jQuery "height" method

In this tutorial ,we will discuss about "height" method of jQuery. The difference between .css('height') and .height() is that the latter returns a unit-less pixel value (for example, 400) while the former returns a value with units intact (for example, 400px). The .height() method is recommended when an element's height needs to be used in a mathematical calculation.


<!DOCTYPE html>
body { background:#4682B4; }
button { font-size:12px; margin:2px; }
p { width:150px; border:1px red solid; }
div { color:red; font-weight:bold; }
<script src="jquery-1.4.2.js"></script>
<button id="getp">Get Paragraph Height</button>
<button id="getd">Get Document Height</button>
<button id="getw">Get Window Height</button>

Sample paragraph to test height
function showHeight(ele, h) {
$("div").text("The height for the " + ele +
" is " + h + "px.");
$("#getp").click(function () {
showHeight("paragraph", $("p").height());
$("#getd").click(function () {
showHeight("document", $(document).height());
$("#getw").click(function () {
showHeight("window", $(window).height());
