js

<script>
    $(function(){
        marquee("marquee");
    })

    //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>
