Permissions.revoke()

The Permissions.revoke() method of the Permissions interface reverts a currently set permission back to its default state, which is usually prompt.

Syntax

This method is called on the global Permissions object navigator.permissions.

var revokePromise = navigator.permissions.revoke(descriptor);

Parameters

descriptor

An object based on the PermissionDescriptor dictionary that sets options for the operation consisting of a comma-separated list of name-value pairs. The available options are:

• name: The name of the API whose permissions you want to query. Valid values are 'geolocation', 'midi', 'notifications', and 'push'.
• userVisibleOnly: (Push only, not supported in Firefox — see the Browser compatibility section below) Indicates whether you want to show a notification for every message or be able to send silent push notifications. The default is false.
• sysex: (MIDI only) Indicates whether you need and/or receive system exclusive messages. The default is false.

Returns

A Promise that calls its fulfillment handler with a PermissionStatus object indicating the result of the request.

Exceptions

TypeError

Retrieving the PermissionDescriptor information failed in some way, or the permission doesn't exist or is currently unsupported (e.g. midi, or push with userVisibleOnly).

Example

This function can be used by an app to request that its own Geolocation API permission be revoked.

function revokePermission() {
  navigator.permissions.revoke({name:'geolocation'}).then(function(result) {
    report(result.state);
  });
}
