我写的代码，要下班了，所以就简单注释一下。鼠标经过会停止，移开鼠标会继续走。已经测试过了。另存xx.htm打开可看效果。
<script type="text/javascript">var timer_movex
start_timer()
function start_timer(){
timer_movex = setInterval(function() {//setInterval是js循环定时器每隔一段时间就执行一次function代码
var x = document.getElementById('x')//获得id为x的html元素
if(x.offsetLeft >= 800)
x.style.left = 0//如果移动到了800的位置，则跳回左边0点重新开始移动
else
x.style.left = x.offsetLeft + 50//向右移动20个像素
}, 1000)//每隔1000毫秒移动一次
}
function stop_timer() {
clearInterval(timer_movex)
}
function movex(v) {
var x = document.getElementById('x')//获得id为x的html元素
x.style.left = x.offsetLeft + v//移动v个像素，v为正数则向右，负数则向左。x.style.left即为左边框位置。
}
</script>
<div id="x" style="position:absolute left:500px top:100px width:100px height:100px border=1px solid #000" onmouseover="stop_timer()" onmouseout="start_timer()">
<h1>TEST</h1>
</div>
<form>
<input id="test" onclick="movex(-100)" value="点击左移" type="button"/>
<input id="test" onclick="movex(100)" value="点击右移" type="button"/>
<input id="test" onclick="start_timer()" value="start" type="button"/>
<input id="test" onclick="stop_timer()" value="stop" type="button"/>
</form>
我写一个你参考吧。<script language="javascript">var initTop = 0
function init(){
initTop = document.getElementById("advLayer").style.pixelTop
}
function move(){
document.getElementById("advLayer").style.pixelTop = initTop + document.body.scrollTop
}
window.onscroll = move// 窗体的滚动时间，当页面滚动时调用move()函数
</script><body onLoad="init()">
<img src="image/top.jpg"><img src= "image/content1.jpg"><img src="image/content2.jpg"><img src = "image/foot.jpg">
<div id = "advLayer" style="position:absoluteright:20pxtop:80pxz-index:10">
<A href="#"><img src="image/lady_0007.jpg" width="295" height="176" border="0"></A>
</div>
</body>希望能帮到您,谢谢。
