This is probably OT, but anyway... It may be the way you are referencing the form. Try 'document.forms[0].add.disabled = ( element.checked );'
That worked for me - I didn't use struts though - I just messed around with static html: <html> <SCRIPT LANGUAGE="JavaScript"> function check(element) { //alert(element.checked); document.forms[0].add.disabled = ( element.checked ); } </script> <body> <form> <input type="checkbox" onclick="check(this)" name="myname" value="myvalue"/> <input type="submit" name="add" /> </form> </body> </html> > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Sent: 25 November 2003 16:20 > To: [EMAIL PROTECTED] > Subject: checkbox onclick event not getting called > > > Hi, > > My code is like the following, when I click the checkbox, > nothing happened (the 'add' button suppose to get disabled). > I put a alert statment in the javascript, and didn't get it > showed when click the checkbox... seems the function didn't > get called at all, can anybody tell me why?
