我无法理解为什么我无法获得航点。代码在下面,我缺少什么(它必须是小而简单的东西)
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
<title></title>
<script src="http://imakewebthings.com/jquery-waypoints/waypoints.min.js"> </script>
<script>
$('#waypoint').waypoint(function () {
alert('You have scrolled to an entry.');
}, {
offset: '100%'
});
</script>
</head>
<body>
<div style="height: 1500px">Scroll down</div>
<div id="waypoint">Waypoint</div>
</body>
</html>

看起来你并没有包括jquery库,这是必需的。
<head>
<meta charset="utf-8" />
<title></title>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
