尽管上述库带来了高级本地化能力（最重要的是_n 函数），使用wp_localize_script() 自WordPress 2.2以来，该功能已使用多年。以下是本地化的示例Magnific Popup 脚本(source) 从我的一个网站。首先，您应该更改脚本中所有硬编码的消息（这里是jquery.magnific-popup.js 显示如何执行的脚本）：

接下来，按以下方式使用本地化脚本：

wp_enqueue_script( \'magnific-popup\', get_stylesheet_directory_uri() . \'/assets/lib/magnific-popup/magnific-popup.js\', array( \'jquery\' ) );
$magnific_popup_messages = array(
    \'close\'              => __( \'Close (Esc)\', \'your-text-domain\' ),
    \'loading\'            => __( \'Loading...\', \'your-text-domain\' ),
    \'content_not_found\'  => __( \'Content not found\', \'your-text-domain\' ),
    \'content_not_loaded\' => __( \'<a href="%url%">The content</a> could not be loaded.\', \'your-text-domain\' ),
    \'image_not_loaded\'   => __( \'<a href="%url%">The image</a> could not be loaded.\', \'your-text-domain\' ),
    \'previous\'           => __( \'Previous (Left arrow key)\', \'your-text-domain\' ),
    \'next\'               => __( \'Next (Right arrow key)\', \'your-text-domain\' ),
    \'current\'            => __( \'%curr% of %total%\', \'your-text-domain\' )
);
wp_localize_script( \'magnific-popup\', \'mfp_msg\', $magnific_popup_messages );

当您需要将一些参数传递给排队的javascript时，此函数也很有用（虽然它不是为这个目的而设计的，但这种类型的使用非常流行）。
