微信小程序动态显示项目倒计时效果

<p>
<block wx:if="{{total_micro_second<=0}}">剩余时间已经截止</block>
<block wx:if="{{clock!='已经截止'}}">剩余时间{{clock}}</block>
</p>

function countdown(that) {
 var EndTime = that.data.end_time || [];
 var NowTime = new Date().getTime();
 var total_micro_second = EndTime - NowTime || [];
 console.log('剩余时间' + total_micro_second);
 // 渲染倒计时时钟
 that.setData({
 clock: dateformat(total_micro_second)
 });
 if (total_micro_second <= 0) {
 that.setData({
 clock: "已经截止"
 });
 //return;
 }
 setTimeout(function () {
 total_micro_second -= 1000;
 countdown(that);
 }
 , 1000)
 }

 // 时间格式化输出，如11:03 25:19 每1s都会调用一次
 function dateformat(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);
 // 分钟
 var min = Math.floor(second/60%60);
 // 秒
 var sec = Math.floor(second%60);
 return day + "天" + hr + "小时" + min + "分钟" + sec+"秒";
