Cross domain Ajax Call

Question

While calling MVC webservice from my html page it was always going to error; please help me

$.ajax({ type: "GET", url: url, contentType: "application/json; charset=utf-8", crossDomain: true, dataType: "json", success: function (msg) { alert(Response.ErrorMessage ) }, error: function (e, status) { alert(e + " Fail " + status) } });

have you tried dataType : "jsonp" ? which error message you get? — MaiKaY

you don't need crossDomain: true, or contentType: "application/json; charset=utf-8", — user400654

Start by opening your javascript debugging console and looking for error messages. Next, still within your javascript debugging console, look at the network requests that took place to see if your server returned what you expected it to. — user400654

You have to setup CORS (http://www.html5rocks.com/en/tutorials/cors/) or use JSONP. If you decide to use JSONP then you have to send proper callback function name with JSON data.

To complement this answer: If you want to use JSONP, please also have a look at the possible security concerns of it...

Yea, you should use CORS if it is viable option for you.
