var range = getDates(new Date(), new Date().addDays(7));
我想“范围”是一个日期对象的数组,一个为两个日期之间的每一天。
诀窍在于它还应该处理月份和年份的边界。

使用JavaScript
const getDatesBetween = (startDate, endDate, includeEndDate) => {
const dates = [];
const currentDate = startDate;
while (currentDate < endDate) {
dates.push(new Date(currentDate));
currentDate.setDate(currentDate.getDate() + 1);
}
if (includeEndDate) dates.push(endDate);
return dates;
};
使用打印稿
const getDatesBetween = (
startDate: Date,
endDate: Date,
includeEndDate?: boolean
) => {
const dates = [];
const currentDate = startDate;
while (currentDate < endDate) {
dates.push(new Date(currentDate));
currentDate.setDate(currentDate.getDate() + 1);
}
if (includeEndDate) dates.push(endDate);
return dates;
};
例子
console.log(getDatesBetween(new Date(2020, 0, 1), new Date(2020, 0, 3)));
console.log(getDatesBetween(new Date(2020, 0, 1), new Date(2020, 0, 3), true));

如果你正在使用moment,那么你可以使用他们的“官方插件”来表示moment-range,然后这就变得微不足道了。
矩距节点示例:
const Moment = require('moment');
const MomentRange = require('moment-range');
const moment = MomentRange.extendMoment(Moment);
const start = new Date("11/30/2018"), end = new Date("09/30/2019")
const range = moment.range(moment(start), moment(end));
console.log(Array.from(range.by('day')))
Moment-range浏览器示例:
窗口(“moment-range”).extendMoment(时刻); const start = new Date("11/30/2018"), end = new Date("09/30/2019") Const range = moment.range(moment(start), moment(end)); console.log (Array.from(接触式(天))) < script src = " https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.2/moment.min.js " > < /脚本> < script src = " https://cdnjs.cloudflare.com/ajax/libs/moment-range/4.0.1/moment-range.js " > < /脚本>
日期FNS举例:
如果你使用date-fns,那么eachDay是你的朋友,你会得到迄今为止最短和最简洁的答案:
console.log (dateFns.eachDay ( 新日期(2018,11,30), 新日期(2019年30月09日) )) < script src = " https://cdnjs.cloudflare.com/ajax/libs/date-fns/1.29.0/date_fns.min.js " > < /脚本>
我看了上面所有的。最后我自己开始写作。你不需要花时间。原生的for循环就足够了,而且最有意义,因为for循环的存在是为了计算一个范围内的值。
一个衬套:
var getDaysArray = function(s,e) {for(var a=[],d=new Date(s);d<=new Date(e);d.setDate(d.getDate()+1)){ a.push(new Date(d));}return a;};
长版本
var getDaysArray = function(start, end) {
for(var arr=[],dt=new Date(start); dt<=new Date(end); dt.setDate(dt.getDate()+1)){
arr.push(new Date(dt));
}
return arr;
};
列出中间的日期:
var daylist = getDaysArray(new Date("2018-05-01"),new Date("2018-07-01"));
daylist.map((v)=>v.toISOString().slice(0,10)).join("")
/*
Output:
"2018-05-01
2018-05-02
2018-05-03
...
2018-06-30
2018-07-01"
*/
从过去日期到现在的日子:
var daylist = getDaysArray(new Date("2018-05-01"),new Date());
daylist.map((v)=>v.toISOString().slice(0,10)).join("")
Generate an array of years: const DAYS = () => { const days = [] const dateStart = moment() const dateEnd = moment().add(30, ‘days') while (dateEnd.diff(dateStart, ‘days') >= 0) { days.push(dateStart.format(‘D')) dateStart.add(1, ‘days') } return days } console.log(DAYS()) Generate an arrays for month: const MONTHS = () => { const months = [] const dateStart = moment() const dateEnd = moment().add(12, ‘month') while (dateEnd.diff(dateStart, ‘months') >= 0) { months.push(dateStart.format(‘M')) dateStart.add(1, ‘month') } return months } console.log(MONTHS()) Generate an arrays for days: const DAYS = () => { const days = [] const dateStart = moment() const dateEnd = moment().add(30, ‘days') while (dateEnd.diff(dateStart, ‘days') >= 0) { days.push(dateStart.format(‘D')) dateStart.add(1, ‘days') } return days } console.log(DAYS())
这是另外几行使用date-fns库的解决方案:
const {format, differenceInDays, addDays} = dateFns; const getRangeDates = (startDate, endDate) => { const days = differenceInDays(endDate, startDate); console.log([…数组(天+ 1). keys ()] . map ((i) = >格式(addDays (startDate可以,我),YYYY-MM-DD))); }; getRangeDates (' 2021-06-01 ', ' 2021-06-05 '); < script src = " https://cdnjs.cloudflare.com/ajax/libs/date-fns/1.30.1/date_fns.js " > < /脚本>
Date.prototype.addDays = function(days) {
var date = new Date(this.valueOf());
date.setDate(date.getDate() + days);
return date;
}
function getDates(startDate, stopDate) {
var dateArray = new Array();
var currentDate = startDate;
while (currentDate <= stopDate) {
dateArray.push(new Date (currentDate));
currentDate = currentDate.addDays(1);
}
return dateArray;
}
