要有条件地注册脚本/样式，如果页面有某个块，您可以按照@将在来自similar question. 复制/粘贴，并对该问题进行一些修改：

add_action( \'enqueue_block_assets\', \'myplugin_enqueue_if_block_is_present\' ); // Can only be loaded in the footer
// add_action( \'wp_enqueue_scripts\', \'myplugin_enqueue_if_block_is_present\' ); // Can be loaded in the both in head and footer
function myplugin_enqueue_if_block_is_present(){

    if ( has_block( \'my-plugin/my-block\' ) ) {
        wp_enqueue_script(
            \'myplugin_script\',
            PATH_TO_ASSETS_FOLDER . \'frontend-script.js\',
            array(),
            \'1.0.0\',
            true
        );
    }
}

Beware 尽管这样做有效，但我们将enqueue函数与render回调混合使用。另一个缺点是，当回调运行时，我们已经在帖子的内容中了。这意味着我们只能在页脚排队，而不能在头部排队。

add_action( \'init\', \'myplugin_register_block\' );
function myplugin_register_block() {

    register_block_type(
        \'my-plugin/my-block\',
        array(
            \'editor_script\'   => PATH_TO_ASSETS_FOLDER . \'editor-script.js\',
            \'render_callback\' => \'myplugin_render_callback\'
        )
    );
}

function myplugin_render_callback( $attributes, $content ) {

    // Do not enqueue if we are in the editor.
    // This will depend on your use case.
    if ( is_admin() ) {
        return $content;
    }

    wp_enqueue_style(
        \'myplugin_style\',
        PATH_TO_ASSETS_FOLDER . $attributes[\'some_attribute\'] . \'-style.css\',
        array(),
        \'1.0.0\'
    );

    return $content;
}
