Hi.. I have: <td id="hours" <%= too_many?(@project.planned_hours, @all_hours) %>>..... This returnes a class to alter the background-color, but only on reload. As the page is not submitted(ajax) on entry new values, I want to change this helper to a js/coffee function so if val 2 > val 1 the background color changes. How to approch that?
