Example
Let us see an example for isSameNode() method −
<!DOCTYPE html>
<html>
<head>
<title>isSameNode()</title>
<style>
form {
width:70%;
margin: 0 auto;
text-align: center;
}
* {
padding: 2px;
margin:5px;
}
input[type="button"] {
border-radius: 10px;
}
ul{
width: 30%;
margin: 0 auto;
}
</style>
</head>
<body>
<form>
<fieldset>

</ul>
<input type="button" onclick="confirmTrophy()" value="Check">
<div id="divDisplay"></div>
</fieldset>
</form>
<script>
var divDisplay = document.getElementById("divDisplay");
var cricketTrophy = document.getElementById("cricket");
var trophyOne = document.getElementsByTagName("li")[0];
divDisplay.textContent = 'NOTE: Check if Trophy 1 was won in cricket';
function confirmTrophy() {
if(cricketTrophy.isSameNode(trophyOne))
divDisplay.textContent = 'Trophy 1 was indeed won in cricket';
else
divDisplay.textContent = 'Trophy 1 was not won in cricket';
}
