Default set a asp variable with a value in Javascript

How can i set a asp variable with a value in Javascript?

JS Code:

<script language="JavaScript" type="text/javascript">
<!--

if (acrobat.ver5)
{
    // if Acrobat 5.0 or newer is installed, do Acrobat 5.0 stuff.
    document.write("Acrobat V5 + is installed")
    var installed_pdf = "<%inst_pdf=yes%>"
}
else if (acrobat.installed)
{
    // do older Acrobat stuff
    document.write(acrobat.version);
}
else
{
    // Acrobat is NOT installed. Do something else.
    document.write("Acrobat is NOT installed.")
}

//-->
</script>

ASP Code:

<% response.write "Installed PDF = " & inst_pdf & "<br>" %>

This doesnt seem to work.

you need to think about where this stuff is running, and the sequence of events.
1st. asp runs on webserver and sends html (including js) to browser
2nd. browser reads html and runs js

so now can you see why it doesn't work?

Hii Crimpiccoo
JavaScript is case sensitive so true is not the True :)
<%
str1="X"
str2="X"


%>
<script>
x=<%= str1=str2%>
//x=True
y=<%= str1="x"%>
//y=False
x1= <%=LCase(str1=str2) %>
//x1=true OK :)
y1=<%= LCase(str1="x")%>
//y1=false OK :)
</script>

now check the values of x and y it's contain "True" and "False"
where as in javascript true and false
var installed_pdf =<%= LCase(inst_pdf="no")%>;

Hope this will help you :)

Cheers :)

vinod
