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));
其他回答
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;
}

刚遇到这个问题,最简单的方法就是用moment:
你需要先安装moment和moment-range:
const Moment = require('moment');
const MomentRange = require('moment-range');
const moment = MomentRange.extendMoment(Moment);
const start = moment()
const end = moment().add(2, 'months')
const range = moment.range(start, end)
const arrayOfDates = Array.from(range.by('days'))
console.log(arrayOfDates)
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>
这里有一个不需要任何库的代码行,以防你不想创建另一个函数。只需用变量或日期值替换startDate(在两个地方)和endDate(这是js的日期对象)。当然,如果你愿意,你可以把它包装在一个函数中
Array(Math.floor((endDate - startDate) / 86400000) + 1).fill().map((_, idx) => (new Date(startDate.getTime() + idx * 86400000)))
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())
