<iframe name="leftframe" marginwidth=1 marginheight=1 src="leftmenu.asp" frameborder=no width="100%" scrolling="no" height=100%></iframe>
让竖条没有:
<body style='overflow:scroll;overflow-y:hidden'>
</body>
让横条没有:
<body style='overflow:scroll;overflow-x:hidden'>
</body>
两个都去掉？更简单了
<body scroll="no">
</body>
