Вот страница, на которой размещено порядка сотни элементов, это игра и я в ней сажаю и поливаю деревья, собираю урожай.
На каждом дереве есть кнопка "Собрать урожай" или "Удобрить" или "Полить"
Так вот, очень неудобно скроллить вниз страницы, нажать на одном дереве "Собрать урожай" и страница опять ползёт вверх, вернее перезагружается после записи значений в БД.
Мои попытки попытки работы с javascript привели к дублированию информации в БД, а страница всё-равно перезагружалась.
Убрал всё что наделал и решил показать профессионалам- обьясните общий подход- где куда вставлять нужно - а то я не по тому пути пошёл наверно. Знаний в этой области 0.
