javascript - jQuery.ajax success callback function not executed

Question

I have a JavaScript Ajax call (jQuery.ajax), that does not execute the success callback function.

$.ajax({
        url: target,
        contentType: 'application/json; charset=utf-8',
        type: 'POST',
        // type: 'GET',
        dataType: 'jsonp',
        error: function (xhr, status) {
            alert(status);
        },
        success: function (result) {
            alert("Callback done!");
            // grid.dataBind(result.results);
            // grid.dataBind(result);
        }
    });

I see in firebug, that the request is posted and the correct result in terms of the json is returned as expected. What is wrong?

Answer 1

For many times I have encountered similar problems and most of the time the reason was a malformed json. Try getting the result as text data type to see whether this is your problem.

Also, I'd like to ask if you're using a parameter like "&jsoncallback=?" in your url, since your data type is jsonp instead of simple json.
