日期格式和千位符转换

最近在用的日期格式和千位符转换，简单的方法，拷贝即用！！！

  // 千位符转化
  formatMoney(s) {
    s = s.replace(/^(\d*)$/, "$1.");
    s = (s + "00").replace(/(\d*\.\d\d)\d*/, "$1");
    s = s.replace(".", ",");
    var re = /(\d)(\d{3},)/;
    while (re.test(s)) {
      s = s.replace(re, "$1,$2");
    }
    s = s.replace(/,(\d\d)$/, ".$1");
    return s;
  },
  // 时间格式转化(精确到秒)
  getYMDHMS(timestamp) {
    let time = new Date(timestamp);
    let year = time.getFullYear();
    let month = time.getMonth() + 1;
    let date = time.getDate();
    let hours = time.getHours();
    let minute = time.getMinutes();
    let second = time.getSeconds();

    if (month < 10) {
      month = "0" + month;
    }
    if (date < 10) {
      date = "0" + date;
    }
    if (hours < 10) {
      hours = "0" + hours;
    }
    if (minute < 10) {
      minute = "0" + minute;
    }
    if (second < 10) {
      second = "0" + second;
    }
    return (
      year +
      "-" +
      month +
      "-" +
      date +
      " " +
      hours +
      ":" +
      minute +
      ":" +
      second
    );
  }

如果大佬们有更好方法，欢迎交流哦，恭候！！！
