 <title>团购——限时抢</title>
</head>
<body>
<div>
 <div class="time">还剩 <span id="LeftTime"></span></div>
</div>
<script>
 function FreshTime() {
  var endtime = new Date("2017/10/15,12:20:12");//结束时间
  var nowtime = new Date();//当前时间
  var lefttime = parseInt((endtime.getTime() - nowtime.getTime()) / 1000);
  d = parseInt(lefttime / (24 * 3600));
  h = parseInt(lefttime /3600%24);
  m = parseInt(lefttime/60%60);
  s = parseInt(lefttime % 60);

  document.getElementById("LeftTime").innerHTML = d + "天" + h + "小时" + m + "分" + s + "秒";
  if (lefttime <= 0) {
   document.getElementById("LeftTime").innerHTML = "团购已结束";
   clearInterval(sh);
  }
 }

 var sh;
 sh = setInterval(function () {
  FreshTime()
 },500);

</script>

</body>
</html>
