<!-- 方法1 -->
<script>
 const countdown = {
  domList : document.querySelectorAll('.jsTime'),
  formatNumber(n){
   // return n.toString().padStart(2, '0'); // 用padStart方法要注意兼容问题
   n = n.toString();
   return n[1] "htmlcode">

<!-- 方法2 -->
<script>
 //时间格式处理
 const formatNumber = n => {
 n = n.toString();
 return n[1] "nofollow" target="_blank" href="https://github.com/xiexikang/js-date-countdown" rel="external nofollow" target="_blank">github
