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。

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())
其他回答
不是最短的,而是简单的,不可变的,没有依赖关系
function datesArray(start, end) {
let result = [], current = new Date(start);
while (current <= end)
result.push(current) && (current = new Date(current)) && current.setDate(current.getDate() + 1);
return result;
}
使用
函数datesArray(start, end) { let result = [], current = new Date(start); While (current <= end) result.push(current) && (current = new Date(current)) && current. setdate (current. getdate () + 1); 返回结果; } / /使用 const test = datesArray( 新的日期(“2020-02-26”), 新日期(“2020-03-05”) ); 对于(设I = 0;I < test.length;I ++) { console.log ( 测试[我].toISOString () .slice (0, 10) ); }
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);
});
希望对你有所帮助
我喜欢这样做
// hours * minutes * seconds * milliseconds
const DAY_IN_MS = 24 * 60 * 60 * 1000
/**
* Get range of dates
* @param {Date} startDate
* @param {Number} numOfDays
* @returns {array}
*/
const dateRange = (startDate, numOfDays) => {
const startDateMs = startDate.getTime()
// get array of days and map it to Date object
return [...Array(numOfDays).keys()].map(i => new Date(startDateMs + i * DAY_IN_MS))
}
function (startDate, endDate, addFn, interval) {
addFn = addFn || Date.prototype.addDays;
interval = interval || 1;
var retVal = [];
var current = new Date(startDate);
while (current <= endDate) {
retVal.push(new Date(current));
current = addFn.call(current, interval);
}
return retVal;
}
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>
