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。

这可能会帮助到一些人,
您可以从中获得行输出,并根据需要格式化row_date对象。
var from_date = '2016-01-01';
var to_date = '2016-02-20';
var dates = getDates(from_date, to_date);
console.log(dates);
function getDates(from_date, to_date) {
var current_date = new Date(from_date);
var end_date = new Date(to_date);
var getTimeDiff = Math.abs(current_date.getTime() - end_date.getTime());
var date_range = Math.ceil(getTimeDiff / (1000 * 3600 * 24)) + 1 ;
var weekday = ["SUN", "MON", "TUE", "WED", "THU", "FRI", "SAT"];
var months = ["JAN", "FEB", "MAR", "APR", "MAY", "JUN", "JUL", "AUG", "SEP", "OCT", "NOV", "DEC"];
var dates = new Array();
for (var i = 0; i <= date_range; i++) {
var getDate, getMonth = '';
if(current_date.getDate() < 10) { getDate = ('0'+ current_date.getDate());}
else{getDate = current_date.getDate();}
if(current_date.getMonth() < 9) { getMonth = ('0'+ (current_date.getMonth()+1));}
else{getMonth = current_date.getMonth();}
var row_date = {day: getDate, month: getMonth, year: current_date.getFullYear()};
var fmt_date = {weekDay: weekday[current_date.getDay()], date: getDate, month: months[current_date.getMonth()]};
var is_weekend = false;
if (current_date.getDay() == 0 || current_date.getDay() == 6) {
is_weekend = true;
}
dates.push({row_date: row_date, fmt_date: fmt_date, is_weekend: is_weekend});
current_date.setDate(current_date.getDate() + 1);
}
return dates;
}

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));
@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;
}
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))
}
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"]
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;
}
