Codeigniter JQuery load data in view dynamically after jquery .get request

Question

I have been thinkering around and I cant get it to work. So i have a Jquery function which after input field onblur event posts new discount value in database.

JQuery:

    function saveAtlProc(t){
    pzid = $('#pzrows').attr('rel');
    atl_proc = $(t).val();
    var site_url = document.getElementById("site_url").value;
     $.post(site_url, {
            pzid : pzid,
            atl_proc : atl_proc,
            site_url : site_url
        },
        function(rawdata){
             getPZtotals();
        });
}

This works and is okey, the problem starts with getPZtotals(),

getPZtotals() JQuery:

function getPZtotals(){
pzid = $('#pzrows').attr('rel');
var site_url = document.getElementById("pvn_rates_get").value;
$.get(site_url, {
        pzid : pzid
    },
    function(rawdata){
     var pieg_nos = rawdata.pieg_nos;
        alert(pieg_nos);
});
}

Alert function shows that the variable is undefined. And i cant figure out why.

This is what is returned in .get() inspecting it with firebug

I think that this is correct and there shouldnt be any problems.

MY Controller: which returns data in .get() function

  public function get_new_discounts(){
    $this->load->model('offers_for_clients_model');
    $id = trim($_GET['pzid']);
    $data['orders_info'] =  $this->offers_for_clients_model->get_offers_info($id);
    $this->output->set_output(json_encode($data['orders_info']));
    /*echo ();*/
}

Model:

function get_offers_info($id){
    $query = $this->db->where('ID', $id)->get('pz_pied')->result();
    return $query;
}

I googled it but couldn`t find anything similar to this.

Answer 1

Your php model is returning an outer array wrapping the object data you are trying to access in your alert.

Try:

 var pieg_nos = rawdata[0].pieg_nos;
 alert(pieg_nos);

Answer 2

This worked:

var myObject = JSON.parse(rawdata);
alert(myObject[0].pieg_nos);
