how to call aspx variable from Javascript

J

Jade

I saw some web page saying I could do it this way in
javascript:
var iNumber = <%#publicvarname [or] publicpropertyname %>

but it doesn't seem to work. I have this piece of code
here in javascript:
<script language="javascript">
var sessionServer = "<%#jsTestServer%>";
alert(sessionServer);
</script>

and the variable is defined in the C# code behind:
public string jsTestServer
= "\\\\TestServer\\TestSession\\";

when I run it, alert has no message in it.

Jade,

Assuming that variable is in scope, you would use the following:

<% = jsTestServer %>

Actually, what you should do is use RegisterClientScriptBlock to generate
your client-side script on the server and then register it on the client.

the thing is I need to do it on the client side. I've
tried <% = jsTestServer %> before. It didn't work. It
didn't even pop up the alert this time. Or maybe I did
something wrong. Could you please give me a more
complete piece of code?

Thanks!

Jade,

A complete source sample is not going to help you because the problem is
almost certainly that jsTestServer is out of scope. That's why using this
type of legacy architecture is not recommended in ASP.NET. Instead, you
need to use RegisterClientScriptBlock to create the client-side code on the
server and then write it to the page.

javascript is client side and your variable is server side......
