[jQuery] How do I do a Ajax request before form submits

[HairyJim]

Hi,

I created a form which I wanted to submit using jQuery (I'm new to jq)
but before the submit I wanted to run an ajax request and attach the
returned result to the form for posting. However it seems the form
submits before the ajax request is returned, I can see the code
generated in the DB but it never gets attached to the form.

If I set the return false; and hit submit the ajax process runs and is
attached to the forms hidden field correctly but obviously the form
does not get submitted, any thoughts for a 'green skin' on this
matter?

<script type="text/javascript">
$(document).ready(function()
{
        $("form#RegForm").submit(function()
        {
                $.get("servertime.php",function(response)
                {
                        response=response.split("\n");
                        $("#serialnumber").val(response[0]);
                        $("#passcode").val(response[1]);
                });
        return true;
        });
});
</script>

Cheers
Jim
