Temat: Dziwne zachowanie js w ie?
Niestety nic z tego - znaczy (nie)działa tak jak poprzednio - z alertem linjkę wcześniej jest oki, ale bez niestety nie.
Poniżej kod - nieco długi i niezmiernie chaotyczny, ale js nie jest moim konikiem i raczej toczę boje, żeby kod działał poprawnie.
Raz jeszcze dzięki za poświęcony czas.
