在我的wp-contents/pugins文件夹中，我有program-registration。在这个插件中，我有js/registration.js和css/registration.css。
为什么无法访问此js文件中定义的函数？

要在wordpress管理面板插件设置中加载js和css文件，我们需要像这样调用admin_enqueue_scripts，
所以这就是，
function registration_scripts() {
wp_register_script('registrationjs_init', plugins_url('js/registration.js', __FILE__));
wp_enqueue_script('registrationjs_init');
}
add_action( 'admin_enqueue_scripts', 'registration_scripts' );
