React的倒计时组件

1. npm：https://www.npmjs.com/package/react-time-countdown
2. demo：https://realgeoffrey.github.io/react-time-countdown/demo/index.html

安装-引用

1. Node.js

   npm install react-time-countdown --save

   import TimeCountdown from 'react-time-countdown'

2. 浏览器

   <!-- 需要先引入react技术栈：
       <script src='//unpkg.com/react@18/umd/react.production.min.js'></script>
       <script src='//unpkg.com/react-dom@18/umd/react-dom.production.min.js'></script>
   
       <script src='//unpkg.com/babel-standalone@6/babel.min.js'></script>
   -->
   <script src="//unpkg.com/react-time-countdown"></script>
   
   <script>
   const TimeCountdown = window['react-time-countdown'].default
   </script>

用法

<TimeCountdown
  deadlineTimestamp={结束时间戳（必填）}
  callback={() => {
    // 倒计时结束时执行的回调函数
  }}
  leftMillisecond={提前到期的毫秒数（0）}
  renderMillisecond={(millisecond: number): React.ReactNode => {
    // 参数：倒计时还剩下多少毫秒
    // 返回：渲染本组件
  }}
  intervalDelay={每次调用渲染的间隔时间，毫秒（1000）}
/>
