in reply to How do I send information to Javascript from perl?

You probably just need to interpolate the Perl values into the JavaScript code as it's sent.

For example, if "foo" is a value you want the JS code to see, your program should at some point do something like this in the midst of transmitting JS code:

print "foo = '\Q$foo\E'\n";

NOTE: Using \Q should protect against most metacharacters in the variable, but you should be quite careful to determine if it does what's appropriate for JS quoting conventions.

    one approach would be to redirect to an html file with a query string after you've done all your processing in your perl such as: 
    $username = 'username';

print "Location: html.html?username=$username\n\n";

    from there, you can simply grab the variable on the html using this: 
    <script language="JavaScript"><!--
if (location.search.length > 0)
    eval('var ' + location.search.substring(1));
//--></script>
