Get some element:
id='sub-div' => $('sub-div')
class='test' => $$('.test')[0]


get attribute => $('sub-div').readAttribute('attr')
set attribute => $('sub-div').setAttribute('attr', 'test')

Hi Zell,

Welcome!  Hope you find Prototype useful.

The best thing you can do when learning Prototype, in my view, is
spend an hour or two reading the API docs. [1]  Prototype's API isn't
so big that you can't read the entire thing all the way through, and
doing that will save you a LOT of time in the long run.

Hope this helps,
