    dataType: "jsonp",
    crossDomain: true,
    success: function (responseString) {
        alert(responseString);

        var errorMessage = exception || xhr.statusText;
        alert(errorMessage);
    }

i'm trying to make an cross domain call and getting error

jQuery180014405992737595236_1357861668479 was not called

Update

Well i tried to use dataType:"json" but at that point getting error

No Transport

Answer 1

That suggests either a network error or an end point that doesn't return a JSONP response.

(I'm guessing the DNS lookup failure I get when testing it is because that isn't your real URL (please use example.com for example URLs, that is what it is there for) if not, then that is your problem).

Answer 2

It's an incorrect JSONP Response. The server needs to process the callback=nameOfCallbackFunction argument of the GET Request and serve it as a function wrapper.

The proper response then should look like this:

nameOfCallbackFunction({"yourjson": "here"});
