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。
当前回答
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;
}

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'))
});
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))
}
Array(7).fill().map((_,i) => dayjs().subtract(i, "day").format("YYYY-MM-DD"));
试试这个，记得加上moment js，
function getDates(startDate, stopDate) {
var dateArray = [];
var currentDate = moment(startDate);
var stopDate = moment(stopDate);
while (currentDate <= stopDate) {
dateArray.push( moment(currentDate).format('YYYY-MM-DD') )
currentDate = moment(currentDate).add(1, 'days');
}
return dateArray;
}
var boxingDay = new Date("12/26/2010");
var nextWeek = boxingDay*1 + 7*24*3600*1000;
function getDates( d1, d2 ){
var oneDay = 24*3600*1000;
for (var d=[],ms=d1*1,last=d2*1;ms<last;ms+=oneDay){
d.push( new Date(ms) );
}
return d;
}
getDates( boxingDay, nextWeek ).join("\n");
