Struts and Java Script problem using Styleid

I have this problem in my Struts application. It will working correctly on the IE. Now i move on to the Forefox. In that i have following issue. For example declare the button like.

<html:button property='open' onclick='doOpen();'>

I disabled this button using getElementById(it work on the IE). But Firefox doesnot disabled the button without styleid. How can i resole this issue. i Couldn't able to add the styleid to thousand of jsp pages. Is there any common solution to fix this problem.

Hi. You can get this object to use getElementByNameTag and I really don't believe that this code works in IE correctly and doesn't work in FF. It is impossible. Sorry I just hate IE )).

is there any chance to solve this problem through html tag library and struts jar modification.
