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>
