How to change window title from a frame in javascript?

Question

I hosted my web app on a freehoster service which shows my webpage in a frameset. 2 frames are there. In the top narrow frame there are their ad and the bottom frame is mine

Answer 1

use top.document.title (top refers to the top most window within the browser)

Answer 2

Yes, but it has to be on the same domain (and use a relative url for a path)

  window.parent.document.title = "Your new title";

If the iframe/frame is on a different domain, then you'll get a permission denied error.
