Jquery Not Showing Json Data From WCF

Question

I have Written A Simple WCF Method.It is returning Correct values But It is showing 200

    $.ajax({
        url: "http://localhost:60770/Service.svc/GetContacts?calback=?",
        type: "POST",
        dataType: "JSON",
        contentType: "application/json",
        data: "{}",
        crossDomain: true,
        processdata: true,
        success: function (response) {
        //    var data = response;
            alert("data.FirstName");
        },

        error: function (e) {
            alert('error ' + e.status + ' ' + e.responseText);

        }
    });

It is going to error and when i am checking the response using FireBug. it is showing Json there.

Please Help!!

for jsonp requests dataType should be `jsonp`, type -> `get` — Musa, Mar 09 '13 at 16:48
Full error function signature is :Function( jqXHR jqXHR, String textStatus, String errorThrown ), so change it and read errorThrown — Nenad, Mar 09 '13 at 16:50
When i added a Full error function,it still returns undefined — user1657868, Mar 09 '13 at 16:54

It looks like you're mixing JSON and JSONP here.

You have crossDomain:true, absolute URL, but pointing to local host. Then you have typo in example ?calback=? (missing "l" and 2nd "?").

In JSONP your:

/GetContacts?calback=myFunction

you expect result like: myFunction({"d":"Hello"})

myFunction will be called automatically. In your case "?" is name of the function. And WCF, .NET 4 it supports JSONP, but you have to enable it: How to natively enable JSONP for existing WCF service?

So I would switch-off crossDomain:true and provide relative url without callback parameter, or read a bit on JSONP: What is JSONP all about?
