HTMLTextAreaElement: readOnly-Eigenschaft

Die readOnly-Eigenschaft der HTMLTextAreaElement-Schnittstelle gibt an, dass der Benutzer den Wert des Steuerelements nicht ändern kann. Im Gegensatz zum disabled-Attribut verhindert das readonly-Attribut nicht, dass der Benutzer das Steuerelement anklickt oder darin eine Auswahl trifft. Es spiegelt das readonly-Attribut des </code></a>-Elements wider.</p></div><section aria-labelledby="wert"><h2 id="wert"><a
