can I tell whether a form is being submitted

Hi all!

I have a form called "theForm". How can I tell if the user has submitted the form or hit the submit button??

Is it..

if(document.theForm.onsubmit()){

do something

}else{

}

<form action="xxxx.yyy" method="post" onsubmit="alert('call any function here'); return true;">

If you want to validate the form, at the same time, do something like

<form action="xxxx.yyy" method="post" onsubmit="return validateForm(this);">

and have validateForm return true if no errors or false for one or more errors.

You may do it dynamically, as well:

onload=function(){
var form=document.forms['theForm'];
form.onsubmit=function(){
// do something
}
}
