基本用法：
<frameset rows="20%,*">
<!--水平划分的第一个部分加载sample25_top.htm文件-->
<frame src="sample_top.htm" name="top">
<!--水平划分的第二个部分并没有加载文件，是再垂直划分为两个部分-->
<frameset cols="30%,*">
<!--垂直划分的第一个部分加载sample25_left.htm文件-->
<frame src="sample_left.htm" name="left">
<!--垂直划分的第二个部分加载sample01.htm文件-->
<frame src="index.htm" name="right">
</frameset>
</frameset>
示例：
<FRAMESET id="fsTop" border="0" frameSpacing="0" rows="106,*" topmargin="0" leftmargin="0" marginheight="0" marginwidth="0" cols="*">
<FRAME border="0" name="title" marginWidth="0" marginHeight="0" src="Top/Top.aspx" frameBorder="no" noResize scrolling="no" topmargin="0" leftmargin="0" borderColor="#e4e4e4">
