notifications.onClicked

browser.notifications.onClicked.addListener(callback)
browser.notifications.onClicked.removeListener(listener)
browser.notifications.onClicked.hasListener(listener)

Events have three functions:

addListener(callback)

Adds a listener to this event.

removeListener(listener)

Stop listening to this event. The listener argument is the listener to remove.

hasListener(listener)

Check whether listener is registered for this event. Returns true if it is listening, false otherwise.

callback

Function that will be called when this event occurs. The function will be passed the following arguments:

notificationId

string. ID of the notification that the user clicked.

In this simple example we add a listener to the notifications.onClicked event to listen for system notifications being clicked. When this occurs, we log an appropriate message to the console.

browser.notifications.onClicked.addListener((notificationId) => {
  console.log(`Notification ${notificationId} was clicked by the user`);
});
