<script>
 var w = window.open('http://studiothorn.com/recive.html');
 w.postMessage('anand.', 'http://studiothorn.com');
 w.postMessage('aff.', 'http://studiothorn.com');
 function receiveMessage(event)
 {
alert("hello");
if (event.origin !== "http://studiothorn.com")
 return;
 }
 window.addEventListener("message", receiveMessage, false);
 </script>

and secondly code is about reciver

     function receiveMessage(event)
    {
     alert("aff");
     if (event.origin !== "http://studiothorn.com")
     return;
      event.source.postMessage("hi there yourself!  the secret response " +"is:
       rheeeeet!",event.origin);
      }
    window.addEventListener("message", receiveMessage, false);

    . in second code is about reciving text send by the sender.
