Code:

$.ajax({ 
url: "http://..............", 
type:"GET", 
dataType: 'jsonp', 
crossDomain: true, 
contentType:"application/javascript", 
success: function (data) { 
    alert(data);
}, 
error: function (errorMEssage, Errtext) { 
    alert(Errtext);
} 
});

Error:

uncaught syntaxerror : unexpected token <

But that won't work. You cannot use XML for cross domain AJAX calls. — Darin Dimitrov, Oct 17 '13 at 07:28

You cannot make cross domain AJAX calls using JSONP to a server that returns XML. If you want to be able to make a cross domain AJAX call you have 2 possibilities:

use JSONP -> your server needs to support it.
use CORS -> your server AND client browser need t support it.

If your server supports CORS your request may look like this:

$.ajax({ 
    url: "http://..............", 
    type:"GET", 
    crossDomain: true, 
    success: function (data) { 
        alert(data);
    }, 
    error: function (errorMEssage, Errtext) { 
        alert(Errtext);
    } 
});

Use JSONP or CORS. You will need to modify the remote endpoint to support one of the 2. Only then you will be able to make cross domain AJAX calls. – Darin Dimitrov Oct 17 '13 at 07:29
NO. CORS means Cross Origin Resource Sharing. Please read the article I have linked to in my answer. Your server side script will need to send the `Access-Control-Allow-Origin` response headers to an OPTIONS verb request. Once you ensure that the remote server sends this header you could remove the `dataType: 'jsonp'` parameter from your AJAX call. – Darin Dimitrov Oct 17 '13 at 07:31
but the thing is iam getting 200 success and in console if i click that error i can able able to view xml response – Vignesh Oct 17 '13 at 07:32
Then maybe the server already supports CORS. Try removing the `dataType: 'jsonp'` parameter. Also change the `contentType` parameter. – Darin Dimitrov Oct 17 '13 at 07:33
don't specify dataType parameter, remove that is that you are saying – Vignesh Oct 17 '13 at 07:36
