I have a couple of forms that are misbehaving in FireFox, but work fine in IE.
when i do submit( with submit button) a javascript function validates all of the fields entered, and stops the submission if there is an error.
Sample (obviously not working code):
[HTML] <html>
<head>
<script type="text/javascript">
function Submit()
{
// do something, like form field validation before submitting
return true;
} else {
return false; // do nothing, do not submit the form
}
}
</script>
</head>
<body>
<form name="myForm" action="form.cg i" onSubmit="retur n Submit()>
Some form fields here<br/>
<input type="submit" value="Submit" >
</form>
</body>
</html>
[/HTML]
THE PROBLEM:
In IE, the script performs as expected.
In FireFox (tested in v2.0.0.3):
* if the form validates correctly, it gets submitted twice:
* if the form doesn't validate then nothing happen.
Am I coding something wrong here? Why is FireFox submitting the form two times..

What's the character encoding in your browser?
The browser encoding is - UTF-8
I've narrowed it down to my javascript stmt. -
function mysubmit(){
-
alert('1');
-
document.forms[0].submit();
-
alert('2');
-
}
-
alert('1') is displayed - No request yet submitted, Press OK, alert 2 is displayed. 2 requests submitted.

Change the action of your form:
[HTML]
<form ... action="mySubmi t();">
[/HTML]
And then instead of returning true in mySubmit: -
document.forms[0].action = 'thepage.php';
-
document.forms[0].submit();
-
I tried to make the form action="" and set the action explicitly in the js, returned true from it. Still doesn't work.
My requirement is that the js should be called onchange of a text field, hence I've made the form action as an empty string

If the form's action is an empty string, then it will use the current page as the action. Instead, do this: -
form.action = 'void('');';

That doesn't help either

What's not working about it?
I'm not sure I understand how the code is fitting together; perhaps if you posted the current implementation.

Solved the problem, just wanted to update the post with what he problem was-
One of my open-source js files was putting <img src="".... which was causing the page url to be accessed again.
Changed it access a null image, and it worked.
Please note that all other changes - Setting of response headers, changing the focrm action etc. were reverted back, and it still worked.
Thanx for all your help

Glad you got it working. It can be so frustrating when you realise you'd been barking up the wrong tree.

to load in the "parent" window/page. I have this working in IE but
cannot get it to work in Firefox. The parent window correctly loads

I've got a form inside a PHP script that posts to itself, does some
processing on the PHP side, and if it looks good, PHP sends a HEADER
command that redirects the user out. All was fine until I added a
button disabler onSubmit to keep users from submitting twice. Now the
form disables the button as requested but just refreshes the page... it
doesn't get to the HEADER command.
Any idea what the problem might be?

The doPostBack javascript functioning is not submitting the page when called by linkbuttons (or an

On the web server side ( on ButtonClick_Event) the user's input(name,date,cc

My problem is, users may think that the button click did not work, so they
