<h1>Amazing Web Page</h1>
<script type=”text/javascript”>
alert(‘But wait, there\’s more…’);
</script>
<p><a href=”JavaScript:self.close();”>Close This Page!</a></p>
</div>
</body>
</html>

<script type=”text/javascript”>
function alertUser(msg) {
alert(msg);
}
</script>
</head>
<body onload=”alertUser(‘Welcome to this AMAZING web page!’)”>
<div style=”text-align:center;padding:10px;”>
<h1>Amazing Web Page.</h1>
<p><a href=”JavaScript:self.close();”>Close</a></p>
</div>
</body>
</html>

function jumpto(x){

if (document.form1.jumpmenu.value != “null”) {
if (document.form1.jumpmenu.value != “http://www.quackit.com&#8221;) {
alert(‘Sorry to see you leaving Quackit. Hope to see you back soon!’);
}
document.location.href = x
}
