notifications.getAll()

Gets all currently active notifications created by the extension.

This is an asynchronous function that returns a Promise.

None.

A Promise that will be fulfilled with an object. Each currently active notification is a property of this object: the name of the property is the ID of the notification, and the value of the property is a notifications.NotificationOptions object describing that notification.

Note that you can define an ID for a notification explicitly by passing it into notifications.create(). If you don't do this, the browser will generate one. Explicitly-specified IDs are strings, but generated IDs are numbers.

This example shows a notification when the user clicks a browser action, unless the notification was already being shown, in which case it clears the notification. It uses getAll() to figure out whether the notification is being shown:

let myNotification = "my-notification";

function toggleAlarm(all) {
  let ids = Object.keys(all);
  if (ids.indexOf(myNotification) != -1) {
    browser.notifications.clear(myNotification);
  } else {
    console.log("showing")

    browser.notifications.create(myNotification, {
      "type": "basic",
      "title": "Am imposing title",
      "message": "Some interesting content"
    });
  }
}

function handleClick() {
  console.log("clicked")
  browser.notifications.getAll().then(toggleAlarm);
}

browser.browserAction.onClicked.addListener(handleClick);

This example logs the title of all active notifications:

function logNotifications(all) {
  for (let id in all) {
    console.log(`Title: ${all[id].title}`);
  }
}

browser.notifications.getAll().then(logNotifications);
