This is going to be difficult if not impossible. If your widget runs on a different domain than the embedding page, you will not be able to access the parent page's title property due to the Same Origin Policy.

If you're on the same domain you should be able to use window.parent.document.title. If you're not on the same domain but have control of the parent you could pass the title in via a query string argument.

If you're parent and child (the iframed) pages are on the same domain, you can use something like:

parent.document.getElementById('id_of_element').whatever();

to access the parent window's data.
