Javascript FullCalendar定期事件数组

javascript php jquery fullcalendar

Javascript FullCalendar定期事件数组,javascript,php,jquery,fullcalendar,recurring-events,Javascript,Php,Jquery,Fullcalendar,Recurring Events,我正在为fullcalendar开发定期事件后端，遇到了一个奇怪的问题 我的事件在名为events.php的页面上计算。日历显示在index.php上，并从events.php调用事件。events.php上的My函数为定期事件输出正确的字符串，但index.php上的日历仅显示每次定期事件中的第一个事件。但是，如果我复制数组生成的字符串并将其直接粘贴到events.php页面并注释掉render_fccalendar_events（）；函数，并在生成字符串的events.php末尾，日历将正确

我正在为fullcalendar开发定期事件后端，遇到了一个奇怪的问题

我的事件在名为events.php的页面上计算。日历显示在index.php上，并从events.php调用事件。events.php上的My函数为定期事件输出正确的字符串，但index.php上的日历仅显示每次定期事件中的第一个事件。但是，如果我复制数组生成的字符串并将其直接粘贴到events.php页面并注释掉render_fccalendar_events（）；函数，并在生成字符串的events.php末尾，日历将正确显示所有重复发生的事件。从我看到的函数输出，以及我粘贴到页面中的内容，都在index.php上为日历提供完全相同的内容。显然有一些不同，虽然因为它不是渲染他们相同。你知道这到底是怎么回事吗

这是events.php代码：

这是调用events.php输出的index.php代码：

   $(document).ready(function() {

                center: 'title',

            },
            defaultDate: '<?php echo date('Y-m-d'); ?>',
            editable: true,
            events:  {

$（文档）.ready（函数（）{

如果仅呈现第一个事件，则您可能在
process\u event（）
中遇到问题，它应该
返回$output而是
render_json（$output）。您能否确保在该函数中，
$queue
为
true
？$queue为false。将其更改为true，但最终结果没有差异。
