Working with JSON objects in JavaScript using CodeIgniter framework

I am encountering an issue with my Jquery function in the controller. It seems to be unable to read the Json_encoded object, even though I am using codeigniter. Any ideas why?

 $(this).ajaxSubmit({ 
                    type : "POST",
                    url: '../index.php/user/signin',   // target element(s) to be updated with server response 
                    cache : false,
                    dataType:'json',
                    success : function(data){ 
                        data = $.trim(data);
                        alert(data);
                        var obj = jQuery.parseJSON(data);

                        alert(obj.Condition);
                    },
                    error: function(){

                    }

Controller

$arr = array('Condition' => $condition, 'Message' => $msg);

// header('Content-Type: application/json');
echo json_encode($arr); 

Answer №1

Consider utilizing the eval method instead of parseJSON

Within JavaScript:

  $(this).ajaxSubmit({ 
                type : "POST",
                url: '../index.php/user/signin',   // update target element(s) with server response 
                cache : false,
                dataType:'json',
                success : function(data){ 
                    alert(data);
                    var obj = eval('(' + data+ ')');

                    alert(obj.Condition);
                },
                error: function(){

                }

It may not be necessary to use $.trim to process the response data

Answer №2

Give it a shot

url: <?=site_url('user/signin')?>,

If you're not sending data, jquery getjson is the way to go.

http://api.jquery.com/jQuery.getJSON/

It's smooth sailing.

Check the browser console for any potential errors and let me know.
