currently my countdown timer doesn't refresh itself every 1 second so it doesn't actually look like a timer. I'm trying fix this but I don't seem to know how. Here is my javascript code:

 //Event end date list data
let goodsList = [
  {actEndTime: '2023-1-22 10:00:43'},
]
Page({
  data: {
    countDownList: [],
    actEndTimeList: []
  },
  onl oad(){
    let endTimeList = [];
    //Commit the end time parameters of the event into a separate array for easy operation
    goodsList.forEach(o => {endTimeList.push(o.actEndTime)})
    this.setData({ actEndTimeList: endTimeList});
    //Execute countdown function
    this.countDown();
  },
  timeFormat(param){//Formatting function less than 10
    return param <10? '0'   param: param; 
  },
  countDown(){//Countdown function
    //Get the current time and the end time array of the event
    let newTime = new Date().getTime();
    let endTimeList = this.data.actEndTimeList;
    let countDownArr = [];

    //Process the end time and render it to the page
    endTimeList.forEach(o => {
      let endTime = new Date(o).getTime();
      let obj = null;
      //If the event is not over, process the time
      if (endTime-newTime> 0){
        let time = (endTime-newTime)/1000;
        //Get day, hour, minute, second
        let day = parseInt(time/(60 * 60 * 24));
        let hou = parseInt(time% (60 * 60 * 24)/3600);
        let min = parseInt(time% (60 * 60 * 24)% 3600/60);
        let sec = parseInt(time% (60 * 60 * 24)% 3600% 60);
        obj = {
          day: this.timeFormat(day),
          hou: this.timeFormat(hou),
          min: this.timeFormat(min),
          sec: this.timeFormat(sec)
        }
      }else{//The event has ended, all set to '00'
        obj = {
          day: '00',
          hou: '00',
          min: '00',
          sec: '00'
        }
      }
      countDownArr.push(obj);
    })
    //Render, and then execute a countdown function every second
    this.setData({ countDownList: countDownArr})
    setTimeout(this.countDown,1000);
  }
})

[[edited]] Here is when I restart compiling my project:

I'm creating this with miniprogram by the way, but using javascript.

CodePudding user response：

Instead of

setTimeout(this.countDown,1000);

use this

setInterval(this.countDown,1000);

try this pls...
