Как я могу предотвратить исчезновение внешнего вида jQuery UI после отправки / обратной передачи формы?
У меня есть JSF (Mojarra) v2.1.11, Primefaces v3.4.2, веб-приложение Java 6, использующее средство выбора даты jQuery. Я использую селектор, который выглядит примерно так:
$('#form1\\:dp').datepicker({showOn: 'button', buttonText: "Choose"});
Это позволяет пользователю нажать кнопку, чтобы вызвать средство выбора даты. Вопрос яЯ имею, что "кнопка» исчезаетпосле пользователь отправляет форму. Видимо, "кнопка» загружается только один раз, когда страница изначально загружена. Я'хотел бы знать, как(что такое лучшая практика) чтобы сохранить JQuery DatePicker "кнопка» между представлениями / постбэками.
