Javascript - Onsubmit problem in Firefox

[bubs81]

Hi,

Here's the first line of my HTML form...

<form target="_self" onsubmit="return preProcessForm();" action="somewhere" method="post">

preProcessForm looks like...

function preProcessForm()
{
var url = "pre_process_form.php";
 
run_AJAX_Request(url);
 
return true;
}

I am trying to get pre_process_form.php to run in the background (using AJAX), prior to submitting the form. It works fine every time in IE 7/8, and it works 80% of the time in Firefox 3.0.11.

The problem occurs when the user submits the form. They are navigated to the appropriate destination, however, 20% of the time, the AJAX function appears to have not been called or the php script doesn't seem to have been called. I suspect this might be a FF bug but I'm trying to achieve some sort of short term work-around. The idea is - submit the form when pre_process_form.php has finished. Can anyone suggest something?

I have moved your post to the correct forum, Javascript / AJAX. Please try to post in the correct forum using the links from the Topic menu as you will get a more rapid response if you do.

What does pre_process_form do? If you're going to submit anyway (as in, a refresh/reload/unload of the page will take place), why not run this code in the action page?
