Default How Do I Pass 2 Variables in Javascript

Hi there

Could anyone help me with the following problem:

I've got a dropdown box which is populated from a database. The dropdown displays a TName but passes through TID.

<select name="TID" id="TID" onchange='javascript:window.location="pageurl_edit .asp?TID=" + this.value;'>

This all worked fine on my insert page but I need to tweak it for my edit page and am not really a javascript bod!

I need to pass through another variable called UID

On my edit page i've got some asp:
<%
Dim uid
if Request("uid") <> "" then uid = Request("uid")
%>

So, what I need to put in my select box onchange function is this:
pass through TID which is equal to the value of the select box (as before) and pass through UID which is equal to Request("uid") but I don't know how to write this in javascript.

Can anyone help?

Thanks in advance

Lucy

I think is what you want... UID is going to be the same for all TIDs right?

<select name="TID" id="TID" onchange="window.location='pageurl_edit.asp?TID=' + this.value + '&uid=<%=uid%>';">

The slight problem with that solution is that it uses an IE only construct, a select element does not have a value in standard HTML. The general construct would be:
Code:
<select name="TID" id="TID" onchange="window.location='pageurl_edit.asp?TID=' + this.options[this.selectedIndex].value + '&uid=<%=uid%>';">
