格式化日期时分秒

 

<script>
    var date = new Date();
    console.log(date.getHours()); //时
    console.log(date.getMinutes()); //分
    console.log(date.getSeconds()); //秒
    // 封装一个函数返回当前时分秒  格式  08:08:08
    function getTime() {
      var time = new Date();
      var h = time.getHours(); //时
      h = h < 10 ? "0" + h : h;
      var m = time.getMinutes(); //分
      m = m < 10 ? "0" + m : m;
      var s = time.getSeconds(); //秒
      s = s < 10 ? "0" + s : s;
      return h + ":" + m + ":" + s;
    }
    console.log(getTime());
  </script>
