javascript - jQuery AJAX return the function as data upon success -

i have codeigniter flashdata + jquery ajax call show it. code:

<script type="application/javascript">  var res_no = '<?php echo $this->session->flashdata('res_no'); ?>'; var res_new = '<?php echo $this->session->flashdata('res_new'); ?>';  (function( $ ) {  $("#check-reservations").click(function() {     $.ajax({             type: "post",             url: "mycontroller/function",             async: true,             data: {             res_no: res_no,             res_new: res_new             },             success: function(data) {                if(data) {             alert(data);             }            }         });      });  /* default notifications */ $('#check-reservations').show(function() {      if (res_no) {     new pnotify({         title: 'hmm no new reservations..',         text: res_no,         type: 'custom',         addclass: 'notification-primary',         icon: 'fa fa-info-circle '     });     }      else if (res_new) {     new pnotify({         title: 'there\'s new!',         text: res_new,         type: 'custom',         addclass: 'notification-success',         icon: 'fa fa-check'     });     }    });    }).apply( this, [ jquery ]);  </script> 

inside $.ajax data, have added both

res_no: res_no, res_new: res_new 

which strings text, upon success retrive alert text. want

new pnotify({         title: 'hmm no new reservations..',         text: res_no,         type: 'custom',         addclass: 'notification-primary',         icon: 'fa fa-info-circle '     }); 

php:

 /**     * @filtered_reservations     * @index     */     $filtered_reservations = $this->filter_array($reservations);               if (count($filtered_reservations) > 0) {     foreach ($filtered_reservations $index => $reservation) {     $this->db->insert('reservations', $reservation);        } // end foreach        return $this->session->set_flashdata('res_new', "success ". count($filtered_reservations) ." reservations inserted!");      print "success ". count($filtered_reservations) ." reservations inserted!";     print "reservations: ". count($kigores_id) ." found on kigo!";     } /* end if */       /**     * @filtered_reservations     * equal 0     */     elseif (count($filtered_reservations) === 0) {     print "sorry no new reservations!";     return $this->session->set_flashdata('res_no', 'sorry no new reservations!');     //$this->ci_alerts->set('warning', "sorry no new reservations!");     }      } /* end reservations */      

what should write in data? solution found far window.reload show me notification want refresh..

in order happen, need place this:

$('#check-reservations').show(function() {     if (res_no) {         new pnotify({             title: 'hmm no new reservations..',             text: res_no,             type: 'custom',             addclass: 'notification-primary',             icon: 'fa fa-info-circle '         });     } else if (res_new) {         new pnotify({             title: 'there\'s new!',             text: res_new,             type: 'custom',             addclass: 'notification-success',             icon: 'fa fa-check'         });     } }); 

inside ajax success results, this:

$.ajax({     type: "post",     url: "mycontroller/function",     async: true,     data: {         res_no: res_no,         res_new: res_new     },     success: function(data) {            if(data) {             $('#check-reservations').show(function() {                 if (res_no) {                     new pnotify({                         title: 'hmm no new reservations..',                         text: res_no,                         type: 'custom',                         addclass: 'notification-primary',                         icon: 'fa fa-info-circle '                     });                 } else if (res_new) {                     new pnotify({                         title: 'there\'s new!',                         text: res_new,                         type: 'custom',                         addclass: 'notification-success',                         icon: 'fa fa-check'                     });                      }             });         }     } });
