<html xmlns="http://www.w3.org/1999/xhtml"> <head>     <title>calling classic web services jquery</title>     <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>     <script type="text/javascript">       $(document).ready(function () {         $("a#sayhello").click(function (e) {           e.preventdefault();            $.ajax({             type: 'post',             data: '{firstname:10,lastname:15}',           //  url: 'service.asmx/sayhello',             url: 'http://192.168.1.20/myservice/service.asmx/sayhello',             contenttype: 'application/json; charset=utf-8',             datatype: 'json',              success: function(response) {                  alert(response.d); //getting response json              },             failure: function(msg) {                 alert(msg);             }           });         });       });         </script> </head> <body>   <input id="name" /><a id="sayhello" href="#">greetings!</a>   </body> </html>

can please me going wrong in code..?? if run in asp.net environment, works perfectly. if host this, doesn't work. please me...!!

are sure web service responding in json format? answers in xml. <script> block should go in <body> , not in <head>.
