2. wxml code:

3. js file code:

function countdown(that) {
 var EndTime = that.data.end_time || [];
 var NowTime = new Date().getTime();
 var total_micro_second = EndTime - NowTime || [];
 console.log(&#39;剩余时间：&#39; + total_micro_second);
  // 渲染倒计时时钟
  that.setData({
  clock: dateformat(total_micro_second)
  });
  if (total_micro_second <= 0) {
  that.setData({
   clock: "已经截止"
  });
  //return;
  }
  setTimeout(function () {
  total_micro_second -= 1000;
  countdown(that);
  }
  , 1000)
 }

 // 时间格式化输出，如11:03 25:19 每1s都会调用一次
 function dateformat(micro_second) {
  // 总秒数
  var second = Math.floor(micro_second / 1000);
  // 天数
  var day = Math.floor(second/3600/24);
  // 小时
  var hr = Math.floor(second/3600%24);
  // 分钟
  var min = Math.floor(second/60%60);
  // 秒
  var sec = Math.floor(second%60);
  return day + "天" + hr + "小时" + min + "分钟" + sec+"秒";
 }

  },
  fail: function (res) { },
  complete: function (res) { },
 }), 
//调用上面定义的递归函数，一秒一刷新时间
