Notify application icon using javascript

Question

Is there any way to make the application icon, in taskbar(windows) or dock(os x) to highlight, using javascript ?

When I say highlight, is like the jumping icon in os x.

What I need is when my web app receive a websocket message, the user knows that, even if he/she is using another application.

Answer 1

There is no way to do jumping icon animation analog via JavaScript. There is no such API. There are only 3 options:

1. Sound notification
2. HTML5 Notification API
3. Favicon update
