javascripting form values

[Mike Mueller]

How can something seemingly so simple make me pull out so
much hair.....

I am using javascript to get browser info and screen
resolution. This information will be tacked into a form
using hidden fields. I am getting nothing for the values of
the hidden fields. All else is saving fine to the database.

script portions:

<form method="POST" action="--WEBBOT-SELF--" name="Info"
onSubmit="">
--snip--
<input type="hidden" name="Browser" value="">
<input type="hidden" name="FullBrower" value="">
<input type="hidden" name="Resolution" value="">
</form>
<script>
form.info.Browser.value=navigator.appName + " " +
parseInt(navigator.appVersion);
form.info.FullBrowser.value=window.navigator.userAgent;
form.info.Resolution.value=ScrnSz;
</script>

Hi Mike,

I'd grab the browser/ua information server side and just get the res client
side
<form....
<input type="hidden" name="Browser"
value="<%=request.servervariables("http_user_agent")%>">
<input type="hidden" name="Resolution" value="">
</form>
<script type="text.javascript">
document.forms[0].Resolution.value = screen.width + 'x' + screen.height;
</script>

Having said that a post came up earlier today in the client group about the
usefullness of screen resolution versus window size - if you'd rather get
window size look at the the thread next door

You must be overlooking or not displaying JavaScript errors. "form.info"
would cause one. Instead, try referring to the form as "document.forms[0]".
Example:

document.forms[0].Browser.value=navigator.appName + " " +
parseInt(navigator.appVersion);

Also, what exactly is "ScrnSz" supposed to be? You can't just make up terms
and expect them to work somehow. In the context of your code, it looks like
a variable. But it's never declared, and you never assign a value to it. Try
using screen.height and screen.width instead.

Once agaoin I need to say thank you.

Part of my problem was mizspeling. I am now functioning
with window.document.formfield.value.

I knew I could pull the referer server side, but that would
cross out of my realm into the next bank of cubicles who are
just going to import this into interdev

Screen resolution is desired for this site as due to the
nature of high quality images being displayed.

Thank you Kevin

besides what I stated to Jon, scrnsz was defined higher up
in the code based on those variables you named
