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;"><img src="../images/dialog/4.gif" /> <imgsrc="../images/dialog/4.gif" /> <imgsrc="../images/dialog/4.gif" /> <imgsrc="../images/dialog/4.gif" /> <imgsrc="../images/dialog/4.gif" /> <imgsrc="../images/dialog/4.gif" /> <imgsrc="../images/dialog/4.gif" /> <imgsrc="../images/dialog/4.gif" /> </span><span id="marquePic2"style="width:600px;background-color:#990033;"></sp an> </div></div> <scripttype="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.scro llWidth){ imgmarquee.scrollLeft=0;}else{ //demo.scrollLeft+ +; imgmarquee.scrollLeft++; }} varmarqueetemp=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）－－－－－－－－－－－－向右－－－－－－－－－－－－<scriptlanguage="javascript"type="text/javascript"><!--var demo = document.getElementById("demo");var demo1 = document.getElementById("demo1");var demo2 = document.getElementById("demo2");var speed=10; //数值越大滚动速度越慢demo2.innerHTML =demo1.innerHTML;demo.scrollLeft =demo.scrollWidth;functionMarquee(){ if(demo.scrollLeft<=0)demo.scrollLeft+=demo2.offsetWidthelse{ demo.scrollLeft-- }}var MyMar = setInterval(Marquee,speed)demo.onmouseover = function(){clearInterval(MyMar)}demo.onmouseout = function(){MyMar =setInterval(Marquee,speed)}--></script>－－－－－－－－－－－－－向下－－－－－－－－－－－－－<scriptlanguage="javascript"type="text/javascript"><!--var demo = document.getElementById("demo");var demo1 = document.getElementById("demo1");var demo2 = document.getElementById("demo2");var speed=10; //数值越大滚动速度越慢demo2.innerHTML =demo1.innerHTML;demo.scrollTop =demo.scrollHeight;functionMarquee(){ if(demo1.offsetTop-demo.scrollTop>=0) demo.scrollTop+=demo2.offsetHeightelse{ demo.scrollTop-- }}var MyMar = setInterval(Marquee,speed);demo.onmouseover = function(){clearInterval(MyMar)}demo.onmouseout = function(){MyMar =setInterval(Marquee,speed)}--></script>－－－－－－－－－－－向上－－－－－－－－－－－<script language="javascript"type="text/javascript"><!--var demo = document.getElementById("demo");var demo1 = document.getElementById("demo1");var demo2 = document.getElementById("demo2");var speed=10; //滚动速度值，值越大速度越慢demo2.innerHTML =demo1.innerHTML //克隆demo2为demo1function Marquee(){ if(demo2.offsetTop-demo.scrollTop<=0) //当滚动至demo1与demo2交界时demo.scrollTop-=demo1.offsetHeight //demo跳到最顶端else{ demo.scrollTop++ }}var MyMar = setInterval(Marquee,speed); //设置定时器demo.onmouseover = function(){clearInterval(MyMar)}//鼠标经过时清除定时器达到滚动停止的目的demo.onmouseout = function(){MyMar =setInterval(Marquee,speed)} //鼠标移开时重设定时器--></script><DIV id=demo_1 style="OVERFLOW: hidden; HEIGHT: 136px"><DIV id=demo1_1><div id=gleft><a href=""><img src="" border="0" width=150 height="120"/></a></div><div id=gleft><a href=""><img src="" border="0" width=150 height="120"/></a></div><div id=gleft><a href=""><img src="" border="0" width=150 height="120"/></a></div><div id=gleft><a href=""><img src="" border="0" width=150 height="120"/></a></div></DIV><DIV id=demo2_1></DIV></DIV><SCRIPT>var speed=25demo2.innerHTML=demo1.innerHTMLfunction Marquee(){if(demo2.offsetWidth-demo.scrollLeft<=0)demo.scrollLeft-=demo1.offsetWidthelse{demo.scrollLeft++}}var MyMar=setInterval(Marquee,speed)demo.onmouseover=function() {clearInterval(MyMar)} demo.onmouseout=function(){MyMar=setInterval(Marquee,speed)} </SCRIPT> 其中<div id=gleft>这里的gleft的样式你自己定义下就OK 了。
