Fullcalendar不显示codeigniter文件

Question

我的观点load.php：

<?php

$all = $this->db->get_where('project', array('institution_id' => $this->session->userdata('institution_id')))->result_array();

$data = array();

foreach($all as $row)
{
 $data[] = array(
  'id'   => $row["project_code"],
  'title'   => $row["description"],
  'start'   => date('d-M-Y H:i:s', $row["timestamp_start"]),
  'end'   => date('d-M-Y H:i:s', $row["timestamp_end"])
 );
}

echo json_encode($data);

?>

但是，它不会显示我的Fullcalendar。这是在：

 events: 'https://xxxxxxx.com.au/index.php?staff/load/',

您请求的视图。事件是从load.php获得的，这是在这篇文章的开头。

<div id="calendar" class="fc-calendar"></div>

  <script>

  $(document).ready(function() {
   var calendar = $('#calendar').fullCalendar({
    editable:true,
    header:{
     left:'prev,next today',
     center:'title',
     right:'month,agendaWeek,agendaDay'
    },
    events: 'https://panel.strater.com.au/index.php?staff/load/',

   });
  });

  </script>
