How to make the code work?

Question

JavaScript

Code runs without error, scroll event is handled but no classes are added
javascript:
pastie.org/private/dqoktl6r3pbhb0w7hep5a
coffeescript:
pastie.org/private/w5fiqoaeeuzayiozhnc1lq

Answer 1

Most likely, the script is connected in the head and there the body does not exist yet, but try to do the initialization on the full page load event like this

$(function(){
    disableHover = new DisableHover($("body"));

    disableHover.scroll();
});
