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>

</dt>
<dd></dd>
</dl>
</div>
