在你原来的代码上进行了修改，加粗倾斜的部分是添加或者修改的位置
<script>
var timer1 = null
var el = null
var left = 1
function moveItRight() {
if (parseInt(el.style.left) >(screen.width - 50)) //el.style.left = 0
{
left = -1
}
else if (parseInt(el.style.left) <= 0) {
left = 1
}
el.style.left = parseInt(el.style.left) + 2 * left + 'px'//本题目最关键的一句代码，让el对象的左边距每次循环都增加2像素，也就是向右移动了2像素
timer1 = setTimeout(moveItRight, 25)//隔25毫秒后运行一次moveItRight函数
}
window.onload = function () {
el = document.getElementById("div1")
el.style.left = '500px'
moveItRight()
}
</script>
用jquery写的，代码很简洁：<script src="jquery.js"></script>
<script>
function AutoScroll(obj){
$(obj).find("ul:first").animate({
marginTop:"-25px"
},500,function(){
$(this).css().find("li:first").appendTo(this)
})
}
$(document).ready(function(){
setInterval('AutoScroll("#scrollDiv")',2000)
)}
</script>
<div id="scrollDiv">
<ul>
<li>滚动内容</li>
</ul>
</div>
希望对你有所帮助
<script type="text/javascript">var speed=30
demo2.innerHTML=demo1.innerHTML
function Marquee(){
if(demo2.offsetWidth-demo.scrollLeft<=0)
demo.scrollLeft-=demo1.offsetWidth
else{
demo.scrollLeft++
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>
demo的css一定要设定width和overflow:hidden
<div id="demo">
<table border="0" cellspacing="0" cellpadding="0">
<tr>
<td>
<div id="demo1">
<table width="1000" height="172" border="0" cellpadding="0" cellspacing="0">
<tr>
<td>
文字放这里
</td>
</tr>
</table>
</div>
</td>
<td>
<div id="demo2"></div>
</td>
</tr>
</table>
</div>
原理demo2复制demo1然后连成一行，demo1滚动完滚动demo2因为内容一样所以看不出来，demo2滚动完滚动demo1
