Well, I just gave you the basics, you didn't say how well you knew JS. So I'll assume you are a beginner - here is a full working version:

HTML Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

	<head>
		<meta http-equiv="content-type" content="text/html;charset=iso-8859-1">
		<title>Untitled Page</title>
		<script type="text/javascript"><!--
function generateRandom() {
	rNum = Math.ceil(Math.random() * 3000);
	document.form1.randNum.value = rNum;
}
//-->
</script>
	</head>

	<body bgcolor="#ffffff">
	<form name="form1">
		<input name="randNum" type="text">
		<input type="button" value="Generate" onclick="generateRandom();">
	</form>
</body>

</html>
