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) } }, }) },
