This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
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.revoke()- Revokes the permission currently set on a given API.
Example
navigator.permissions.query({name:'geolocation'}).then(function(result) {
if (result.status == 'granted') {
showLocalNewsWithGeolocation();
} else if (result.status == 'prompt') {
showButtonToEnableLocalNews();
}
// Don't do anything if the permission was denied.
});
