Actually that's not the best example. There is some "standardisation" that goes on for the href attribute. Especially with respect to IE and how it deals with adding or leaving off the full path.
Oops sorry, that's true. That was just the first example that popped into my head.
If you were looping over form inputs, you could do this.name or this.id instead of $(this).attr("name") or $(this).attr("id") - that's probably a better example.
