Form validering: Form submitter trods alert om fejl i registreringen
Kaere eksperter,Jeg har en form, hvor folk skal udfylde info om sig selv, plus vaelge minimum 3 interesser fra checkboxes.
At folk vaelger minimum 3 interesser blir valideret med javascript, og det virker egentlig fint nok.
Men samtidig vil jeg ogsaa gerne validere at de andre felter i formen er udfyldt, hvis ikke skal scriptet alerte med en fejlbesked. Hvis man ikke udfylder de paakraevede felter alerter scriptet fint nok, men fortsaetter saa alligvel og submitter formen, hvilket jo ik er meningen.
Kode pasted nedenunder. Kan nogen se hvor den er gal? Paa forhaand mange tak.
