Chrome extension development: auto close the notification box

Question

After doing something I run this code:

var notification = webkitNotifications.createNotification(
   \'icon.png\',  // icon url - can be relative
  \'Done!\'         


        

Answer 1

var notification = webkitNotifications.createNotification('images/icon-48x48.png',"This is       Title","Biswarup Adhikari Notification");
notification.show();
setTimeout(function(){
notification.cancel();
},2000);

Chrome notification will close automatically after 2000 milli sec or 2 sec.
