怎样让鼠标光标变成放大/缩小的形状?

<body>000</body>
<script language="javascript">
<!--
document.body.style.cursor = "e-resize";
//-->
</script>
----------------------------------
其中"e-resize"可变化如下： 
e-resize：鼠标指针向右 
s-resize: 鼠标指针向下 
w-resize: 鼠标指针向左 
n-resize: 鼠标指针向上 
ne-resize: 鼠标指针向东北 
se-resize: 鼠标指针向东南 
sw-resize: 鼠标指针向西南 
nw-resize: 鼠标指针向西北 
crosshair: 十字 
move: 移动状
