// Note: There's no need to call webkitNotifications.checkPermission().
// Extensions that declare the notifications permission are always
// allowed create notifications.

// Create a simple text notification:
var notification = webkitNotifications.createNotification(
  '48.png',  // icon url - can be relative
  'Hello!',  // notification title
  'Lorem ipsum...'  // notification body text
);

// Or create an HTML notification:
var notification = webkitNotifications.createHTMLNotification(
  'notification.html'  // html url - can be relative
);

// Then show the notification.
notification.show();
