ServiceWorkerRegistration.getNotifications()
The getNotifications()
method of
the ServiceWorkerRegistration
interface returns a list of the
notifications in the order that they were created from the current origin via the
current service worker registration. Origins can have many active but
differently-scoped service worker registrations. Notifications created by one service
worker on the same origin will not be available to other active services workers on
that same origin.
Syntax
serviceWorkerRegistration.getNotifications(options)
.then(function(notificationsList) { ... });
Parameters
- options Optional
- An object containing options to filter the notifications returned. The available
options are:
tag
: ADOMString
representing a notification tag. If specified, only notifications that have this tag will be returned.
Return value
A Promise
that resolves to a list of Notification
objects.
Example
navigator.serviceWorker.register('sw.js');
var options = { tag : 'user_alerts' };
navigator.serviceWorker.ready.then(function(registration) {
registration.getNotifications(options).then(function(notifications) {
// do something with your notifications
})
});
