error callback with {"readyState":4,"status":200,"statusText":"success"}

I have this url call. the url returns a json object as expected (direct browser call) but when I do that via ajax with the follow lines

$.ajax({
       url: url, 
       type: "GET",
       dataType:"jsonp",   
       success: function(data) {
          alert(data);
       },
       error : function(error) {
          alert("no good "+JSON.stringify(error));
       }
});

it returns me

no good {"readyState":4,"status":200,"statusText":"success"}

I know there's others similar questions on stackoverflow, but nobody seems solved it.

I've just had the exact same issue,{"readyState":4,"status":200,"statusText":"success"}

it was because I forgot to remove in my php script an echo "hello"; statment which I previously made for testing reasons, so my php script was sending a string along with JSON, that was my silly mistake maybe You have got the same too

these changes solved my problem.

//Server side

echo $_GET['callback'] . '('.json_encode($data_to_encode).')';

//js

$.ajax({
       url: url+"?callback=?", 
       type: "GET",
       dataType:"jsonp",   
       success: function(data) {
          alert(data);
       },
       error : function(error) {
          alert("no good "+JSON.stringify(error));
       }
});

That suggests that the HTTP request was successful but the attempt to parse the data was not.

i.e. that the data was not formatted as JSONP.
