Keep "Submit Button" Disbaled by default.

Then on each mandatory field put

onBlur="function();"

in this function write the code to check all the mandatory fileds are filled, if yes then enable your submit button or no keep disabled.

Call the same "function();" on each filed blur.

I hope this is clear.

Cheers...

You could try to write a function that will check each field for correctness and then use the form id to submit it with javascript. Instead of having a submit input use a button instead that onclick calls the function.

<script type="text/javascript">
function checkThenSubmitForm()
{
<!-- form checking instructions -->;
document.getElementById('theForm').submit();
return true;
}
</script>
<form id="theForm" action="whatever.php" method="post">
<!-- THE INPUT FIELDS -->
<input type="button" value="Submit" onclick="checkThenSubmitForm()">

I think thats right, but the idea is there.
