thanks budd

well i tried to disabled the submit button through onclick but i prevents my form from submition instead i worked this way and have made it

<SCRIPT LANGUAGE="JavaScript">
var submitcount=0;

function checkFields()
{
if (submitcount == 0)
{
submitcount++;
return true;
}
else
{
alert("This form has already been submitted. Thanks!");
return false;
}
}
</script>

and...

<html:form action="/someAction" onsubmit="return checkFields()">

Changing the attribute value to:

  this.disabled = 'false';

would still disable the control.

Don't. If the submission fails and the user needs to resubmit, the button may still be disabled when they use the Back button to return (this behaviour varies between browsers, but does occur).

If multiple submissions breaks your server-side code, then that code is broken itself. Detect and deal with it properly on the server.

Or you could use DD's scripts: http://www.dynamicdrive.com/dynamici...sableenter.htm
