You need to do some work on server side. I see you are using PHP on server side, but solution for .NET web application is here: Cannot set content-type to 'application/json' in jQuery.ajax

Do the same in PHP script and it will work. Simply: At first request browser is asking server if is allowed to send such data with such type and second request is the proper/allowed.

I was looking through source 1.3.2, when using JSONP, the request is made by building a SCRIPT element dynamically, which gets past the browsers Same-domain policy. Naturally, you can't make a POST request using a SCRIPT element, the browser would fetch the result using GET.

As you are requesting a JSONP call, the SCRIPT element is not generated, because it only does this when the Type of AJAX call is set to GET.
