Introduction
In this article, I explain how to show page load time using JavaScript.
Use the following procedure.
Step 1
Open Visual Studio 2012 and click "File" -> "New" -> "Web Site...". A window is opened. In this window, click "Empty Web Site" under Visual C#.

Give the name of your application as "Page_load_Time" and then click "Ok". Then add "HTML page" and write the following code.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title></title>
<script type="text/javascript">
var before_loadtime = new Date().getTime();
window.onload = Pageloadtime;
function Pageloadtime() {
var aftr_loadtime = new Date().getTime();
// Time calculating in seconds
pgloadtime = (aftr_loadtime - before_loadtime) / 1000
document.getElementById("loadtime").innerHTML = "Pgae load time is <font color='red'><b>" + pgloadtime + "</b></font> Seconds";
}
</script>
</head>
<body>
<h3 style="font-weight: bold; font-style: italic; font-size: large; color: #3333CC">Page load time in JavaScript</h3>
<div>
<span id="loadtime"></span>
</div>
</body>
