不需要库，它很容易实现。如果您正在编写自己的插件（看起来您是），那么您可以以一种相当轻量级的方式来完成这项工作：

通知的略微修改版本，在显示之前检查通知是否已被取消，并将通知的“类型”存储在标记中，以便在javascript中访问：

function prefix_deprecated_hook_admin_notice() {
    if ( has_filter( \'prefix_filter\' ) ) { 
        // Check if it\'s been dismissed...
        if ( ! get_option(\'dismissed-prefix_deprecated\', FALSE ) ) { 
            // Added the class "notice-my-class" so jQuery pick it up and pass via AJAX,
            // and added "data-notice" attribute in order to track multiple / different notices
            // multiple dismissible notice states ?>
            <div class="updated notice notice-my-class is-dismissible" data-notice="prefix_deprecated">
                <p><?php _e( \'Notice\', \'my-text-domain\' ); ?></p>
            </div>
        <?php }
    }
}

add_action( \'admin_notices\', \'prefix_deprecated_hook_admin_notice\' );

  // shorthand no-conflict safe document-ready function
  jQuery(function($) {
    // Hook into the "notice-my-class" class we added to the notice, so
    // Only listen to YOUR notices being dismissed
    $( document ).on( \'click\', \'.notice-my-class .notice-dismiss\', function () {
        // Read the "data-notice" information to track which notice
        // is being dismissed and send it via AJAX
        var type = $( this ).closest( \'.notice-my-class\' ).data( \'notice\' );
        // Make an AJAX call
        // Since WP 2.8 ajaxurl is always defined in the admin header and points to admin-ajax.php
        $.ajax( ajaxurl,
          {
            type: \'POST\',
            data: {
              action: \'dismissed_notice_handler\',
              type: type,
            }
          } );
      } );
  });

add_action( \'wp_ajax_dismissed_notice_handler\', \'ajax_notice_handler\' );

/**
 * AJAX handler to store the state of dismissible notices.
 */
function ajax_notice_handler() {
    // Pick up the notice "type" - passed via jQuery (the "data-notice" attribute on the notice)
    $type = self::request( \'type\' );
    // Store it in the options table
    update_option( \'dismissed-\' . $type, TRUE );
}

我找到的最佳解决方案是一个小型图书馆。https://github.com/CalderaWP/dismissible_notice

在WordPress 3.8之前，它是向后兼容的。
