Instanz-Ereignisse​

Objekte welche mit new Notification erzeugt wurden emitieren folgende Events:

info

Some events are only available on specific operating systems and are labeled as such.

Event: 'show'​

Kehrt zurück:

  • event Event

Emitted when the notification is shown to the user. Note that this event can be fired multiple times as a notification can be shown multiple times through the show() method.

Ereignis: 'click'​

Kehrt zurück:

  • event Event

Emitted when the notification is clicked by the user.

Event: 'close'​

Kehrt zurück:

  • event Event

Emitted when the notification is closed by manual intervention from the user.

This event is not guaranteed to be emitted in all cases where the notification is closed.

On Windows, the close event can be emitted in one of three ways: programmatic dismissal with notification.close(), by the user closing the notification, or via system timeout. If a notification is in the Action Center after the initial close event is emitted, a call to notification.close() will remove the notification from the action center but the close event will not be emitted again.

Event: 'reply' macOS​

Kehrt zurück:

  • event Event
  • reply string - The string the user entered into the inline reply field.

Emitted when the user clicks the "Reply" button on a notification with hasReply: true.

Event: 'action' macOS​

Kehrt zurück:

  • event Event
  • index number - The index of the action that was activated.

Event: 'failed' Windows​

Kehrt zurück:

  • event Event
  • error string - The error encountered during execution of the show() method.

Emitted when an error is encountered while creating and showing the native notification.

Beispiel Methoden​

Objects created with the new Notification() constructor have the following instance methods:

notification.show()​

Immediately shows the notification to the user. Unlike the web notification API, instantiating a new Notification() does not immediately show it to the user. Instead, you need to call this method before the OS will display it.

If the notification has been shown before, this method will dismiss the previously shown notification and create a new one with identical properties.

notification.close()​

Schließt die Benachrichtigung.

On Windows, calling notification.close() while the notification is visible on screen will dismiss the notification and remove it from the Action Center. If notification.close() is called after the notification is no longer visible on screen, calling notification.close() will try remove it from the Action Center.

Instanz Eigenschaften​

Eine string Eigenschaft, die den Titel der Benachrichtigung darstellt.

notification.subtitle​
