in reply to retrieving value from ajax call to cgi page

"It is not printing". Mmm-hmm, okay, very well.
As in, you get an empty response? Or an error message of some kind?

Did you verify that your JavaScript actually works? I don't know much about (what looks like jQuery) that, but you should use a tool like Firebug or your browser's console to check that the correct request is being sent.

    yeah, i have checked through the firebug and found that the values are passing and also i created a test page and check whether the ajax call is alerting the content of the page and found that, it is working.I think, the problem is with the method, that i use to take the value.

      Okay, let's assume that your javascript does indeed work, and that the problem lies with your script.
      In that case, we will need a more complete example of your code. Is the $cgi object in the current scope? Did you turn on strict and warnings?

      For now, try the following sample: 

      #!/usr/bin/perl

use strict;
use warnings;

use CGI::Carp qw(fatalsToBrowser); # not needed per se, but very usefu
+l for debugging
use CGI;

my $cgi = new CGI();

print $cgi->header("text/javascript");
print "alert('", $cgi->param("value1") || "nothing", "');\n";
