permissionState method

JSPromise<JSString> permissionState([
  1. PushSubscriptionOptionsInit options
])

The permissionState() method of the PushManager interface returns a Promise that resolves to a string indicating the permission state of the push manager. Possible values are 'prompt', 'denied', or 'granted'.

Note: As of Firefox 44, the permissions for Notifications and Push have been merged. If permission is granted for notifications, push will also be enabled.

Implementation

external JSPromise<JSString> permissionState(
    [PushSubscriptionOptionsInit options]);
