我想要实现的是通过get\\u post\\u meta获取日期，并将其推送到数组中，然后将其传递到js代码中。但当我使用下面的代码时，循环中的第一篇帖子的日期会被格式化，而其他帖子的日期显示为1970年1月1日。工作时间为5小时，如有任何帮助，将不胜感激。
这是wordpress的代码。

wp_reset_postdata();

?>
<script type="text/javascript">
jQuery(document).ready(function() {

left: \'prev,next today\',

businessHours: true, // display business hours
editable: false,
events:<?php echo json_encode($event_data); ?>

});

<?php

这是输出。
