Using Canvas Elements

So I was able to fully complete the stage for Donkey Kong, but alais as it is now 2 a.m. unfortunately I have merely ran out of steam to get the animation portion working. Neat thing is the elevator elements are not images, canvas is drawing those components. I need to brush up on loop scripting so I am not repeating simiar functions over and over again. And really need some help in getting the elements to move around.
