详解小程序毫秒级倒计时（适用于拼团秒杀功能）

废话不多说直接上代码：

效果图：

index.js

page({
 
 /**
  * 页面的初始数据
  */
 data: {
  countdown:''
,  enddate2: '2018-08-08 11:41:00'
 },
 /**
  * 生命周期函数--监听页面加载
  */
 onload: function (options) {
  var that = this;
  that.counttime()
 },
 counttime() {
  var that = this;
  var date = new date();
  var now = date.gettime();
  var enddate = new date(that.data.enddate2);//设置截止时间
  var end = enddate.gettime();
  var lefttime = end - now; //时间差               
  var d, h, m, s, ms;
  if (lefttime >= 0) {
   d = math.floor(lefttime / 1000 / 60 / 60 / 24);
   h = math.floor(lefttime / 1000 / 60 / 60 % 24);
   m = math.floor(lefttime / 1000 / 60 % 60);
   s = math.floor(lefttime / 1000 % 60);
   ms = math.floor(lefttime % 1000);
   ms = ms < 100 ? "0" + ms : ms
   s = s < 10 ? "0" + s : s
   m = m < 10 ? "0" + m : m
   h = h < 10 ? "0" + h : h
   that.setdata({
    countdown: d + "：" + h + "：" + m + "：" + s + ":" + ms,
   })
   //递归每秒调用counttime方法，显示动态时间效果
  settimeout(that.counttime, 100);
  } else {
   console.log('已截止')
   that.setdata({
    countdown:'00:00:00'
   })
  }
  
 },
})

index.html

<view>
  <text>{{countdown}}</text>
</view>
