У меня есть таблица со статическими данными, я уже закончил функции редактирования и сохранения.По сути, основная функция кода заключается в том, что при нажатии на 1-ю строку (предположим, что в таблице пять строк) данные из нее будут помещены внутрь в соответствующие поля ввода, и пользователь сможет редактировать, сохранять, отменять изменения вэти значения строки.Проблема в том, что я не знаю, как отменить изменения внутри поля ввода при нажатии кнопки «Отмена».Я поставлю код и пример сценария.
Sampl Scecnario, если я щелкну по первой строке, она будет заполнена внутри поля ввода (например, я отредактирую регистр отдела №: 123-12345-1234-382 до 123) и нажму "Отмена", следует вернуться к123-12345-1234-382, логика отмены заключается в том, что она должна отображать последнее сохраненное значение в строке.
Это HTML-таблица
