jQuery AJAX JSON parseerror

Question

I've got a webpage with an AJAX request using jQuery and dataType=json

$.ajax({
 type: "POST",
 url: 'api/',
 data: post,
 success: function(data) {}
 dataType: 'json',
 error: function(jqXHR, textStatus, errorThrown) {
  var message = myprint(errorThrown)+myprint(textStatus)+myprint(jqXHR);
  // myprint is a custom print function
  alert(message);
 }
}

About 1% of the time, I got this alert :

{}
"parsererror"
{
 "readyState": 4,
 "responseText": "{\"results\":[\"TEST1\",\"TEST2\"],\"time\":\"0,123\"}",
 "status": 200,
 "statusText": "OK"
}

Clearly there is no parseerror. Do you have any idea that I might check ? Thank you.

Answer 1

Error: "showing-json parse error" that mean: data format response from server incorrect .

In client, you set dataType is 'json' but into data response is not json data or may be xml (i not sure, you should check again).
