Cannot Flash Window’s Title Bar Using JavaScript

Question:
How can I make the title bar of a window flash?

Answer:
This can’t be done using JavaScript. Most browsers delegate the responsibility for how their windows are displayed to their underlying operating systems. This means that from JavaScript you really don’t have any control over the window’s title bar. You can’t flash it, change its color, or make it do anything else even remotely interesting.
