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)

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;

}

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/

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);
});
