使用innerHTML 来实现图片的连续播放

 1 <script type=text/javascript> 
 2 var speed=30 
 3 marquePic2.innerHTML=marquePic1.innerHTML 
 4 function Marquee(){ 
 5 if(demo.scrollLeft>=marquePic1.scrollWidth){ 
 6 demo.scrollLeft=0 
 7 }
 8 else{ 
 9 demo.scrollLeft++ 
10 }} 
11 var MyMar=setInterval(Marquee,speed) 
12 demo.onmouseover=function() {clearInterval(MyMar)} 
13 demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)} 
14 </script>

 1 <div id=demo style="OVERFLOW: hidden; WIDTH: 760px; align: center">
