Staram sie wyedytowac skrypt na moje potrzeby aby miec dynamiczne select menu tzn po wybraniu pierwszego lista drugiego menu zmienia sie zgodnie z ukladem xml.
Chyba utknalem przy parsowaniu tych danych gdzie sa polskie znaki. W bazie danych uzywam cp1250.
W firefoxie dziala mi wybieranie jesli w selecie nie ma polskiego znaku a w IE dziala jedna z 10 opcji jakie sa i zwraca jakis blad null jest pusty lub nie jest obiektem.
Jak podefiniowac te strony kodowe zeby sie wszystko rozumialo?
Main:
