获取两个日期之间的年月(可跨年)

1、例如：输入起止时间，获取以下内容

 2、方法如下：

getYearAndMonth(start, end) {
      let month;
      const result = [];
      const newResult = [];
      const starts = start.split('-');
      const ends = end.split('-');
      let staYear = parseInt(starts[0]);
      let staMon = parseInt(starts[1]) - 1;
      const endYear = parseInt(ends[0]);
      const endMon = parseInt(ends[1]);
      while (staYear <= endYear) {
        if (staYear === endYear) {
          while (staMon < endMon) {
            staMon++;
            result.push({year: staYear, month: staMon});
          }
          staYear++;
        } else {
          staMon++;
          if (staMon > 12) {
            staMon = 1;
            staYear++;
          }
          result.push({year: staYear, month: staMon});
        }
      }
      for(let i=0; i<result.length; i++){
        const year = result[i].year;
        const monthinit = result[i].month;
        if(monthinit<10){
          month = '0' + monthinit;
        }else{
          month = monthinit + '';
        }
        const ym = year + '-' + month;
        newResult.push(ym);
      }
      console.log(result);
      console.log(newResult);
      return newResult;  //return 内容可以根据实际返回 
}

3、结果如下：
