Javascript variables

I know I did this before, but I can't find the code I wrote. I need to get the value of a javascript variable into a vortex variable. Here is some sample code:

<a name="moon">
<verb noesc>
<SCRIPT LANGUAGE="JavaScript">
</verb>
function getValues() {
mediaForm.hiddenContent.value=opener.document.contentForm.content.value;
moo=opener.document.contentForm.content.value;
}
<verb noesc>
</SCRIPT>
</verb>
<BODY onLoad="getValues()">
<FORM METHOD="POST" NAME="mediaForm" ACTION="/cgi-bin/texis/cls/course">
<INPUT TYPE="HIDDEN" NAME="hiddenContent">
$moo
</BODY>
</A>

Thanks!!!!

Brian

Assuming your javascript sets hiddenContent to the desired value you can access it in vortex as $hiddenContent .

You wuld think that was true, but the hidden field only allows acces of the variable on the next html page, not this one.

Correct, Vortex runs on the server to generate the page that is sent to the browser. Once the HTML reaches the browser the browser runs the Javascript and Vortex is no longer involved.

If you need the value in a Vortex variable then it will need to be passed in the HTTP request somehow. If you are trying to display it as in your example you could use javascript again to display it on the client.
