Solution:
A cpan module CGI::Ajax is available to make the use of Ajax in your web application. It is an object-oriented module that provides a unique mechanism for using perl code asynchronously from javascript- enhanced HTML pages.
A very simple example of CGI::Ajax :-
#!/usr/bin/perl -w
use strict;
use CGI;
use CGI;
use CGI::Ajax;
my $cgi = new CGI;
my $pjx = new CGI::Ajax('checkname' => \&checkname);
print $pjx->build_html( $cgi, \&ajax_html);
sub checkname{
my $input = shift;
my $output = $cgi->param('name');
return $output;
}
sub header {
my $header = qq~<HTML>
<HEAD>
</HEAD>
<BODY>~;
return $header;
}
sub ajax_html{
my $html_header = header();
my $html_footer = footer();
my $html_body = qq~<input type="button" value="Click Me" onclick="checkname(['name__lalit'], ['lalitdiv']);">
<div id="lalitdiv">Ajaxx</div>~;
my $full_html = $html_header.$html_body.$html_footer;
return $full_html;
}
sub footer{
my $footer = qq~</BODY>
</HTML>~;
return $footer;
}
