关于#vue.js#的问题：表格中的倒计时，如何结束时间endTime减去现在时间(语言-javascript)

表格中的倒计时，如何结束时间endTime减去现在时间，得出还剩几天几时几分钟几秒，超过就得出超时几天几时几分钟几秒

 
<template>
  <a-table :columns="columns" :data-source="dataSource">
    <template #bodyCell="{ column, text }">
      <template v-if="column.dataIndex === 'name'">
        <a>{{ text }}a>
      template>
      <template v-if="column.dataIndex === 'time'">
        <a>{{ text }}a>

import { defineComponent } from 'vue';
const dataSource = [
  {
    key: '1',

export default defineComponent({
  setup() {

      dataSource,

看之前的这个问题，改下getCountdownStr为下面即可

    const getCountdownStr = (time) => {
        time = new Date(time.replace(/-/g, '/'));
        let sec = Math.ceil((time.getTime() - currentTime.value.cur) / 1000);
        let prefix = sec >= 0 ? '还剩' :'超时'
        sec = Math.abs(sec);
        //if (sec <= 0) return '0天0时0分钟0秒';

        let day = Math.floor(sec / 24 / 3600);
        sec -= day * 24 * 3600;
        let hour = Math.floor(sec / 3600);
        sec -= hour * 3600;
        let minute = Math.floor(sec / 60);
        sec -= minute * 60;
        return `${prefix}${day}天${hour}时${minute}分${sec}秒`
    }
