Tutorials using JS

Problem Statement

get the height of a div element using JavaScript

Solution

to get the height of a div element using JavaScript, we can read either of the three following properties based on the inclusion of padding, borders, or scrolling height

divElement.clientHeight //height + vertical padding
divElement.offsetHeight //height + vertical padding + vertical borders
divElement.scrollHeight //height of contained doc + vertical padding

Program

when user clicks on the Click me button, we get the div element with the id myDiv, and then display the clientHeight, offsetHeight, and scrollHeight of the div in console

<!DOCTYPE html>
<html>
<body>
<h1>JavaScript Tutorial</h1>
<button id="myBtn">Click me</button>
<div id="myDiv" class="card tile active">About</div>
<p id="output"></p>

<style>
#myDiv {
	margin: 10px;
	padding : 5px;
	width: 100px;
	height: 100px;
}
</style>

<script>
document.getElementById("myBtn").addEventListener("click", function() {
	//get div element
	const myDiv = document.getElementById("myDiv");
	//display different heights of div
	document.getElementById("output").innerHTML += myDiv.clientHeight + '<br>';
	document.getElementById("output").innerHTML += myDiv.offsetHeight + '<br>';
	document.getElementById("output").innerHTML += myDiv.scrollHeight;
});
</script>

</body>
</html>
