4.18 How do I get a perl/asp/php variable into client-side js?

You have the serverside language generate the javascript:

jsvar="<%= aspvar %>";
jsvar="<?php echo $phpvar ?>";

etc. For communication between client and server, after a page has
loaded, there are a number of "Remote Scripting" options available:

Variables should be declared always, therefore it should be

var jsvar="<%= aspvar %>";
var jsvar="<?php echo $phpvar; ?>";

Then you use the means of the available programming language/environment.

Perl:

print "var jsvar='$perlvar';\n";

# Here-document syntax
print <<EOT
var jsvar="$perlvar";
EOT

POSIX 1003.2 compatible:

echo "var jsvar='$shellvar';";
printf "var jsvar='$shellvar';\n";

It really is pretty basic stuff in any programming language. Hopefully you
got the idea now.

Please ask language-related questions in the appropriate newsgroup, and use
a quote character prefix, preferably "| ", when you quote from third-hand
sources such as the FAQ.
