javascript - Displaying returned json data from controller with AJAX -

-

i trying send post submission controller, , want receive json string can append information table. here's have far:

my ajax call:

$('#addticketbutton').click(function(){       $.ajax({           type:'post',           url:'<?php echo site_url();?>ticket_system/add_ticket',           data:{               'headline': $("#headline").val(),               'description': $('#description').val(),               'category': $('#category').val(),               'priority': $('#priority').val(),               'assigned': $('#assign').val()           },           datatype: 'json',           success: function(data){             $("#created_table > tbody:last-child").append("<tr><td>" + data[0].ticketid + "</td><td>" + $("#headline").val() + "</td><td>" + data[0].lastupdated + "</td></tr>");           }       }); });

my controller:

public function add_ticket() {     $ticket = array(         'headline' => $this->input->post('headline'),         'description' => $this->input->post('description'),         'category' => $this->input->post('category'),         'priority' => $this->input->post('priority'),         'assigned' => $this->input->post('assigned'),         'userid' => $this->userid     );     $ticketid = $this->tickets->addticket($ticket);     $ticket = $this->tickets->getticketbyticketid($ticketid);     $success = array(         'ticketid' => $ticketid,         'lastupdated' => date("m d, y h:i a")     );       echo json_encode($success); }

i have tried using:

 data.ticketid

but didn't work either.

any me appreciated. thank you!

not sure, can try this:

controller:

$success = json_encode($ticketid||date("m d, y h:i a")); //added '||' between results

ajax :

d =  data.split("||"); //break results $("#created_table > tbody:last-child").append("<tr><td>" + d[0] + "</td><td>" + $("#headline").val() + "</td><td>" + d[1] + "</td></tr>");
