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ES6,你有Array.from意味着你可以写一个非常优雅的函数,它允许动态间隔(小时,天,月)。
function getDates(startDate, endDate, interval) { const duration = endDate - startDate; const steps = duration / interval; return Array.from({length: steps+1}, (v,i) => new Date(startDate.valueOf() + (interval * i))); } const startDate = new Date(2017,12,30); const endDate = new Date(2018,1,3); const dayInterval = 1000 * 60 * 60 * 24; // 1 day const halfDayInterval = 1000 * 60 * 60 * 12; // 1/2 day console.log("Days", getDates(startDate, endDate, dayInterval)); console.log("Half Days", getDates(startDate, endDate, halfDayInterval));

var listDate = [];
var startDate ='2017-02-01';
var endDate = '2017-02-10';
var dateMove = new Date(startDate);
var strDate = startDate;
while (strDate < endDate){
var strDate = dateMove.toISOString().slice(0,10);
listDate.push(strDate);
dateMove.setDate(dateMove.getDate()+1);
};
console.log(listDate);
//["2017-02-01", "2017-02-02", "2017-02-03", "2017-02-04", "2017-02-05", "2017-02-06", "2017-02-07", "2017-02-08", "2017-02-09", "2017-02-10"]
注意:我知道这与要求的解决方案略有不同,但我认为许多人会发现它很有用。
如果你想找到两个日期之间的每个“x”间隔(天、月、年等等),moment.js和moment-range扩展包可以实现这个功能。
例如,要找出两个日期之间的每个30天:
window['moment-range'].extendMoment(moment);
var dateString = "2018-05-12 17:32:34.874-08";
var start = new Date(dateString);
var end = new Date();
var range1 = moment.range(start, end);
var arrayOfIntervalDates = Array.from(range1.by('day', { step: 30 }));
arrayOfIntervalDates.map(function(intervalDate){
console.log(intervalDate.format('YY-M-DD'))
});
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));
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) ); }
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>
