当AJAX在模板部件中调用get\\u theme\\u mod时，是否可以在自定义程序预览窗格中刷新后使其工作？

我有一个主题，可以加载滚动（无限滚动）上的帖子，除了没有在定制器预览中输出更新的主题mods外，其他一切都正常。当我点击保存按钮时，它只输出新的主题mods。

你知道如何在刷新后进行更新吗？

My control settings:

\'id\'        => \'show_caption\',
\'type\'      => \'select\',
\'section\'   => \'caption\',
\'transport\' => \'refresh\',
\'default\'   => \'top\',
\'choices\'   => array(
  \'top\'    => __( \'Top\', \'my-domain\' ),
  \'bottom\' => __( \'Bottom\', \'my-domain\' ),
),

InfiniteScroll.php:

class InfiniteScroll {

  private $query;

  public function __construct( WP_Query $query ) {
    $this->query = $query;
  }
  
  public function register() {
    add_action( \'wp_ajax_my_infinite_scroll\', array( $this, \'handleAjax\' ) );
    add_action( \'wp_ajax_nopriv_my_infinite_scroll\', array( $this, \'handleAjax\' ) );
    add_action( \'wp_enqueue_scripts\', array( $this, \'enqueueScripts\' ) );
  }

  public function getPosts() {
    ob_start();

    $this->query->query( $this->getData() );

    if ( $this->query->have_posts() ) {
      while ( $this->query->have_posts() ) {
        $this->query->the_post();
        get_template_part( \'template-parts/post/content\' );
      }
    }

    wp_reset_postdata();

    return ob_get_clean();
  }

  public function handleAjax() {
    if ( ! check_ajax_referer( \'infinite-scroll-ajax\', \'nonce\' ) ) {
      wp_die();
    }

    wp_send_json_success( $this->getPosts() );

    wp_die();
  }
  
  // ...

}

content.php:

echo get_theme_mod( \'show_caption\', \'top\' );
