JavaScript Popup\Dialog Box - Alert and Confirm Dialog Box
JavaScript provides the ability to pickup user input or small amount of text to user by using Popup box or Dialog Box.
Alert Dialog Box
The simplest way to direct small amounts of textual output to a browser's window is to use an alert box.
Syntax
alert("<message>");

<head>
<script type="text/javascript">
function popup() {
alert("Hello ! WELCOME TO MCN");
}
</script>
</head>
<body>
<input type="button" onclick="popup()" value="Click me" />
</body>
</html>
