I have an ajax call as follows-

this.send({
    url : AppConstants.variables.callURL.feed,
    data : rqStr,
    onSuccess : function(data, textStatus) {
           console.log(textStatus);
});

send : function(obj) {
    this.callbackObj = obj;
    FeedBackPanel.add(obj.url + "->" + obj.data);
    $.ajax({
        url : obj.url,
        data : obj.data,
        dataType : "jsonp",
        jsonp : "callback",
        jsonpCallback: "RequestController.callbackObj.onSuccess"
    });
}

It works fine>however i am trying to provide a wrong domain and in that case i get a

• By catching the status code I mean just obtain the 504 value.I have my own mechanism to deal with it. – Mayur Buragohain Commented Dec 31, 2013 at 10:08
• 2 You need an error callback, but as it is a cross domain request using jsonp you can only find out that the request had a timeout but you cannot figure out the status code due the way jsonp requests work. – t.niese Commented Dec 31, 2013 at 10:11
• how do i find out it had a timeout programatically? – Mayur Buragohain Commented Dec 31, 2013 at 10:13

Due to the way jsonp requests works, you are not able to find out if a request failed and why.

What you can do is to set a timeout yourself for the jsonp request. If you don't get a valid response in that time, the error callback is called.

You need to figure out yourself what value you want to set for the timeout, because if e.g. the time required for sending the request, building the response and sending it back takes 500ms and you set the timeout to 100ms, the error callback will be called all the time, even if the request itself did not timeout.

$.ajax({
  url : obj.url,
  data : obj.data,
  dataType : "jsonp",
  jsonp : "callback",
  timeout:300,
  jsonpCallback: "RequestController.callbackObj.onSuccess"
}).success(function() {
  console.log('test')
}).error(function() {
  console.log("error");
});
