在JavaScript中获取从星期一开始的按周编号的天数组

function getWeekDays() {
  var days = [];
  var currentDate = new Date();
  var currentDay = currentDate.getDay(); // 获取当前日期是星期几
  var currentMonthDay = currentDate.getDate(); // 获取当前日期是当月的第几天

  // 计算星期一对应的日期
  var mondayDate = new Date(currentDate);
  mondayDate.setDate(currentMonthDay - currentDay + 1);

  // 获取从星期一开始的按周编号的天数组
  for (var i = 0; i < 7; i++) {
    var day = new Date(mondayDate);
    day.setDate(mondayDate.getDate() + i);
    days.push(day);
  }

  return days;
}

var weekDays = getWeekDays();
console.log(weekDays);
