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
