Realize the effect of e-commerce flash sale countdown in mini program

In e-commerce applications, flash sales are often used, and the flash sales will have a countdown function. Here we use the countdown function we showed you last time in e-commerce applications.


Basic implementation functions
1, the mini program imitates the e-commerce website flash kill countdown
2, the display format is: for example, 1 day 11 hours, 11 minutes, 11 seconds 11
3, flash kill After the time is up, it will prompt that the flash sale is over


Look at the renderings first

##In fact, the implementation is quite simple

<span style="font-size:18px;"><!--index.wxml--> 
<view class="container">  
<text >秒杀: {{clock}}</text>  
<text>{{micro_second}}</text>  
</view></span>

The following is the js implementation code

<span style="font-size:18px;">// indes.js  
/**   
 * 需要一个目标日期，初始化时，先得出到当前时间还有剩余多少秒  
 * 1.将秒数换成格式化输出为XX天XX小时XX分钟XX秒 XX  
 * 2.提供一个时钟，每10ms运行一次，渲染时钟，再总ms数自减10  
 * 3.剩余的秒次为零时，return，给出tips提示说，已经截止  
 */ 
    
// 定义一个总毫秒数，以一天为例  
// var total_micro_second = 3600 * 1000*24;//这是一天倒计时  
var total_micro_second = 10 * 1000;//这是10秒倒计时  
    
/* 毫秒级秒杀倒计时 */ 
function countdown(that) {  
   // 渲染倒计时时钟  
   that.setData({  
     clock:dateformat(total_micro_second)//格式化时间  
   });  
    
   if (total_micro_second <= 0) {  
     that.setData({  
       clock:"秒杀结束" 
     });  
     // timeout则跳出递归  
     return ;  
   }
