<title>增强版一页内上下左右滚动</title>
</head>
<body>
<p>注：上下滚动时，单元格demo1里面的内容高度要大于demo设置的高度才能无限滚动 </p>
<p>左右滚动时，单元格demo1里面的内容宽度要大于demo设置的宽度才能无限滚动 </p>
<p>一、上下滚动 </p>
<p>1.显示的内容 </p>
<p>2.向上滚动JS </p>
<div id="demot" style="overflow: hidden; widht: 200px; height: 60px; ">
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td id="demot1"><table width="100%" height="120" border="0" cellpadding="0" cellspacing="0">
<tr>
<td height="30">一</td>
</tr>

</div>
<script type="text/javascript">
function MarqueeToTop(){
var speed=30
var demo =document.getElementById("demot");
var demo1 =document.getElementById("demot1");
var demo2 =document.getElementById("demot2");
var MyMarTop=setInterval(MarqueeTop,speed)
demo2.innerHTML=demo1.innerHTML
//原理是不断的向demoh2中填入demoh1中的内容，然后将已经看不见的清除
//用一个两行一列的表格，上一列再放一个装填有内容的表格，定义为demoh1，下一列是空的TD，定义为demoh2
//SPEED是用来控制速度的。
demo.onmouseover=function(){ clearInterval(MyMarTop) }
demo.onmouseout=function(){ MyMarTop=setInterval(MarqueeTop,speed) }
function MarqueeTop(){
if(demo2.offsetHeight-demo.scrollTop<=0)
demo.scrollTop-=demo1.offsetHeight
else{
demo.scrollTop++
}
}
}
MarqueeToTop()
</SCRIPT>
<p>3.向下滚动JS </p>
<div id="demod" style="overflow: hidden; widht: 200px; height: 100px; ">
<table border="0" cellpadding="0" cellspacing="0">

demo2.innerHTML=demo1.innerHTML
demo.scrollTop=demo.scrollHeight
var MyMarDown=setInterval(MarqueeDown,speed)
demo.onmouseover=function() {clearInterval(MyMarDown)}
demo.onmouseout=function() {MyMarDown=setInterval(MarqueeDown,speed)}
function MarqueeDown(){
if(demo1.offsetTop-demo.scrollTop>=0)
demo.scrollTop+=demo2.offsetHeight
else{

}
}
}
MarqueeToDown()
</script>
<p>二、左右滚动 </p>
<p>1.显示内容 </p>
<p>2.向左滚动JS</p>
<div id="demol" style="overflow:hidden;height:100px;width:200px;">

<td>一</td>
<td>二</td>
<td>三</td>
</tr>
</table></td>
<td id="demol2"></td>
</tr>
</table>
</div>
<p>3.向右滚动JS</p>
<div id="demor" style="overflow:hidden;height:100px;width:200px;">
<table cellpadding="0" cellspace="0" border="0">
<tr>
<td id="demor1"><table width="200" border="0" cellspacing="0" cellpadding="0">
<tr>
<td>一</td>
<td>二</td>
<td>三</td>

<td id="demor2"></td>
</tr>
</table>
</div>
<script type="text/javascript">
function MarqueeToLeft(){
var speed=30
var demo =document.getElementById("demol");

function MarqueeLeft(){
if(demo2.offsetWidth-demo.scrollLeft<=0)
demo.scrollLeft-=demo1.offsetWidth
else{

MarqueeToLeft()
