notifications.getAll()

Gets all currently active notifications created by the extension.

This is an asynchronous function that returns a Promise.

Syntax

js

let gettingAll = browser.notifications.getAll()

Parameters

None.

Return value

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.

Browser compatibility

BCD tables only load in the browser

Examples

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:

js

const myNotification = "my-notification";

function toggleAlarm(all) {
  const ids = Object.keys(all);
  if (ids.includes(myNotification)) {
    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:

js

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

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