Здесь, в моем коде, я пытаюсь перезагрузить страницу при нажатии кнопки ОК. Но это не работает. Как я могу изменить страницу на кнопку ОК, это написано на той же странице, которую я должен перезагрузить. В моем коде я спою форму и compont поля ввода для моего экрана входа в систему. Весь код там ниже. Я пытаюсь, чтобы, когда я получаю любой ответ, как неправильное имя пользователя и пароль в alere, тогда кнопка ОК, я должен очистить свое поле формы. Пока вот это не радует. Для этого я удаляю свою ценность вручную. Пожалуйста, добавьте.
