No, this doesn't do anything. I have to be doing something wrong
because even if I set all the return statements to false, the page still
gets submitted. Here's what I have:
var btnPress = false;
function verify () {
if (btnPress) {
return false; }
else { btnPress = true;
return false; }
return false; }
<FORM action="disableSubmitFinal.asp?i=<%=sTitle%>&n=<%=sName%>"
method=POST id=frmEmail name=frmEmail onSubmit="JavaScript:verify();">
I put some alert statements in the function so I know it does get run,
and the btnPress variable changes appropriately. But return false
doesn't seem to stop the form from submitting.

OK I will put my JS head on properly.
If a form has an onSubmit() property that calls a script, then if that
script returns true the submit will take place, but if false, it won't
be submitted.
So this code should stop the form being submitted more than once:
<script>
var btnPress = false;
function verify ( ) {
if (btnPress) return false;
else {
btnPress = true;
return true;
}
}
</script>
<form onSubmit="JavaScript:verify( );"...
Obviously I can't test easily, as on my local system the submit is
instant and your situation is the original form remains on screen for
some time.
Next question what is the form's 'action='? If not specified, the page
will just refresh, the inputs will all empty and the button will work
as well as before. Well I had to ask.
