js获取两个时间之间的所有日期、月份、年份

用JS实现获取2个时间点之间的日期、月份、年份（包括区间自身），代码如下：

1、获取日期

function getTimeTwo(start, end) {
  let diffdate = new Array();
  let arr = []
  let i = 0;
  while (start <= end) {
    diffdate[i] = start;
    let stime_ts = new Date(start).getTime();
    let next_date = stime_ts + (24 * 60 * 60 * 1000);
    let next_dates_y = new Date(next_date).getFullYear() + '-';
    let next_dates_m = (new Date(next_date).getMonth() + 1 < 10) ? '0' + (new Date(next_date).getMonth() + 1) + '-' : (new Date(next_date).getMonth() + 1) + '-';
    let next_dates_d = (new Date(next_date).getDate() < 10) ? '0' + new Date(next_date).getDate() : new Date(next_date).getDate();
    start = next_dates_y + next_dates_m + next_dates_d;
    i++;
  }
  return diffdate;
}
console.log(getTimeTwo('2022-01-12','2022-01-31'))

2、获取月份

function getMonthBetween(start, end) {
  let result = [];
  let min = new Date(start);
  let max = new Date(end);
  let curr = min;
  while (curr <= max) {
    let month = new Date(curr).getMonth() + 1;
    let t = ""
    if (month < 10) {
      t = '0' + month
    } else t = month
    let str = curr.getFullYear() + "-" + (t);
    let s = curr.getFullYear() + "-0";
    if (str == s) {
      str = curr.getFullYear() + "-12";
    }
    result.push(str);
    curr.setMonth(month);
  }
  return result;
}
console.log(getMonthBetween('2022-01','2023-12'))

3、获取年份

function getYearBetween(start, end){
  let result = [];
  let min = new Date(start).getFullYear();
  let max = new Date(end).getFullYear();
  while (min <= max) {
    result.push(min);
    min = (Number(min) + 1)
  }
  return result;
}
console.log(getYearBetween('2021-01-01','2022-01-01'))
