use of document.getelementbyid in content page

P: 1

I have one master page which is having one content page.
on the content page there are some controls such as button etc.

In javascript, I want to access that button using its id as
document.getelementbyId('<%=Button7,clientID').cli ck();

I know this will not work in master content page because the control id gets changed automatically by .net..

Now my ques is how to find out the actual id of my button.

It can be <%=Ctl00_MainContent_Button7.clientId%>

I am not able to find out the changed id of the control.
and the above id does not work...

Plz guide what to do??

Thanks in Advance
