Javascript 将日数组拆分为月

我有一系列的日常需求。数组中的第一个元素表示开始日期。我需要将每日需求转换为每月需求的数组

我尝试了以下方法：

const monthSize=[1,2,3]；
常数起始日期=力矩（1535328000000）；
控制台日志（起始日期）；
常数dailyReq=[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0,0,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0,0,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0,0,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0,0,0,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0,0,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0,0,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0,0,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0,0,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0.7228819444444444,0];
const result=dailyReq.map（（e，i）=>{
返回i%monthSize==0？dailyReq.slice（i，i+monthSize）：null；
}).过滤器（（e）=>{
返回e；
});
log（result.map（g=>g.reduce（（a，b=>a+b，0）））

您可以简单地按月分组，然后获得每个值的长度

const dailyReq=[1,1,0,0,1,1,1,1,0,0,1,1,1,0,1,1,1,1,0,1,1,1,1,1,1,1,1,0,0,1,1,1,1,0,0,0,1,1,1,1,1,1,1,0,0,0,1,0,1,1,1,1,1,0,0,1]；
常数起始日期=力矩（1521072000000）；
const monthly=[…dailyReq.reduce（（a，b，i）=>{
如果（i>0）开始日期，则添加（1，'天'）；
返回b==0？a:a.set（startDate.month（），（a.get（startDate.month（））| |[]）.concat（b））；
}，新映射）。值（）].Map（e=>e.length）；
console.log（每月）；

什么是

monthSize

？你能用文字解释一下获得

12,20,10

所需的逻辑是什么吗？如果

开始日期

不相关，请随意删除它以获得@CertainPerformance，这样我就有了一个显示每日值的表。我可以根据每日值切换到查看每周、每月等s、 查看数组和开始日期，我知道

[12,20,10]

是每个月的值，即月份是3月，开始日期是该月的第15天。因此，值

12

是从第15天到3月底31天的值之和。我为您制作了一个片段
