How to dynamically change a web page's title?

Question

I have a webpage that implements a set of tabs each showing different content. The tab clicks do not refresh the page but hide/unhide contents at the client side.

No

I just want to add something here: changing the title via JavaScript is actually useful if you're updating a database via AJAX, so then the title changes without you having to refresh the page. The title actually changes via your server side scripting language, but having it change via JavaScript is just a usability and UI thing that makes the user experience more enjoyable and fluid.

Now, if you're changing the title via JavaScript just for the hell of it, then you should not be doing that.
