(Whiteboard: [nsbeta2+][WORKSFORME, waiting for input])
I have a shopping cart page that uses JavaScript and cookies extensively. In
the HTML of the page I have a 'hidden' input tag that I set to a null string
initially. When the user clicks on one of two submit links, I use JavaScript to
call a function. In this function I have some logic to determine what goes into
this 'hidden' tag and gets passed along to my CGI script. Then I call the
form.submit() function to call the script. Somehow the changes I make to the
'hidden' tag are not getting set, it only passes along the null string. This
works perfectly in Netscape 4.x and IE4/5.

I tried this with following testcase and it works fine for me.
<html> <head>
<title></title>
<script language="javascript">
<!--
function testit(text)
{
if (document.workform.hid.value=='old value'){
document.workform.hid.value='new value'}
else if (document.workform.hid.value=='new value'){
document.workform.hid.value='old value'}
else{
document.workform.hid.value='another value'}
alert("Hidden Value= " + document.workform.hid.value);
}
// -->
</script>
</head><body>
<FORM NAME="workform">
<INPUT TYPE="hidden" NAME="hid" VALUE="old value">
<INPUT TYPE="button" NAME="but" VALUE="Change Hidden Value"
onClick="testit(this.form.hid.value);">
</FORM>
</body> </html>
For me its working fine.

Nominating nsbeta2. We have to start drawing a line on DOM0 backward
compatibility; these bugs are supposed to be a high priority for nsbeta2 per the
beta2 criteria.

Erick Jensen, could you please supply some more info here, is the code you use
different in some way from the code desale tested with?
I'm currently unable to use the site because of the javascript: url problems in
mozilla, but the sample that desale showd above works just fine for me too.

I've discovered that the problem isn't actually with changing hidden input
tags, it's with transmitting form data via the HTTP header to a CGI script. It
doesn't seem to be sending it accross. I wrote a simple HTML form with a
CGI/Perl script that displays the fields entered. They show up blank in N6,
but show up fine in N4 and IE5. This may actually be a bug that has already
been reported, I didn't check. In any case it's pretty severe. Try this link
to see what I mean: http://www.llmedico.com/ejensen/test.html. I am also
sending you (jst@netscape.com) the two source files.

jst, this sounds like form submission to me. I'll take a look at this one. :)
(Feel free to take it back if you have or are working on a solutions!)

Interestingly, if I make the action of the form http://pollmann.net/echo.cgi it
seems to have no problems with the post - wonder if this is a server side issue?

Ah, good old bug 27006. The post data is getting sent correctly the first time,
the server is responding with a document with a <META> tag that contains a
charset. This causes the form to be posted again, this time (due to the bug)
without the post data!
