直接用IE的 marquee 不行吗??
<marquee id=mm direction="right" scrolldelay="70" scrollamount="6">meizz</marquee><br>
<input type=button value=加速 onclick="add()">
<input type=button value=减速 onclick="sub()">
<input type=button value=right onclick="e.direction='right'">
<input type=button value=left onclick="e.direction='left'">
<input type=button value=up onclick="e.direction='up'">
<input type=button value=down onclick="e.direction='down'">
<script language="JavaScript"><!--
var e = document.getElementById("mm");
function add()
{
var n = 10;
if(e.scrollDelay-n > 0)
e.scrollDelay -= n;
e.scrollAmount += 1;
}
function sub()
{
if(e.scrollAmount > 0)
e.scrollAmount -= 1;
e.scrollDelay += 10;
}
//--></script>

我要的是点击按钮时滚动显示下四条记录。不按按妞的时候，四条记录是不会换的。
上滚已经实现，下滚老是搞不出。
请指点下，谢谢
