ServiceWorkerGlobalScope: notificationclose event
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is only available in Service Workers.
The notificationclose
event of the ServiceWorkerGlobalScope
interface fires when a user closes a displayed notification spawned by ServiceWorkerRegistration.showNotification()
.
Notifications created on the main thread or in workers which aren't service workers
using the Notification()
constructor will
instead receive a close
event on the Notification
object
itself.
This event is not cancelable and does not bubble.
