passing javascript variable into asp variable using vbscript

The subject pretty much sums up what I need to do. Here is what I
have so far, but still can't figure out how to get it working:

<script language="javascript" type="text/javascript">
function fillForm()
{
// split the query string into pieces
var qs = location.search.substr(location.search.indexOf("?" )+1);
qs = qs.split("&");
alert(qs); // qs is the variable that I need to pass into a
// vbscript var. This actually works up to here.
'<%the_name%>' = qs // this line does not work, but is what I need
// to do.
}
</script>
later in the code:
<%
Response.write ("<script>fillForm();</script>")
Response.write("This is the variable: " & the_name)
%>

On the page it obviously comes up as "This is the variable: " and that
is it...blank for the_name.

I need to use javascript to get the variables out of the url, such as:
http://www.x.com/test.asp?Dell%20Computer%20Corp
qs will then end up being "Dell Computer Corp" and I need to make a
vbscript variable to also be that so I can query/load/etc certain
stuff in asp to display on the site.

Thanks for your help!

I don't think it is possible, because the vbscript (the server code) will
always be executed before the page ever reaches the browser where the
javascript is executed. Please correct me if I am wrong. I wish someone
would post a website or write a book on the subject of communication between
server-side and client-side scripts.

But surely if you are using ASP you can do the following:

URL : http://www.testsite.com/test.asp?Com...omputer%20Corp

<% varCompany = Request.QueryString("Company") %>
to extract from the URL to variable varCompany

and where you need to place the variable:

<%= varCompany %>

all in ASP
The only bit using VB of Javascript is the creation of the URL (which here I
am creating from items in a form, in the case of someone NOT using the
submit button!) And then reloading the page.

NewURL = "location.asp?";
var EleNum = 0;
var EleNumMx = document.plform.elements.length;
do {
if (document.plform[EleNum].type == "select-one") {
if (document.plform[EleNum].selectedIndex != 0) {
NewURL += document.plform[EleNum].name + "=" +
document.plform[EleNum].value + "&";
}
}
if(document.plform[EleNum].type == "text") {
if (document.plform[EleNum].value != 0 ) {
NewURL += document.plform[EleNum].name + "=" +
document.plform[EleNum].value + "&";
}
}
if(document.plform[EleNum].type == "textarea") {
if (document.plform[EleNum].value != 0 ) {
NewURL += document.plform[EleNum].name + "=" +
document.plform[EleNum].value + "&";
}
}
} while(++EleNum < EleNumMx);
window.location=NewURL;

Hope this helps

I had actually figured out using what you Richard and John mentioned
yesterday late afternoon. You know how it is when you work on
something for hours and hours and then all of a sudden you just get it
to work! :) What you guys said makes sense though and my problem was
that I didn't know you could do all of that just in vbscript. It even
ends up being cleaner also. All I ended up doing, just like you guys
said is:

<a href=""tier2.asp?prod=" & i & """>" & i & "</a>
where i is a vbscript variable from a database

and then in the next page:
the_name = request.querystring("prod")

prod has %20 for spaces and the_name just has spaces. It is exactly
what I was looking for.

Thanks guys for you input.

To get the whole query string:

<%
the_name = Request.QueryString()
%>

You can pass it to client but not the other way around:

<script language="javascript">
var the_name = ""
</script>
<%
Dim the_name
the_name = Request.QueryString()
Response.write("the name is " & the_name)
Response.write("<script>the_name=""" & the_name & """;</script>")
%>
<script language="javascript">
alert(the_name)
</script>

I just noticed that if "&" is passed, after you do a querysting, it
drops everything passed the "&" even though vbscript variables can
hold & inside.

For instance, if the URL is www.x.asp/?prod="dell%20&%20ibm"
then if you do this on the next page:
the_name = request.querystring("prod")
it will only come up as "dell" instead of "dell & ibm"

Everything else seems to work fine, but this. Anyone have a
suggestion in how to avoid this?

Thanks

Mike, thanks so much...that is even better now cause now all I needed to do is:

the_name = Replace(the_name, "%20", " ")

and I get exactly what I want!

Thanks for all of your inputs...have a good July 4th.

Alternatively use the javascript escape function to encode your "&" into a
%Code. Then unescape it before using it.
