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));

@softvar的解决方案，但随后包括工作日期选项
/**
* Returns array of working days between two dates.
*
* @param {string} startDate
* The start date in yyyy-mm-dd format.
* @param {string} endDate
* The end date in yyyy-mm-dd format.
* @param {boolean} onlyWorkingDays
* If true only working days are returned. Default: false
*
* @return {array}
* Array of dates in yyyy-mm-dd string format.
*/
function getDates(startDate, stopDate, onlyWorkingDays) {
let doWd = typeof onlyWorkingDays ==='undefined' ? false : onlyWorkingDays;
let dateArray = [];
let dayNr;
let runDateObj = moment(startDate);
let stopDateObj = moment(stopDate);
while (runDateObj <= stopDateObj) {
dayNr = runDateObj.day();
if (!doWd || (dayNr>0 && dayNr<6)) {
dateArray.push(moment(runDateObj).format('YYYY-MM-DD'));
}
runDateObj = moment(runDateObj).add(1, 'days');
}
return dateArray;
}
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));
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;
}
这里是一个功能演示http://jsfiddle.net/jfhartsock/cM3ZU/
Array(7).fill().map((_,i) => dayjs().subtract(i, "day").format("YYYY-MM-DD"));
功能:
var dates = [],
currentDate = startDate,
addDays = function(days) {
var date = new Date(this.valueOf());
date.setDate(date.getDate() + days);
return date;
};
while (currentDate <= endDate) {
dates.push(currentDate);
currentDate = addDays.call(currentDate, 1);
}
return dates;
};
用法:
var dates = getDatesRange(new Date(2019,01,01), new Date(2019,01,25));
dates.forEach(function(date) {
console.log(date);
});
