使网页中的图片无空隙上、下、左、右、滚动的JS代码〈绝对可用〉

向上滚动的代码：

<div id=demo style=overflow:hidden;height:100;90;
background:#214984;color:#ffffff>
<div id=demo1>
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
</div>
<div id=demo2></div>
</div>
<script>
var speed=30
demo2.innerHTML=demo1.innerHTML //克隆demo1为demo2
function Marquee(){
//当滚动至demo1与demo2交界时
if(demo2.offsetTop-demo.scrollTop<=0)
demo.scrollTop-=demo1.offsetHeight //demo跳到最顶端
else{
demo.scrollTop++
}
}
var MyMar=setInterval(Marquee,speed)//设置定时器
//鼠标移上时清除定时器达到滚动停止的目的
demo.onmouseover=function() {clearInterval(MyMar)}
//鼠标移开时重设定时器
demo.onmouseout=function(){MyMar=setInterval(Marquee,speed)}
</script>

向下滚动的代码：

<div id=demo style=overflow:hidden;height:100;90;
background:#214984;color:#ffffff>
<div id=demo1>
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
<img src="http://www.baidu.com/img/logo.gif">
</div>
<div id=demo2></div>
</div>
<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
demo.scrollTop=demo.scrollHeight
function Marquee(){
if(demo1.offsetTop-demo.scrollTop>=0)
demo.scrollTop+=demo2.offsetHeight
else{
demo.scrollTop--
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>

向左滚动的代码：

<div id="demo" style="overflow:hidden;670px;color:#ffffff;">
<table cellpadding="0" cellspacing="0" border="0">
<tr><td id="demo1" valign="top" align="center">
<table cellpadding="2" cellspacing="0" border="0">
<tr align="center">
<td><img src="http://www.baidu.com/img/logo.gif"></td>
<td><img src="http://www.baidu.com/img/logo.gif"></td>
<td><img src="http://www.baidu.com/img/logo.gif"></td>
<td><img src="http://www.baidu.com/img/logo.gif"></td>
<td><img src="http://www.baidu.com/img/logo.gif"></td>
</tr>
</table>
</td>
<td id="demo2" valign="top"></td>
</tr>
</table>
</div>
<script>
var speed=1//速度数值越大速度越慢
demo2.innerHTML=demo1.innerHTML
function Marquee(){
if(demo2.offsetWidth-demo.scrollLeft<=0)
demo.scrollLeft-=demo1.offsetWidth;
else{
demo.scrollLeft++;
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>

向右滚动的代码：

<div id="demo" style="overflow:hidden;670px;color:#ffffff;">
<table cellpadding="0" cellspacing="0" border="0">
<tr><td id="demo1" valign="top" align="center">
<table cellpadding="2" cellspacing="0" border="0">
<tr align="center">
<td><img src="http://www.baidu.com/img/logo.gif" ></td>

<td><img src="http://www.baidu.com/img/logo.gif" ></td>
<td><img src="http://www.baidu.com/img/logo.gif" ></td>
<td><img src="http://www.baidu.com/img/logo.gif" ></td>
</tr>
</table>
</td>
<td id="demo2" valign="top"></td>
</tr>
</table>
</div>
<script>
var speed=1//速度数值越大速度越慢
demo2.innerHTML=demo1.innerHTML
function Marquee(){
if(demo.scrollLeft<=0)
demo.scrollLeft+=demo2.offsetWidth
else{
demo.scrollLeft--
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
