Mouseover popup speech bubble

I'm new to javascript/css and would like to make a version of a mouseover popup similar to the one that displays over the underlined words here: http://st.japantimes.co.jp/essay/?p=ey20141219
I can see the code that is used, but I'm not sure where/how to add in my own speech bubble image when I edit the code for my own project.

Here is an example of the code used on the referenced page:


<a style="cursor:pointer;" onclick="showChuPopup(event,'<b>’Twas</b><br />It was の省略');return false;" onmouseover="showChuPopup(event,'<b>’Twas</b><br />It was の省略');" onmouseout="endChuPopup();">’Twas</a>


function showChuPopup(e,text){
if(document.all)e = event;

var obj = document.getElementById('chu_popup');
var obj2 = document.getElementById('chu_popup_text');
obj2.innerHTML = text;
obj.style.display = 'block';
var st = Math.max(document.body.scrollTop,document.documentElement.scrollTop);/*
var leftPos = e.clientX - 100;
if(leftPos<0)leftPos = 0;
obj.style.left = leftPos + 'px';
obj.style.top = e.clientY - obj.offsetHeight -1 + st + 'px';} function endChuPopup() {
document.getElementById('chu_popup').style.display = 'none';} function touchHandler(e){
document.getElementById('chu_popup').style.display = 'none';}

Thanks for any help or ideas.

There are a few ways to go about this, but I'll recommend two options and provide links to both!

First, check out the answer on this question to see if this is what you want:

jQuery Popup Bubble/Tooltip

Second, have you thought about just using a tooltip with CSS? They're not hard to implement at all, and you can absolutely bind data to them.

(Shamelessly stolen from: https://www.w3schools.com/css/css_tooltip.asp, I would recommend poking around here and also looking into Bootstrap if you're a beginner!)

.tooltip {
    position: relative;
    display: inline-block;
    border-bottom: 1px dotted black;

.tooltip .tooltiptext {
    visibility: hidden;
    width: 120px;
    background-color: black;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 5px 0;
    position: absolute;
    z-index: 1;
    top: 150%;
    left: 50%;
    margin-left: -60px;

.tooltip .tooltiptext::after {
    content: "";
    position: absolute;
    bottom: 100%;
    left: 50%;
    margin-left: -5px;
    border-width: 5px;
    border-style: solid;
    border-color: transparent transparent black transparent;

.tooltip:hover .tooltiptext {
    visibility: visible;

<div class="tooltip">Hover over me
  <span class="tooltiptext">Tooltip text</span>
