js

<script>
    $(function(){

    })

    //订单滚动
    var Marquee = function(id){
      var container = document.getElementById(id), 
      original = container.getElementsByTagName("dt")[0], 
      clone = container.getElementsByTagName("dd")[0],
      liLength=original.getElementsByTagName("li").length,
      speed = 55;
      if(liLength<=8){
        return
      }
      clone.innerHTML = original.innerHTML;

      var rolling = function(){
        if (container.scrollTop === clone.offsetHeight) {
          container.scrollTop = 0;
        }
        else {
          container.scrollTop++;
        }
      }
      var timer = setInterval(rolling, speed)//设置定时器
      container.onmouseover = function(){
        clearInterval(timer)
      }//鼠标移到marquee上时，清除定时器，停止滚动
      container.onmouseout = function(){
        timer = setInterval(rolling, speed)
      }//鼠标移开时重设定时器
    }    
 </script>
