Question

I want to use jquery to implement ajax response from perl script on the server.But when I use such code, I got nothing. I can get the result from the url in a browser, so I don’t know where is wrong.

$(document).ready(function(){
$("button").click(function(){

$.ajax({
  'type': 'GET',
  'url': 'http://XXXX/cgi-bin/XXX.pl?title=dd',
  'async': true,
  'success': function(data) {
        alert(data);
  }
});

});
});

Answer 1

If url field contain http://server.domain/ and if you try to access a server from a webpage located elswhere than http://server.domain/ (like in your desktop for sample, accessed via file:///), probably you need to add a field Access-control-allow-origin: * in the header sent by your perl CGI:

#!/usr/bin/perl -w

use CGI;
my $q=new CGI;

print $q->header(-type=>"text/plain", -Access_Control_Allow_Origin=>"*")."Answer";
