The permissionState()
method of the
PushManager
interface returns a Promise
that resolves to a
DOMString
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.
Syntax
PushManager.permissionState(options).then(function(PushMessagingState) { ... });
Parameters
options Optional
- An object containing optional configuration parameters. It can have the following
properties:
userVisibleOnly
: A boolean indicating that the returned push subscription will only be used for messages whose effect is made visible to the user.applicationServerKey
: A public key your push server will use to send messages to client apps via a push server. This value is part of a signing key pair generated by your application server and usable with elliptic curve digital signature (ECDSA) over the P-256 curve.
