This article mainly introduces the WeChat applet dynamic display project countdown in detail. The format is such as 4 days, 7 hours, 58 minutes and 39 seconds. It has certain reference value. Interested friends can refer to it

The example in this article shares with you the specific code for dynamically displaying the countdown of the project in the WeChat applet for your reference. The specific content is as follows

1. Generally, when we talk about displaying flash sales, it refers to a single piece of data. I don’t have a loop. Do.

Effect:

2. wxml code:

<p>
<block wx:if="{{total_micro_second<=0}}">剩余时间:已经截止</block>
<block wx:if="{{clock!=&#39;已经截止&#39;}}">剩余时间:{{clock}}</block>
</p>

3. js file code:

function countdown(that) {
 var EndTime = that.data.end_time || [];
 var NowTime = new Date().getTime();
 var total_micro_second = EndTime - NowTime || [];
 console.log(&#39;剩余时间:&#39; + 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";
 }

Page({

 /**
 * 页面的初始数据
 */
 data: {
 id:&#39;&#39;,
 result:[],
 end_time:&#39;&#39;,
 clock:&#39;&#39;
 },/**
 * 生命周期函数--监听页面加载
 */
 onLoad: function (options) {
 var that = this;
 wx.request({
  url: &#39;https://m.******.com/index.php/Home/Xiaoxxf/activity_detail?a_id=&#39;+options.id,//不含富文本html
  data: {},
  method: &#39;GET&#39;, // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT
  header: {
  &#39;Content-Type&#39;: &#39;application/json&#39;
  },
  success: function (res) {
  that.setData({
   common: res.data, //一维数组,全部数据
   end_time: res.data.end_time //项目截止时间,时间戳,单位毫秒
  })
  console.log(that.data.common);
  console.log(&#39;结束时间:&#39; + that.data.end_time);
  },
  fail: function (res) { },
  complete: function (res) { },
 }), 
//调用上面定义的递归函数,一秒一刷新时间
 countdown(that);
},
