这个比较准确经过测试    原文忘记在哪了   有知道的老铁可以在底下评论

getMonthBetween(start, end) {
          var result = {};
          var s = start.split('-');
          var e = end.split('-');
          var minyear = new Date();
          var maxyear = new Date();
          minyear.setFullYear(s[0]);// 开始年
          maxyear.setFullYear(e[0]);// 结束年
          var curryear = minyear;
          // eslint-disable-next-line no-unused-vars
          const yeararr = [];
          // eslint-disable-next-line no-unmodified-loop-condition
          while (curryear <= maxyear) {
            var year = curryear.getFullYear();
            result[year] = [];
            curryear.setFullYear(year + 1);
          }
          var min = new Date();
          var max = new Date();
          min.setFullYear(s[0], s[1] * 1 - 1);// 开始月
          max.setFullYear(e[0], e[1] * 1 - 1);// 结束月
          var curr = min;
          let temmonth = '';
          // eslint-disable-next-line no-unmodified-loop-condition
          while (curr <= max) {
            var month = curr.getMonth();
            if (month + 1 < 10) {
              temmonth = '0' + (month + 1);
            } else {
              temmonth = month + 1;
            }
            result[this.$moment(curr).format('YYYY')].push(temmonth);
            curr.setMonth(month + 1);
          }
            //  这部分可以自己写
          const list = [];
          if (result) {
            for (const curryearKey in result) {
              result[curryearKey].forEach((item) => {
                list.push(`${curryearKey}-${item}`);
              });
            }
          }
          // var str = curr.getFullYear() + '-' + (month.toString().padStart(2, '0'));
          return list;
        }

结果
