微信小程序实现批量倒计时功能

本文实例为大家分享了微信小程序实现批量倒计时的具体代码，供大家参考，具体内容如下

//适用于商品列表倒计时/** * end_time int 结束时间 * param int 数组键 */

1.展示效果如下：

2.wxml代码：

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

3.js代码： 

//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)
       }
     },
   })
 },
