i use this

returning json from controller

Code:

$x = $this->input->post('x');
echo json_encode(array("datacallback" => array("1" => $x)));

if result as row

Code:

$.ajax({
                        type: "POST",
                        url: //url target,
                        data: {x  : "abc"},//to add more ada
                        dataType: "json"
                    }).done(function(data){
var x = data.datacallback.1;
}

x will contain abc

if you need to loop trough returned json use this

Code:

$.each(data.datacallback, function(k, item) {
                    alert (item.arraykeyname)
                });
