         url: "http://www.google.com",   
         async: false,

<body>
<input type="button" value="submit" />

You can use the object data recieved after success of the ajax to retrive the url in response — Learner

The var response doesn't exist out the ajax call, you need to use it insice de success call event. — frikinside

This is because of the Same Origin Policy

From the JQuery ajax method documentation:

Due to browser security restrictions, most "Ajax" requests are subject to the same origin policy; the request can not successfully retrieve data from a different domain, subdomain, port, or protocol.

It has to be a path relative to the page on which the JavaScript code is running.

I have one website url which contains json response so that how can I get that json response.

Is that URL on the same domain as the JavaScript?

You can also add error callback and debug it what happening.

$.ajax({ type: "GET",   
     url: "http://www.google.com",   
     async: false,
     success : function(data, textStatus)
     {
         alert(data);
         alert(textStatus);
     },
     error : function(XMLHttpRequest, textStatus, errorThrown)
     {
         alert(XMLHttpRequest);
         alert(textStatus);
         alert(errorThrown);
     }

});
