Этот следующий javascript вызывает нежелательную обратную передачу в коде веб-формы asp.net:
mini_cal.on("click, focusin", ".a-date", function(){
if(!$(this).hasClass('blurred'))
showEvent($(this).data('event'));
});`
Это из элемента управления календаря, и функция вызывается при нажатии на дату.Добавление e.preventDefault () останавливает обратную передачу, но затем showEvent () не вызывается.На простой HTML-странице все работает нормально, но мне нужно это на странице aspx, потому что мне нужно получить события со стороны базы данных на стороне сервера.Я надеюсь, что кто-то может найти решение, поскольку сам автор, похоже, не может его найти.
Хорошо, вот страница aspx:
