Thanks for looking into my code. But I didn't get you properly. So rephrasing my question below.

my $pjx = new CGI::Ajax( 'exported_func' => \&perl_func );
print $pjx->build_html( $cgi, \&Show_HTML); # First ajax call
my $sec_pjx = new CGI::Ajax( 'exported_func' => \&sec_perl_func );
print $sec_pjx->build_html( $cgi, \&Show_HTML);  # Second ajax call

Both this ajax calls produce different output on page. How do I combine them in single perl code file.

Ok, one $pjx per page/htmldocument, with all the functions that page uses, however many that is

 my $pjx = CGI::Ajax->new(
  first => \&foo,
  second => \&bar, ## keep adding functions here
                   ## unique names of course
);

Hi, Thanks your information was useful. Code is working perfect now.

my $cgi = new CGI;                # cgi 
                                # ajax function
my $pjx = new CGI::Ajax( 'exported_func' => \&perl_func, 'exported_fun
+c_two' => \&perl_func_two);
print $pjx->build_html( $cgi, \&Show_HTML);

Note: I am new to perlmonks, how do I mark this question as answer, or solved one.
