分享实现滚动的问题？
<SCRIPT language="javascript">说明的是mmh为一个div标签，里面包含mmh1,mmh2,mmh1中有要滚动显示的内容，mmh2为空div标签
var speed=20;
mmh2.innerHTML=mmh1.innerHTML;这句能看懂，将mmh1中的内容付给mmh2
function Marquee(){
if(mmh2.offsetHeight-mmh.scrollTop<=0){什么意思offsetheight和scrolltop，相减的意思是什么？
mmh.scrollTop-=mmh1.offsetHeight; }说说大概意思
else{ mmh.scrollTop++; }说说大概意思
}，下面的我知道意思
var Mymmh=setInterval(Marquee,speed);
//alert(Mymmh);
mmh.onmouseover=function()
{clearInterval(Mymmh);}
mmh.onmouseout=function()
{Mymmh=setInterval(Marquee,speed);}
</SCRIPT>谢谢达人

html语言里面有滚动的方式，你到底想要的是什么样的效果？难道说那个
<marquee direction="left" scrollamount="3" width="98%" onMouseOut="this.start()" onMouseOver="this.stop()">滚动内容</marquee>
如果上面的这段代码实现不了你的要求，可以按照以下的代码进行改造，达到你所需要的效果。
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
<style type="text/css">
<!--
td {font-size: 12px; font-family: Arial,Verdana,sans-serif;}
}
-->
</style>
</head>
<body>
<div id="icefable1">
<table border="0" cellpadding="0" cellspacing="0" id="box16left">
<tr>
<td1111111111111111111</td>

<tr>
<td>ffffffffffffffffffffff</td>

</div>

这个实现的是关于文本的滚动，我没有看明白你的那个要求，真的对不起了……不过感觉改造下这个代码，一定能够实现你的要求的说

谢谢你，我在毕业设计，只是想明白我的代码的意思。还是要再次感谢你！
