• All of its functions are cross-browser compatible.

faqs.js source code

"use strict";

var $ = function(id) { return document.getElementById(id); };

// the event handler for the click event of each a element

var toggle = function() {

var link = this; // the clicked a tag

var h2 = link.parentNode; // h2 tag that contains a tag

var div = h2.nextElementSibling; // h2 tag's sibling div tag

// toggle plus and minus image in h2 elements by adding or removing a class

if (h2.hasAttribute("class")) {

// h2.removeAttribute("class");

h2.className = "";

} else {

// h2.setAttribute("class", "minus");

h2.className = "minus";

}

// toggle div visibility by adding or removing a class

if (div.hasAttribute("class")) {

// div.removeAttribute("class");

div.className = "";

} else {

// div.setAttribute("class", "open");

div.className = "open";

}

};

window.onload = function() {

// get the a tags

var faqs = $("faqs");

var linkElements = faqs.getElementsByTagName("a");

// attach event handler for each a tag

for (var i = 0; i

linkElements[i].onclick = toggle;

}

// set focus on first tag

linkElements[0].focus();

};
