overflow:scroll; /*任何时候都强制显示滚动条*/
overflow:auto; /*需要的时候会出现滚动条*/
overflow-x:auto; /*控制X方向的滚动条*/
overflow-y:auto; /*控制Y方向的滚动条*/
示例:
<HTML>
<HEAD>
<TITLE>测试表格内的滚动条</TITLE>
</HEAD>
<BODY>
<table>
<tr>
<td>表格内的滚动条:</td>
<td>
<div id="wins"
style="position:absolute;height:200;width:200;overflow:auto;background:#EEEEEE;">
<p>pppppppppppppppppppppppppppppppppppppppppppppppppp </p>
<p>pppppppppppppppppppppppppppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
</div>
</td>
</tr>
<tr>
<td colspan="2" align="right">
<span onmouseover='scrollb=setInterval("wins.scrollLeft-=10",100)'

window.onscroll=function(){
var doc = document.documentElement || document.body;
if(doc .scrollTop > '你要求的高度'){
document.getElementById('xx').style.display='block';
}
}
