Answers:
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;
}
startDate
和中节省时间endDate
?因为如果startDate
时间晚于stopDate
时间,那么结果中将不包括时间stopDate
,对吗?
试试这个,记得包括一下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 currentDate = moment(startDate);
如果您在同一时刻两次使用此方法,那么您会感到困惑,为什么它第一次起作用。发生这种情况是因为javascript通过引用传递对象,因此该函数最终使用了startDate两次(已经进行了突变)。修补以上修复程序可确保您对函数范围内的新且独特的moment js对象感到困惑。检查这个小提琴
我看了上面所有的东西。最终写了自己。您不需要为此的momentjs。本机的for循环就足够了,并且最有意义,因为存在for循环来计算范围内的值。
一线:
var getDaysArray = function(s,e) {for(var a=[],d=new Date(s);d<=e;d.setDate(d.getDate()+1)){ a.push(new Date(d));}return a;};
长版
var getDaysArray = function(start, end) {
for(var arr=[],dt=new Date(start); dt<=end; dt.setDate(dt.getDate()+1)){
arr.push(new Date(dt));
}
return arr;
};
列出以下日期:
var daylist = getDaysArray(new Date("2018-05-01"),new Date("2018-07-01"));
daylist.map((v)=>v.toISOString().slice(0,10)).join("")
/*
Output:
"2018-05-01
2018-05-02
2018-05-03
...
2018-06-30
2018-07-01"
*/
从过去的日期到现在的天数:
var daylist = getDaysArray(new Date("2018-05-01"),new Date());
daylist.map((v)=>v.toISOString().slice(0,10)).join("")
getDaysArray
办?不在这之间的日子。
for (var arr=[], dt=new Date(start), ...)
。;-)
我使用moment.js和Twix.js,它们为日期和时间处理提供了很好的支持
var itr = moment.twix(new Date('2012-01-15'),new Date('2012-01-20')).iterate("days");
var range=[];
while(itr.hasNext()){
range.push(itr.next().toDate())
}
console.log(range);
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");

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;
}
如果您使用的是时刻,则可以使用其“官方插件”来确定范围moment-range
,然后变得微不足道。
矩范围节点示例:
const Moment = require('moment');
const MomentRange = require('moment-range');
const moment = MomentRange.extendMoment(Moment);
const start = new Date("11/30/2018"), end = new Date("09/30/2019")
const range = moment.range(moment(start), moment(end));
console.log(Array.from(range.by('day')))
瞬间范围浏览器示例:
window['moment-range'].extendMoment(moment);
const start = new Date("11/30/2018"), end = new Date("09/30/2019")
const range = moment.range(moment(start), moment(end));
console.log(Array.from(range.by('day')))
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.2/moment.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment-range/4.0.1/moment-range.js"></script>
date fns示例:
如果您使用的date-fns
则eachDay
是你的朋友,你迄今为止最短和最简洁的答案得到:
console.log(dateFns.eachDay(
new Date(2018, 11, 30),
new Date(2019, 30, 09)
))
<script src="https://cdnjs.cloudflare.com/ajax/libs/date-fns/1.29.0/date_fns.min.js"></script>
刚遇到这个问题,最简单的方法就是使用力矩:
您需要先安装瞬间和瞬间范围:
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)
我已经使用@Mohammed Safeer解决方案一段时间了,并且进行了一些改进。在控制器中工作时,使用格式化的日期是一种不好的做法。moment().format()
应该仅用于视图中的显示目的。还要记住,要moment().clone()
确保与输入参数分开,这意味着输入日期不会更改。我强烈建议您在处理日期时使用moment.js。
用法:
startDate
,endDate
参数interval
参数是可选的,默认为“天”。使用由.add()
方法(moment.js)支持的间隔。在这里更多细节total
在以分钟为单位指定间隔时,此参数很有用。默认为1。调用:
var startDate = moment(),
endDate = moment().add(1, 'days');
getDatesRangeArray(startDate, endDate, 'minutes', 30);
功能:
var getDatesRangeArray = function (startDate, endDate, interval, total) {
var config = {
interval: interval || 'days',
total: total || 1
},
dateArray = [],
currentDate = startDate.clone();
while (currentDate < endDate) {
dateArray.push(currentDate);
currentDate = currentDate.clone().add(config.total, config.interval);
}
return dateArray;
};
使用ES6,您可以使用Array.from,这意味着您可以编写一个非常优雅的函数,该函数允许动态间隔(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));
new Date(2017,12,30)
是2018年1月30日,对我来说日期范围开始于2018年1月29日。并非所有的天都是8.64e7毫秒(24小时)长,可以看到夏令时。;-)
我最近正在使用moment.js,以下是技巧。
function getDateRange(startDate, endDate, dateFormat) {
var dates = [],
end = moment(endDate),
diff = endDate.diff(startDate, 'days');
if(!startDate.isValid() || !endDate.isValid() || diff <= 0) {
return;
}
for(var i = 0; i < diff; i++) {
dates.push(end.subtract(1,'d').format(dateFormat));
}
return dates;
};
console.log(getDateRange(startDate, endDate, dateFormat));
结果将是:
["09/03/2015", "10/03/2015", "11/03/2015", "12/03/2015", "13/03/2015", "14/03/2015", "15/03/2015", "16/03/2015", "17/03/2015", "18/03/2015"]
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"]
var
之前strDate
!
我用这个功能
function getDatesRange(startDate, stopDate) {
const ONE_DAY = 24*3600*1000;
var days= [];
var currentDate = new Date(startDate);
while (currentDate <= stopDate) {
days.push(new Date (currentDate));
currentDate = currentDate - 1 + 1 + ONE_DAY;
}
return days;
}
我正在使用简单的while循环来计算日期之间
var start = new Date("01/05/2017");
var end = new Date("06/30/2017");
var newend = end.setDate(end.getDate()+1);
end = new Date(newend);
while(start < end){
console.log(new Date(start).getTime() / 1000); // unix timestamp format
console.log(start); // ISO Date format
var newDate = start.setDate(start.getDate() + 1);
start = new Date(newDate);
}
注意:我知道这与请求的解决方案略有不同,但是我认为许多人会发现它很有用。
如果要查找两个日期之间的每个“ x”间隔(天,月,年等),moment.js和力矩范围扩展包将启用此功能。
例如,要查找两个日期之间的第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'))
});
生成年份数组:
const DAYS = () => {
const days = []
const dateStart = moment()
const dateEnd = moment().add(30, ‘days')
while (dateEnd.diff(dateStart, ‘days') >= 0) {
days.push(dateStart.format(‘D'))
dateStart.add(1, ‘days')
}
return days
}
console.log(DAYS())
为月份生成一个数组:
const MONTHS = () => {
const months = []
const dateStart = moment()
const dateEnd = moment().add(12, ‘month')
while (dateEnd.diff(dateStart, ‘months') >= 0) {
months.push(dateStart.format(‘M'))
dateStart.add(1, ‘month')
}
return months
}
console.log(MONTHS())
几天生成一个数组:
const DAYS = () => {
const days = []
const dateStart = moment()
const dateEnd = moment().add(30, ‘days')
while (dateEnd.diff(dateStart, ‘days') >= 0) {
days.push(dateStart.format(‘D'))
dateStart.add(1, ‘days')
}
return days
}
console.log(DAYS())
您可以使用momentJS轻松完成
为您的依赖增加时间
npm i moment
然后将其导入您的文件中
var moment = require("moment");
然后使用以下代码获取两个日期之间所有日期的列表
let dates = [];
let currDate = moment.utc(new Date("06/30/2019")).startOf("day");
let lastDate = moment.utc(new Date("07/30/2019")).startOf("day");
do {
dates.push(currDate.clone().toDate());
} while (currDate.add(1, "days").diff(lastDate) < 0);
dates.push(currDate.clone().toDate());
console.log(dates);
这可能会帮助某人,
您可以从中获取行输出,并根据需要设置row_date对象的格式。
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;
}

这是一种固定方法,可以接受Moment日期或字符串或混合物作为输入,并生成日期数组作为Moment日期。如果您不希望将转折日期作为输出,请更改该map()
方法返回的内容。
const moment = require('moment');
// ...
/**
* @param {string|import('moment').Moment} start
* @param {string|import('moment').Moment} end
* @returns {import('moment').Moment[]}
*/
const getDateRange = (start, end) => {
const s = moment.isMoment(start) ? start : moment(start);
const e = moment.isMoment(end) ? end : moment(end);
return [...Array(1 + e.diff(s, 'days')).keys()].map(n => moment(s).add(n, 'days'));
};
@softvar的解决方案,但包括工作日期选项
/**
* 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;
}
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);
});
