The Permissions interface of the Permissions API provides the core Permission API functionality, such as methods for querying and revoking permissions

Methods

Permissions.query(): Returns the user permission status for a given API.
Permissions.request(): Requests permission to use a given API. This is not currently supported in any browser.
Permissions.requestAll(): Requests permission to use a given set of APIs. This is not currently supported in any browser.
Permissions.revoke(): Revokes the permission currently set on a given API.

Example

navigator.permissions.query({name:'geolocation'}).then(function(result) {
  if (result.state === 'granted') {
    showLocalNewsWithGeolocation();
  } else if (result.state === 'prompt') {
    showButtonToEnableLocalNews();
  }
  // Don't do anything if the permission was denied.
});
