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：
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？
