Hej,
mam prosty formularz na którym mam "I accept the terms..." i teraz jeśli user tego nie zaznaczy to wyskakuje mu error (czerwone kółeczko obok checkBox-a), no i problem jest taki że jak już zaznaczy to to kółeczko nie znika...
Jak to u mnie jest zrobione:
globalna zmienna Accept = false;
funkcja do akcji kliknięcia tego Checkboxa która ustawia Accept = true;
funkcja która sprawdza czy wszystkie pola są wypełnione - sprawdza także czy Accept = true;
a aktualizacja UI?
Pokaż kod czarów nie ma i nie można naprawić czegoś czego się nie widzi.
tak wygląda cały kod:
