Answer 1

Try this :

window.onload = function(){
            var buttonGo = document.getElementsByTagName('button')[0];
            var buttonCom = document.getElementsByTagName('button')[1];
            var box = document.getElementById('box');
            buttonGo.onclick = function(){
                box.setAttribute('class','move');
            }
            buttonCom.onclick = function(){
               box.className=''
            }
       }

or double quotes box.className=""

Answer 2

box.removeAttribute("class") should work.
