Javascript using getElementByClassName to change button colour

I am new to javascript and trying to write a javascript code so when a button is clicked its colour will change. I tried different ways but when clicked on the first element works. Not really sure what is going on here. I would appreciate any help.

var count = 1;          function setColor(button, color) {            var property = document.getElementsByClassName("button");            if (count == 0) {              property.style.backgroundColor = "#A94E3B"              count = 1;            }            else {              property.style.backgroundColor = "#EAE8E8"              count = 0;            }          }
