How to make a jsonp POST request that specifies contentType with jQuery?

Use json in dataType and send like this:

        $.ajax({            url: "your url which return json",            type: "POST",            crossDomain: true,            data: data,            dataType: "json",            success:function(result){                alert(JSON.stringify(result));            },            error:function(xhr,status,error){                alert(status);            }        });

and put this lines in your server side file:

if PHP:

header('Access-Control-Allow-Origin: *');header('Access-Control-Allow-Methods: POST');header('Access-Control-Max-Age: 1000');

if java:

response.addHeader( "Access-Control-Allow-Origin", "*" ); response.addHeader( "Access-Control-Allow-Methods", "POST" ); response.addHeader( "Access-Control-Max-Age", "1000" );
