//Our function to toggle classes without jQuery, it takes two parameters:
//1. The element to have a class toggled
//2. The name of the class we want to toggle
function toggleClass(el, _class) { //Check if the element exists, //& if it has the class we want to toggle if (el && el.className && el.className.indexOf(_class) >= 0) { //Element has the class, so lets remove it... //Find the class to be removed (including any white space around it) var pattern = new RegExp('\\s*' + _class + '\\s*'); //Replace that search with white space, therefore removing the class el.className = el.className.replace(pattern, ' '); } else if (el){ //Element doesn't have the class, so lets add it... el.className = el.className + ' ' + _class; } else { //Our element doesn't exist console.log("Element not found"); }
}
var square = document.getElementById("sqr"), body = document.body, text = document.getElementById("current-classes");
