Codeschool as courses on all of these, and they are very good.

Agreed. They are geared towards roughly novice level, and they have a Javascript track that will cover much of what OP wants at an acceptable intro level.

They are only good if you've never coded before.

If you have, they take at most a few hours to do and are largely a waste of money.

And as such they sound perfect for the poster of this Ask HN, as he stated he knows HTML/CSS and is a novice at Rails.

Thanks for your complete dismissal of my post because of your opinion on what works for you.
