Catch links in the element

Make all links inside the element with id="contents" ask the user if they really want to leave. And if they don't then don't follow.

Like this:

[iframe height=100 border=1 src="solution"]

Details:

HTML inside the element may be loaded or regenerated dynamically at any time, so we can't find all links and put handlers on them. Use event delegation.
The content may have nested tags. Inside links too, like <a href=".."><i>...</i></a>.
