JQUERY JSON response triggers parse error

Question

I am trying to perform some basic operations with jquery json.

  var urlPath= encodeURIComponent('{"fields":"subject,course,unit,topic,lesson"}');
  $.ajax({

              url : 'http://abcd.org/proficiency.json?data'+urlpath,
              type : 'GET',
              dataType : 'jsonp',
              contentType: "application/json",
              success : function(data) {
              console.log("success");

              },
              error: function (XMLHttpRequest, textStatus, errorThrown) {
              console.log(XMLHttpRequest, textStatus, errorThrown);


   }
    });

The error callback is always triggers

Error... parsererror jQuery15001997238997904205_1298484897373 was not called.

How to fix it?

Thanks for reading..

Does the server actually return JSONP? Please post an example of the response. — Felix Kling, Feb 07 '14 at 05:56
why are You using contentType: "application/json" ? I think it's not needed. only dataType : 'jsonp', - will work fine. Try this. — Ripa Saha, Feb 07 '14 at 06:03

@Felix Kling: server response {"content": [{"topic": [{"22920": 0.0003933333333333333},{"22937": 0.14765555555555557},{"22881": 0.0013955555555555555}]}],"message": [],"dateRange": [{}],"paginate": {} } — Anand Rajagopal, Feb 07 '14 at 06:41
That's not JSONP, that's JSON. You cannot tell jQuery to expect JSONP if you get JSON. — Felix Kling, Feb 07 '14 at 06:42
@Felix Kling: i tried with dataType: json my server response is blank . when giving dataType: jsonp server response is {"content": [{"topic": [{"22920": 0.0003933333333333333},{"22937": 0.14765555555555557},{"22881": 0.0013955555555555555}]}],"message": [],"dateRange": [{}],"paginate": {} } — Anand Rajagopal, Feb 07 '14 at 06:44

@Felix Kling: Its triggering the error **missing ; before statement** {"content": [{"topic": [{"22920": 0.0003933333333333333},{"22937": 0.14765555555555557},{"22881": 0.0013955555555555555}]}],"message": [],"dateRange": [{}],"paginate": {} } — Anand Rajagopal, Feb 07 '14 at 08:55

The server is giving back invalid JSON, there is an extra }] and a missing ,. It should be changed to this:

{
    "content": [
        {
            "topic": [
                {
                    "22920": 0.0003933333333333333
                },
                {
                    "22937": 0.14765555555555557
                },
                {
                    "22881": 0.0013955555555555555
                }
            ]
        }
    ],
    "message": [],
    "dateRange": [
        {}
    ],
    "paginate": {}
}
