback in a page? - ASP.NET

I need to achieve the following target: I have an Asp.Net web form and I have a javascript function function myfunc(). I know that everytime that a control causes the page to post back, it automatically makes a call to the generated doPostBack() javascript function.

What I need to do is finding a way to tell the page to make a call to myfunc() right before EVERY call to doPostBack is performed.

In few words: before the doPostBack script activates, the page must run another javascript function!

Thankyou

Have you tried to call your function in the onsubmit event on the body tag? — Hector Sanchez, Jun 29 '11 at 22:11

I assume you tried using the ScriptManager Class?

RegisterScript would be a good start...
