尊敬的Wordpress插件开发人员同事：，

我目前正在开发一个WordPress定制预订插件。在这个插件中，我添加了一个日历短代码，它在页面上嵌入了一个Html月历。我还添加了一些Jquery，当用户单击相应的按钮时，这些Jquery应该会得到上个月或下个月的日历。jquery向管理ajax发送post请求。php，这将触发一个添加的ajax操作。唯一的问题是管理ajax。php返回400，这意味着它找不到操作。我知道会触发Wp\\u Lbs\\u日历的构造函数（这意味着必须添加操作），因为show函数成功地将日历返回到页面。

所以我希望你们能进一步帮助我。

我的代码：

日历类别：

class Wp_Lbs_Calendar {  

/**
 * The ID of this plugin.
 *
 * @since    1.0.0
 * @access   private
 * @var      string    $plugin_name    The ID of this plugin.
 */
private $plugin_name;

/**
 * The version of this plugin.
 *
 * @since    1.0.0
 * @access   private
 * @var      string    $version    The current version of this plugin.
 */
private $version;


/**
