This is the line of code in the ASP page.

 
Response.Write("   <tr><a href='Panel.asp?STRING;'><center>"&vbcrlf)

PassStr is the string variable I wish to insert in place of STRING.

PassStr is a javascript variable generated by the client page.

I can't seem to get the syntax right, can anyone help me out?

If it's a javascript variable generated on the SAME page, you can't do it, it's impossible.

Because javascript doesn't execute until the page gets to the client's browser (it's clientside code). At that point the server-side code (ASP) has already finished executing.

Maybe there's a way that you can duplicate how the javascript generates that string, and generate it server-side in the ASP part as well?

The resultant line of code on the generated page would be:

<tr><a href='Panel.asp?STRING;'><center>

I need the syntax to use a variable (PassStr) after the ? ,perhaps I should ask this question in HTML?

I just need to insert a reference to the variable in the href before I send the page. I will not be referencing the var server side it will be referenced from html clientside The page Init() function will create the variable.

K then instead of ASP, use JS to print it:

<script type="text/javascript">
document.write('<tr><a href="Panel.asp?'+PassStr+'"><center>');
</script>

Sorry, your not getting it, it is tough to explain this is a line of code I have tried that does not work, it is the server side code.

Response.Write("<tr><a href='Panel.asp?"&javascript:Qstring()&"'><center> "&vbcrlf)

my hope was that the link would call a script to return the variable value. Sorry this is so tough to explain, you have been very helpful in past.

I want the client side code to be something like:

<tr><a href='Panel.asp?(PassStr)'><center>

If PassStr="abc=xyz&rst=uvw" I want the line to evaluate to:

<tr><a href="Panel.asp?abc=xyz&rst=uvw"><center>

And I'm saying, you can't access a javascript variable from server-side code, because the javascript environment DOES NOT EXIST until AFTER the server-side code has finished executing.

If the variable you're talking about (PassStr) is generated by javascript (clientside), you can't access it serverside. If it's generated by JSCRIPT (not javascript) on server-side (by using RUNAT=SERVER), then you'd access it just like you would a vbscript variable:

Response.Write("<tr><a href='Panel.asp?"&PassStr&"'><center> "&vbcrlf)

But if I understand you correctly, the variable PassStr is created by clientside javascript, then you can't response.write it because the variable doesn't exist until after the page leaves the server.

You can, however, add a link to the document from the javascript environment, AFTER the page has loaded. You do not need server-side code for this, you need the javascript code I gave you. Or if you don't want to write it out directly with document.write(), you can modify the contents of an existing div by using document.getElementById('thedivsidgoeshere').inner HTML='whatever html you want to put into the div goes here'.

Basically the order of execution goes:

1. Client requests document from server
2. Server reads document, and parses/runs any server-side code (ASP code occurs)
3. Server now has HTML document generated by server-side code, no more ASP can be executed
4. Server sends HTML documents (which contains javascript) to Client
5. CLIENT (not server) reads document, and parses/runs and client-side code (javascript occurs here).
6. Client displays final document, javascript continues to run after page is displayed.

If the variable PassStr is truly a javascript variable as you said, that variable does not exist until step 5. At that point the page has already been sent to the visitors browser when the javascript starts running. The visitors computer does not have the ability to do a response.write (ASP code) because it is not a web server.

All ASP code (include the response.write you are wanting to create) is executed during step 2. At that point, the javascript environment does not exist. No javascript variables are accessible (although server-side JSCRIPT variables are). There is no way to access the javascript variable "PassStr" because that variable does not exist yet.

ASP and Javascript do not execute simultaneously. Server-side code occurs first, then client-side code occurs. Once client-side code starts running, it is ON THE CLIENT, so all server-side code has already been processed. The client's browser wouldn't know what to do with a Response.Write statement.

I don't want to access the variable server side I just want to put the variable name in the href string so that it can be resolved client side. I want the syntax for using a variable in the href string. I want the page that is sent to contain the variable "name" not the value. when the page is executed at client side it will resolve the variable when the link is clicked. the variable will be given a value onload by clientside script. notice that half the string "panel.asp?" is a literal in string I need to concantate the variable name to this string so that client side it will be recognised as a variable and not a literal.

Use the javascript code I gave you to write out the <a> tag including the variable.

I'm not sure I get what you are trying to achieve but as a educated guess it sounds like you want to send a placeholder to the client, then have the client replace the placeholder with the actual values.

so based on that premise

<%
with response
    .write "<tr><a href="
    .write chr(34)
    .write "Panel.asp?"
    .write "[PLACEHOLDER]"
    .write chr(34)
    .write "><center>"
    .write vbcrlf
end with
%>

Then you can write some client side code to extract the <a>nchor elements from the document and replace the [PLACEHOLDER] with whatever value is needed.

Not exactly what I wanted but it will do, Thx Chris, you too nyef! **** and here I was thinking that a variable was a placeholder!

Sorry I couldn't help you more; I'm still not sure why you're intent on doing it that way.

It seems silly (IMO) to have the server write out something that isn't complete, then have the client code (javascript) complete it. Why not just have the server leave it blank, and have the client generate the whole thing including the link?

A variable is a very specific type of placeholder, and not the type you want or need. A variable is a slot in a computer's memory that can hold values, letting them be manipulated and swapped out as you need. That's kind of what you want to do, only instead of in RAM, you want to create the placeholder on your server, and have it manipulated and swapped out on the client. The way programming variables work, as in process memory working areas, the boundaries between two machines makes it impossible to "share" them.
