Ich versuche, eine angemessene Menge an Validierung mit indexOf
zu erstellen.Javascript indexOf gibt kein Ergebnis zurück
save()
ist ein onclick
Attribut für eine Schaltfläche.
saveDirectionsForm
ist die id
einer Texteingabe.
result
ist die id
eines leeren Absatzes.
Dies ist mein Code so weit. Warum wird nichts gerendert, wenn ich auf save()
klicke?

Welchen Wert überprüfen Sie? – Grundy
'saveDirectionsForm' scheint wie dies ist eine Formular-ID, müssen Sie die E-Mail-Feld-ID verwenden –
ist die ID des Feldes INPUT: ** saveDirectionsForm **? –
