<script language="JavaScript" type="text/javascript">

            function count_down()

            {

                

                var a=document.getElementById("<%=time1.ClientID%>").value;



                testDay=new Date(a);

                today=new Date();  //这里获得是本机的时间，如何获得服务器的？



                time=(testDay.getTime()-today.getTime())/(24*60*60*1000);

                if(time>0)

                {

                day=Math.floor(time);

                time=(time-day)*24;

                hour=Math.floor(time);

                time=(time-hour)*60;

                minute=Math.floor(time);

                time=(time-minute)*60;

                second=Math.floor(time);

                document.getElementById("<%=show_time.ClientID%>").innerHTML="距离本次团购结束还有</br><span style='color:red'>"+day+"</span>天<span style='color:red'>"+hour+"</span>小时<span style='color:red'>"+minute+"</span>分<span style='color:red'>"+second+"</span>秒";

                

                }

                else

                document.getElementById("<%=show_time.ClientID%>").innerHTML="团购已经结束";



            }

            window.setInterval("count_down()", 1000);
