js如何获取两个时间中的所有年月？

function getYearAndMonth(start, end) {
    var result = [];
    var starts = start.split('-');
    var ends = end.split('-');
    var staYear = parseInt(starts[0]);
    var staMon = parseInt(starts[1]);
    var endYear = parseInt(ends[0]);
    var 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});
        }
    }

    return result;
