The Notification
interface of the Notifications API is used to configure and display desktop notifications to the user. These notifications' appearance and specific functionality vary across platforms but generally they provide a way to asynchronously provide information to the user.
Constructor
Notification()
- Creates a new instance of the
Notification
object.
Properties
Static properties
These properties are available only on the Notification
object itself.
Notification.permission
Read only- A string representing the current permission to display notifications. Possible values are:
denied
— The user refuses to have notifications displayed.granted
— The user accepts having notifications displayed.default
— The user choice is unknown and therefore the browser will act as if the value were denied.
Instance properties
These properties are available only on instances of the Notification
object.
Notification.actions
Read only- The actions array of the notification as specified in the constructor's
options
parameter. Notification.badge
Read only- The URL of the image used to represent the notification when there is not enough space to display the notification itself.
Notification.body
Read only- The body string of the notification as specified in the constructor's
options
parameter. Notification.data
Read only- Returns a structured clone of the notification’s data.
Notification.dir
Read only- The text direction of the notification as specified in the constructor's
options
parameter. Notification.lang
Read only- The language code of the notification as specified in the constructor's
options
parameter. Notification.tag
Read only- The ID of the notification (if any) as specified in the constructor's
options
parameter. Notification.icon
Read only- The URL of the image used as an icon of the notification as specified in the constructor's
options
parameter. Notification.image
Read only- The URL of an image to be displayed as part of the notification, as specified in the constructor's
options
parameter. Notification.renotify
Read only- Specifies whether the user should be notified after a new notification replaces an old one.
Notification.requireInteraction
Read only- A
Boolean
indicating that a notification should remain active until the user clicks or dismisses it, rather than closing automatically. Notification.silent
Read only- Specifies whether the notification should be silent — i.e., no sounds or vibrations should be issued, regardless of the device settings.
Notification.timestamp
Read only- Specifies the time at which a notification is created or applicable (past, present, or future).
Notification.title
Read only- The title of the notification as specified in the first parameter of the constructor.
Notification.vibrate
Read only- Specifies a vibration pattern for devices with vibration hardware to emit.
Event handlers
Notification.onclick
- A handler for the
click
event. It is triggered each time the user clicks on the notification.
Notification.onclose
- A handler for the
close
event. It is triggered when the user closes the notification.
Notification.onerror
- A handler for the
error
event. It is triggered each time the notification encounters an error. Notification.onshow
- A handler for the
show
event. It is triggered when the notification is displayed.
Methods
Static methods
These methods are available only on the Notification
object itself.
Notification.requestPermission()
- Requests permission from the user to display notifications.
Instance methods
These properties are available only on an instance of the Notification
object or through its prototype
. The Notification
object also inherits from the EventTarget
interface.
Notification.close()
- Programmatically closes a notification.
Example
Assume this basic HTML:
<button onclick="notifyMe()">Notify me!</button>
It's possible to send a notification as follows — here we present a fairly verbose and complete set of code you could use if you wanted to first check whether notifications are supported, then check if permission has been granted for the current origin to send notifications, then request permission if required, before then sending a notification.
function notifyMe() { // Let's check if the browser supports notifications if (!("Notification" in window)) { alert("This browser does not support desktop notification"); } // Let's check whether notification permissions have already been granted else if (Notification.permission === "granted") { // If it's okay let's create a notification var notification = new Notification("Hi there!"); } // Otherwise, we need to ask the user for permission else if (Notification.permission !== "denied") { Notification.requestPermission().then(function (permission) { // If the user accepts, let's create a notification if (permission === "granted") { var notification = new Notification("Hi there!"); } }); } // At last, if the user has denied notifications, and you // want to be respectful there is no need to bother them any more. }
Alternate example: run on page load
In many cases, you don't need to be this verbose. For example, in our Emogotchi demo (see source code), we simply run Notification.requestPermission
regardless to make sure we can get permission to send notifications (this uses the newer promise-based method syntax):
Notification.requestPermission().then(function(result) { console.log(result); });
Then we run a simple spawnNotification()
function when we want to fire a notification — this is passed arguments to specify the body, icon, and title we want. Then it creates the necessary options
object and fires the notification using the Notification()
constructor.
function spawnNotification(body, icon, title) { var options = { body: body, icon: icon }; var n = new Notification(title, options); }
