Using JavaScript you can create three kinds of pop-up boxes, Alert box, Confirm box and prompt box.
Alert Box
An alert box is used if you want to make sure information comes through to the user. When an alert box pops up, the user will have to click on "OK" to processed.
Syntax:
alert("Alert Text")
Example:
<html>
<head>
<script type="text/javascript">
function display_alert()
{
alert("This is an alert box!")
}
</script>
</head>
<body>
<input type="button" onclick="display_alert()" value="Display alert box"/>
</body>
</html>
