window.onload = function(){ var button = document.getElementById("button"); var rainbow = ["red", "orange","yellow","green","blue","indigo ", "violet"]; function change(){ document.body.style.background = rainbow[Math.floor(7*Math.random())]; } button.addEventListener("click", change); } math>Math body.background? what is it? I only know body.style.background "change()" seriously? It is "change" bc "click" event will do "change()" when click Absolutely I can explain more correctly and truly of that. But I'm afraid You will require more confuse

oh then Your code wrong again should be document.body.style.background =document.getElementById('thanks').innerHTML = rainbow[Math.floor(7*Math.random())]; document.getElementById('thanks') for select element with include id "thanks"

Because your script is executed before your html is loaded. So it cant find the button... I suggest you to put your whole script inside window.onload = function () { //your code }

Unfortunately that isn't working. It's popping a math error. Saying math is undefined.
