Gets all currently active notifications created by the extension.
This is an asynchronous function that returns a
Promise
.
var gettingAll = browser.notifications.getAll()
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.
BCD tables only load in the browser
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:
var 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);
