您可以使用wp_localize_script() 要将JavaScript变量传递给编辑器，请执行以下操作：

$asset_file = include(get_template_directory() . \'/path/to/blocks/index.asset.php\');

wp_register_script(
    \'pb-theme-blocks\',
    get_template_directory_uri() . \'/path/to/blocks/index.js\',
    $asset_file[\'dependencies\'],
    $asset_file[\'version\']
);

wp_localize_script(
    \'pb-theme-blocks\',
    \'pbThemeBlocksVars\',
    array(
        \'classes\' => array(), // Your theme classes go here
    )
);

const classes = pbThemeBlocksVars.classes;
