В приведенном ниже коде я использую поле ретранслятора для хранения ссылок и рангов изображения. В интерфейсе я пытаюсь реализовать что-то вроде этого: когда я выбираю другой ранг для изображения и нажимаю кнопку update rank , страница должна обновить ранг в базе данных и перезагрузить страницу с новым рангом. Тем не менее, код удаляет ранг полностью при нажатии любой кнопки. При обнаружении неисправностей я обнаружил, что document.write не передает значения функции. Ниже приведен мой код:
