JavaScript 获取当前日期时间 年月日 时分秒的方法

// 格式化日对象
const getNowDate = () => {
  var date = new Date();
  var sign2 = ":";
  var year = date.getFullYear() // 年
  var month = date.getMonth() + 1; // 月
  var day = date.getDate(); // 日
  var hour = date.getHours(); // 时
  var minutes = date.getMinutes(); // 分
  var seconds = date.getSeconds() //秒
  var weekArr = ['星期一', '星期二', '星期三', '星期四', '星期五', '星期六', '星期天'];
  var week = weekArr[date.getDay()];
  // 给一位数的数据前面加 “0”
  if (month >= 1 && month <= 9) {
    month = "0" + month;
  }
  if (day >= 0 && day <= 9) {
    day = "0" + day;
  }
  if (hour >= 0 && hour <= 9) {
    hour = "0" + hour;
  }
  if (minutes >= 0 && minutes <= 9) {
    minutes = "0" + minutes;
  }
  if (seconds >= 0 && seconds <= 9) {
    seconds = "0" + seconds;
  }
  return year + "-" + month + "-" + day + " " + hour + sign2 + minutes + sign2 + seconds;
}
