本文实例讲述了JS简单实现无缝滚动效果。分享给大家供大家参考，具体如下：

<!doctype html><title>javascript无缝滚动</title><meta charset="utf-8" /><meta name="keywords" content="javascript无缝滚动" /><meta name="description" content="javascript无缝滚动" /><style type="text/css">  h1 {    font: 400 16px/1 "Microsoft YaHei", KaiTi_GB2312, SimSun  }  #marquee {    position: relative;    width: 400px;    overflow: hidden;    border: 10px solid #8080C0;  }  #marquee img {    border: 0px;  }  #marquee dl,  #marquee dt,  #marquee dd,  #marquee a {    float: left;    margin: 0;    padding: 0;  }  #marquee dl {    width: 1000%;    height: 150px;  }</style><script type="text/javascript">var Marquee = function(id) {  try {    document.execCommand("BackgroundImageCache", false, true);  } catch(e) {};  var container = document.getElementById(id),    original = container.getElementsByTagName("dt")[0],    clone = container.getElementsByTagName("dd")[0],    speed = arguments[1] || 10;  clone.innerHTML = original.innerHTML;  container.scrollLeft = clone.offsetLeft  var rolling = function() {    if(container.scrollLeft == 0) {      container.scrollLeft = clone.offsetLeft;    } else {      container.scrollLeft--;    }  }  var timer = setInterval(rolling, speed) //设置定时器  container.onmouseover = function() {      clearInterval(timer)  } //鼠标移到marquee上时，清除定时器，停止滚动  container.onmouseout = function() {      timer = setInterval(rolling, speed)  } //鼠标移开时重设定时器}window.onload = function() {  Marquee("marquee");}</script><h1>javascript无缝滚动(向右滚动)</h1><div id="marquee">  <dl>    <dt>      <a href="###"><img src="img/o_s017.jpg" alt="javascript无缝滚动"/></a>      <a href="###"><img src="img/o_s018.jpg" alt="javascript无缝滚动"/></a>      <a href="###"><img src="img/o_s019.jpg" alt="javascript无缝滚动"/></a>      <a href="###"><img src="img/o_s020.jpg" alt="javascript无缝滚动"/></a>      <a href="###"><img src="img/o_s021.jpg" alt="javascript无缝滚动"/></a>      <a href="###"><img src="img/o_s022.jpg" alt="javascript无缝滚动"/></a>      <a href="###"><img src="img/o_s023.jpg" alt="javascript无缝滚动"/></a>    </dt>    <dd></dd>  </dl></div>

效果图如下：
