<html>
<body>
<p>请把鼠标移动到单词上，可以看到鼠标指针发生变化：</p>
<span style="cursor:auto">
Auto</span><br />
<span style="cursor:crosshair">
Crosshair</span><br />
<span style="cursor:default">
Default</span><br />
<span style="cursor:pointer">

<span style="cursor:move">

<span style="cursor:e-resize">
e-resize</span><br />
<span style="cursor:ne-resize">
ne-resize</span><br />
<span style="cursor:nw-resize">
nw-resize</span><br />
<span style="cursor:n-resize">
n-resize</span><br />
<span style="cursor:se-resize">
se-resize</span><br />
<span style="cursor:sw-resize">
sw-resize</span><br />
<span style="cursor:s-resize">

<span style="cursor:w-resize">

<span style="cursor:text">

<span style="cursor:wait">

<span style="cursor:help">

</body>
</html>
通过HTML DOM course属性也可以实现这个效果：
语法：
Object.style.cursor=cursortype
实例
本例改变指针：
<html>
<head>
<script type="text/javascript">
function changeCursor()
{
document.body.style.cursor="crosshair";
document.getElementById("p1").style.cursor="text";
}
</script>
</head>
<body>
<p id="p1">This is some text. This is some text.
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
This is some text.</p>
<input type="button" onclick="changeCursor()"
value="Change cursor" />
</body>
</html>
