jQuery $ .ajax jsonp解析器错误

Question

I looked through all the .ajax jsonp parsererror in stackoverflow and still couldn't figure how to get rid of this error.

JSONP Error: parsererror Error: jQuery21108956659331452101_1444622439301 was not called
JSONP was retrieved successfully

It was retrieved successfully and still not clear why I am getting the parsererror. Codes below. Any help would be greatly appreciated!

$.ajax(this.dataSrc, {
    type: "GET",
    dataType: "jsonp",
    jsonp: "callback",
    error: function(xhr, status, error) {
        console.log('JSONP Error: ' + status + error);
    },
    complete: function(xhr, status) {
        console.log('JSONP was retrieved successfully');
    }
});
