Hinweise

Klicken Sie im Menü Bearbeitenoder Quick Access-MenüWebsiteaktionen Menü verschiedene Aktionen dem Benutzer angezeigt. Jede dieser Menüs enthält eine Instanz des ConsoleDataSource -Objekts, das eine hierarchische Auflistung von ConsoleNode -Objekten enthält, von denen einige die ConsoleAction -Klasse implementiert. Jede Implementierung dieser Klasse stellt eine bestimmte Aktion, z. B. Erstellen, Veröffentlichen, Versionsverlauf anzeigenoder Speichern und Bearbeitung beenden.

Das hier vorgestellte Codebeispiel wurde vereinfacht, aber zeigt, wie eine Konsole Aktion erstellt werden soll. Ausführen dieser Beispielanwendung wird eine Schaltfläche "Speichern und Bearbeitung beenden" Quick Access-Menühinzugefügt. Ist es erforderlich, dass die Seite im Bearbeitungsmodus befindet und der Benutzer Berechtigungen für dieses Objekt PublishingPageEditListItem verfügen. Das Beispiel ECMAScript (JavaScript, JScript) für Postbacks an dieses Steuerelement verwendet, und wenn es ein postback-Ereignis auslöst, wird das Ereignis speichert das aktuelle PublishingPage -Objekt und zeigt die gespeicherte Seite in den Anzeigemodus.
