Informiert darüber, dass das Element für die Bearbeitung durch den Benutzer verfügbar ist – Sie können Text löschen und einen neuen eingeben. Standardbefehle wie „Rückgängig machen“, „Text aus dem Puffer einfügen“ usw. funktionieren ebenfalls mit allen Browsern. Attribut contenteditable hat einen festen Satz von Werten, es kann eine leere Zeichenfolge sein, true oder false. Leere Zeichenfolge oder true geben an, dass das Element bearbeitet werden kann.
Bedeutung false zeigt an, dass das Element nicht bearbeitet werden kann. Es gibt auch einen dritten Staat — inherit, dies ist der Standardwert des Attributs und bedeutet, dass der Wert vom übergeordneten Element geerbt wird. Alle Nachkommen dieses Elements werden ebenfalls bearbeitbar, wenn das Attribut contenteditable sie haben es offensichtlich nicht installiert false.
contenteditable=”true | false”
true Aktiviert den Bearbeitungsmodus.
false Verhindert das Bearbeiten eines Elements.
inherit Ein Element ist bearbeitbar, wenn sein unmittelbares übergeordnetes Element bearbeitbar ist.
Anstatt true es ist akzeptabel, einen leeren Wert anzugeben (contenteditable=””) oder schreibe es überhaupt nicht (contenteditable).
