CodeIgniter - Ajax Json call to controller not working

Question

I am current using CodeIgniter 2.2.2 I have the following controller code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class switchLang extends CI_Controller {
    public function __construct()
    {
        parent::__construct();

                $this->load->helper('url');
    }
    public function changeLang()
    {
            log_message('debug', 'INSIDE');
            //echo "test";

            $data = array("STATUS"=>"true");
            //echo "HI";
            echo json_encode($data) ;   
    }

    public function index(){
        }   
}

And inside my view I have the following ajax call:

<script  type="text/javascript">
            $(document).ready(function() {      
                                var base_url = '<?php echo site_url('switchLang/changeLang');?>';

                                $('#lang').click(function(event) {
                                        console.log(5 + 6);
                                        $.ajax({
                    'async': false,
                    'url' : base_url,
                    'type' : 'POST', 
                    'dataType': 'json',
                    'data' : 'data',
                    'success' : function(data){ 
                                console.log(data);
                                 if(data){
                                    location.reload(); 
                                }
                             }
                                    });

                                });
                        });
</script>

I am trying to reload page on success ajax call. However I am getting only the following response in my Chrome debugger and nothing happens.

In your ajax call what value you are getting for base_url ?? — Sameer K

/switchLang/changeLang is repeating in above url. Is it the correct URL ?? — Sameer K

This is what I meant: localhost:8080/a1/switchLang/changeLang — Ryan Fung

Seems like I always have problem with the url in codeigniter. But in this case, I don't think my url is incorrect. Because I try copy and pasting the url in my browser and it is working perfectly — Ryan Fung

Try without reloading as alredy suggested. Since you are not posting anything to controller, for sake of test try with AJAX GET type to see what will be result. — Tpojka

i think there may be quotation problem change:

var base_url = '<?php echo site_url('switchLang/changeLang');?>';

to

var base_url = '<?php echo site_url("switchLang/changeLang");?>';
