Question

一个网页如何插入两个同样效果的js 插入后两段都不显示了，下面是代码，可以顺便帮我改一下吗？

<DIV id=demo style="OVERFLOW: hidden; WIDTH: 762px; HEIGHT: 165px">
<table cellPadding=0 align=center border=0 cellspace="0">
<tr>
<td id=demo1 vAlign=top><%=TopProducts()%> </td>
<td id=demo2 vAlign=top></td>
</tr>
</table>
<SCRIPT>
var speed=20
demo2.innerHTML=demo1.innerHTML
function Marquee1(){
if(demo2.offsetWidth-demo.scrollLeft<=0)
demo.scrollLeft-=demo1.offsetWidth
else{
demo.scrollLeft++
} }
var MyMar1=setInterval(Marquee1,speed)
demo.onmouseover=function() {clearInterval(MyMar1)}
demo.onmouseout=function() {MyMar1=setInterval(Marquee1,speed)}
</SCRIPT>
</div>

Answer 1

调用
scrollfn(document.getElementById("demo2"),document.getElementById("demo1"))
scrollfn(document.getElementById("xx2"),document.getElementById("xx1"))
封成方法
function scrollfn(demo2,demo1){
var speed=20
demo2.innerHTML=demo1.innerHTML
function Marquee1(){
if(demo2.offsetWidth-demo.scrollLeft<=0)
demo.scrollLeft-=demo1.offsetWidth
else{
demo.scrollLeft++
} }
var MyMar1=setInterval(Marquee1,speed)
demo.onmouseover=function() {clearInterval(MyMar1)}
demo.onmouseout=function() {MyMar1=setInterval(Marquee1,speed)}
}

有冲突，你把其中一个的变量名换了就好了。
