网上下了一个ASP.NET的实例，打算自己研究研究的，可是运行的时候出现了错误，具体代码如下：

<div id="topmenu">

        <ul>

                 <li id="one"><a href="Default.aspx" onmouseout="MM_showHideLayers('sub02','','hide')"

                onmouseover="MM_showHideLayers('sub02','','show')" title="新闻资讯">首页</a></li>

找到原因了，缺少定义。看来先要去补补基础
function MM_showHideLayers() { //v9.0
var i,p,v,obj,args=MM_showHideLayers.arguments;
for (i=0; i<(args.length-2); i+=3)
with (document) if (getElementById && ((obj=getElementById(args[i]))!=null)) { v=args[i+2];
if (obj.style) { obj=obj.style; v=(v=='show')?'visible':(v=='hide')?'hidden':v; }
obj.visibility=v; }
}
