div实现向左右无缝滚动图片效果（跑马灯）

div实现向左右无缝滚动图片效果（跑马灯）
div+css学习笔记22（用div实现向左无缝滚动图片效果）JavaScript实现走马灯效果[无缝连接、循环滚动] 无缝跑马灯效果
以下代码在IE6、Firefox+Win2k环境下测试通过
网页走马灯连续循环滚动
废话少说，代码贴出来：
<div id="imgmarquee" style="OVERFLOW: hidden; WIDTH: 580px; align: left; background-color:#0099CC;">
<div style="width:1200px">
<!--id="marquePic1"里面的宽度一定要大于id="imgmarquee"的宽度才能看到效果width:600px;>WIDTH: 580px;
大的div宽度要为span的两倍才可以，不然会换行width:1200px zdz的作品，流风的作品 -->
<span id="marquePic1" style="width:600px; background-color:#990033;">

<span id="marquePic2" style="width:600px;background-color:#990033;"></span>
</div>
</div>
<script type="text/javascript">
var imgmarquee = document.getElementById('imgmarquee');
var marquePic2 = document.getElementById('marquePic2');
var marquePic1 = document.getElementById('marquePic1');
var speed=10;//控制移动的速度,数越大越慢
marquePic2.innerHTML=marquePic1.innerHTML;//把marquePic1的内容复制到marquePic2里面
function Marquee(){
if(imgmarquee.scrollLeft>=marquePic1.scrollWidth){
imgmarquee.scrollLeft=0;
}else{
//demo.scrollLeft++;
imgmarquee.scrollLeft++;
}
}
var marqueetemp=setInterval(Marquee,speed);
imgmarquee.onmouseover=function()
{clearInterval(marqueetemp)} //鼠标移到上面停止并清除计数
imgmarquee.onmouseout=function()
{marqueetemp=setInterval(Marquee,speed)} //鼠标离开重新计数
</script>

参考资料（向右，向上，向下代码同理，只是控制的js不同而已，把下面的id改成对应的就ok了）

其中<div id=gleft>这里的gleft的样式你自己定义下就OK了。
