菜鸟求大佬解答，很着急

  var startTime = "2020-11";
  var endTime = "2021-02";
  
   已知起/终月份，如何得到瞎下面这个数据

Answer 1

function zeroPrefix(val) {
    return (val + '').padStart(2, '0');
}

function getTimeInterval() {
    const [startYear, startMonth] = startTime.split('-');
    const [endYear, endMonth] = endTime.split('-');
    const startTimestamp = new Date(startYear, startMonth - 1).getTime();
    const endTimestamp = new Date(endYear, endMonth - 1).getTime();
    const intervals = [];
    let timestamp = startTimestamp;
    
    while (timestamp <= endTimestamp) {
        const now = new Date(timestamp);
        const year = now.getFullYear();
        const month = now.getMonth() + 1;
        
        intervals.push(`${year}-${zeroPrefix(month)}`);
        timestamp = new Date(year, month).getTime();
    }
    
    return intervals;
}
