Name

Event.preventDefault( ) — Hebt die Standardaktion eines Events aufDOM Level 2 Events

Überblick

void preventDefault( );

Beschreibung

Diese Methode teilt dem Webbrowser mit, dass er eine eventuell vorhandene Standardaktion für dieses Event nicht ausführen darf. Wenn z.B. die type-Eigenschaft »submit« ist, kann jeder Event-Handler, der während einer Event-Ausbreitungsphase aufgerufen wird, das Abschicken des Formulars verhindern, indem er diese Methode aufruft. Wenn die cancelable-Eigenschaft eines Event-Objekts false ist, ist entweder gar keine Standardaktion vorhanden, oder es gibt eine Standardaktion, die sich nicht verhindern lässt. In beiden Fällen hat der Aufruf der Methode keinen Effekt.
