hi,
i have a jsp/html page, in that i have two buttons. lets say b1 and b2,both buttons are doing diff functions.
onclick of b1 i'm calling a javascript-function where i wanna "diable b2(button2)" - IN NETSCAPE ,im getting that in IE,but i want that in netscape.

you could do the following:
var flag=true;
function onClickButton1()
{
. . .
t=false;
. . .
}
function onClickButton2()
{
if (flag)
{
. . .
