One of two ways: either put the Javascript function right in your php output so that as it outputs the javacript it contains the values, OR split up the query string with your javascript to get at the values. Of the two, I'd say the first is probably more graceful. A perl-y example:


#!/usr/bin/perl 
 $myvalue = 'From the script'; 
 $content = qq¦ 
 <html><head> 
 <script type="text/javascript"> 
  alert('$myvalue'); 
 </script> 
 </head><body>test</body></html> 
 ¦; 
print "content-type: text/html\n\n"; 
print $content;
