微信小程序实现批量倒计时功能

<p class="promotion-label-tits">仅{{item.endtime}}</p>

//封装的倒计时方法//批量倒计时function grouponcountdown(that, end_time, param) { var EndTime = new Date(end_time).getTime(); // console.log(EndTime); var NowTime = new Date().getTime();  var total_micro_second = EndTime - NowTime;  var groupons = that.data.groupon; // console.log(groupons); groupons[param].endtime = dateformats(total_micro_second); if (total_micro_second <= 0) {  groupons[param].endtime = "已结束" } that.setData({  groupon: groupons }) setTimeout(function () {  grouponcountdown(that, end_time, param); }, 1000)} // 时间格式化输出，每1s都会调用一次function dateformats(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); var hrStr = hr.toString(); if (hrStr.length == 1) hrStr = '0' + hrStr;  // 分钟 var min = Math.floor(second / 60 % 60); var minStr = min.toString(); if (minStr.length == 1) minStr = '0' + minStr;  // 秒 var sec = Math.floor(second % 60); var secStr = sec.toString(); if (secStr.length == 1) secStr = '0' + secStr;  if (day <= 1) {  return "剩 " + hrStr + ":" + minStr + ":" + secStr; } else {  return "剩 " + day + " 天 " + hrStr + ":" + minStr + ":" + secStr; }}//end var app=getApp()Page({  /**  * 页面的初始数据  */ data: {   collageTeamlist : {} },  /**  * 生命周期函数--监听页面加载  */ onLoad: function (options) {   app.showLoading();   var that = this      wx.request({     success:function(res){       var grouponList = request.data.collageTeamlist       // console.log(grouponList);       for (var i = 0; i < grouponList.length; i++) {         var lack_num = grouponList[i].create_num - grouponList[i].current_num         grouponList[i].lack_num = lack_num       }        that.setData({         groupon: grouponList       })       var data = that.data.groupon       //列表获取到数据进行遍历       for (var i = 0; i < data.length; i++) {         var end_time = data[i].end_time.replace(/-/g, '/')         grouponcountdown(that,end_time, i)       }     },   }) },
