NotificationEvent: action property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Note: This feature is only available in Service Workers.
The action
read-only property of the NotificationEvent
interface returns the string ID of the notification button the user clicked. This value returns an empty string if the user clicked the notification somewhere other than an action button, or the notification does not have a button. The notification id is set during the creation of the Notification via the actions array attribute and can't be modified unless the notification is replaced.
Value
A string.
Examples
self.registration.showNotification("New articles available", {
actions: [{ action: "get", title: "Get now." }],
});
self.addEventListener(
"notificationclick",
(event) => {
event.notification.close();
if (event.action === "get") {
synchronizeReader();
} else {
clients.openWindow("/reader");
}
},
false,
);
