<!--滚动的javascript-->
<script>
var t=demo.scrollWidth
demo1.innerHTML+=demo1.innerHTML
function doMarquee()
{
demo.scrollLeft=demo.scrollLeft<demo.scrollWidth-demo.offsetWidth?demo.scrollLeft+3:t-demo.offsetWidth
}
function doscroll()
{
   sc=setInterval(doMarquee,20)
}
function stopscroll()
{
   clearInterval(sc)
}
doscroll()
</script>
</div>
  </div>
  <div class="buttom"></div>
</div>
提示onMouseOver="stopscroll();"
onmouseout="doscroll()"标签DIV属性不被支持，运行后火狐不兼容
