Ошибка в ajax
09.05.2018, 11:58. Показов 559. Ответов 3
Добрый день!я пишу авторизацию для сайта.Есть файл авторизации,где я проверяю на допустимые символы и длину,если все хорошо, то я отправляю ajax запрос на файл,где идет подключение к БД и проверяется логин и пароль.Если все ок,возвращается массив с котором написано все ок,если нет,то тоже возвращается массив,в котором написаны ошибки.Ноу меня ajax не хочет работать.Я все проверил без ajax,все идеально работает без ajax,но через ajax ошибка возникает.я не знаю почему,помогите пожалуйста,бьюсь уже 2 часа.
