css中控制鼠标手型的属性(以及js控制)

<span style="cursor:pointer">手形span> 
<span style="cursor:crosshair">十字span> 
<span style="cursor:text" >文本光标span> 
<span style="cursor:wait" >等待span> 
<span style="cursor:default" >默认span> 
<span style="cursor:help" >问号span> 
<span style="cursor:e-resize" >左右箭头span> 
<span style="cursor:s-resize" >上下箭头span> 
<span style="cursor:auto" >系统自动给出效果span>
<span style="cursor: url(aaa.cur');">自定义图标span>
=======================分隔线=============================

js控制方式:
document.getElementsByTagName_r("span"[0].style.cursor="pointer" //手型

以此类推
