我正在创建自定义 Gutenberg 编辑器块以将 YouTube 视频 ID 设置为<button>属性data-video=""

更新 - 在下面添加了工作代码

我的function.php代码

// Include Css and js block files
function designa_youtube_block() {
    // Scripts
    wp_register_script(
        'youtube-block-script', // Handle.
         '/wp-content/themes/twentyfifteen/init/block.js',
        array( 'wp-blocks', 'wp-element', 'wp-i18n' ),
        time()
    );
    // Styles
    wp_register_style(
        'youtube-block-editor-style', // Handle.
        '/wp-content/themes/twentyfifteen/init/editor.css',
        array( 'wp-edit-blocks' ),
        time()
    );
    // Register the block with WP using our namespacing
    register_block_type( 'designa/youtube-block', array(
        'editor_script' => 'youtube-block-script',
        'editor_style' => 'youtube-block-editor-style',
    ) );

}
add_action( 'init', 'designa_youtube_block' );

}

在后端我得到了这个结果: 在此处输入图像描述

一切正常,但现在我需要通过 ID 从 YouTube 获取视频的标题和持续时间getId(attributes.url)并插入到 InspectorControls 块。

如果我尝试使用 Ajax 获取标题和持续时间,首先将所有块字段呈现给 InspectorControls,然后执行我的 ajax 请求。我在ajax成功时需要类似的东西push( el( 'p', {}, '**YouTube Title**') )

告诉我如何在渲染和更改后将使用 Ajax 获得的信息添加到 InspectorControls?
