Codeigniter with ajax: success function not working

I have a problem with success function in my $.ajax function in javascript file:

$("#country select").change(function () { 
            var country_value = $(this).val(); 
            $.ajax({
                url:base_url + "Search_controller/testing_controller", 
                method: 'post',
                data: {country_val: country_value },
                dataType: 'json',
                success: function(data){
                    console.log('done : ' + data);  
                },
                   error: function (reponse) {
                console.log('Problem with ajax');
                }

            });

my Controller function 

   <?php

I find the solution is because of CSRF security

$("#country select").change(function () { 
             var country_value= $(this).val(); 
             var data = { /* params  */
                    "country": country_value,
                     "state": '001'
                };
              data[csfr_token_name] = $.cookie(csfr_cookie_name);
            $.ajax({
                url:base_url + "Search_controller/testing_controller", 
                method: 'post',
                data: data,
                dataType: 'json',
                success: function(data){
                    console.log('done : ' + data);  
                },
                   error: function (reponse) {
                console.log('Problem with ajax');
                }

            });

Change your URL as follows

url:"<?php echo base_url()?>index.php/Search_controller/testing_controller",

I tested your code and its working file.

base_url() is a Codeigniter function (php), in your $ajax function you use the javascript variable base_url, which is not defined.

in order to get the php base_url() into your $ajax function you need to echo out the php function, changing to this line:

url: "<?php echo base_url() ?>Search_controller/testing_controller",
