纯手敲 觉得有用可以点个赞啊
<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
可以实现匀速、无缝、加链接以及其它的修饰效果，本代码就是实现了这一功能，让文字从右至右平滑滚动，滚动宽度、高度、速度均可以设定。Js文字向左运动

marqueewidth=350

全选
注:如需引入外部Js需刷新才能执行]
