Error handling in getJSON call using jQuery

You can  handle errors in a getJSON calls .There are two ways to handle errors

1) Configuring your Ajax calls before actually calling(Recommended way)
2) Specifically (with method chain).
 
In this post i would like to give a example on First method.It is preferred way to handle the errors.In the example code i have used alert to display

error status ,error thrown, response text thrown by server.You can only display status or Response test based on your requirement
  

Example Code:

$(document).ready(function () {

            $(document).ready(function () {

                $.ajaxSetup({ "error": function (XMLHttpRequest, textStatus, errorThrown) {

                    alert(textStatus);

                    alert(errorThrown);

                    alert(XMLHttpRequest.responseText);

                }

                });

           // Write your Getjson call here.

           //Ex: 

           // $("#ddlCountry").change(function () {
