javascript - Javascript - 获取两个日期之间的日期数组

Question

var range = getDates(new Date(), new Date().addDays(7));

我希望“范围”是一个日期对象数组，两个日期之间的每一天都有一个。

诀窍是它也应该处理月份和年份的界限。

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;
}

我看了上面所有的。最后自己写了。你不需要 momentjs。一个原生的 for 循环就足够了，而且最有意义，因为存在一个 for 循环来计算一个范围内的值。

一个班轮：

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;
};

列出两者之间的日期：

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("")

    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');

我使用moment.js和Twix.js，它们为日期和时间处理提供了非常好的支持

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);

我在使用上面的答案时遇到了麻烦。由于当地夏令时 (DST) 导致的时区偏移，日期范围缺少单日。我使用 UTC 日期实现了一个版本来解决这个问题：

function dateRange(startDate, endDate, steps = 1) {
  const dateArray = [];
  let currentDate = new Date(startDate);

  while (currentDate <= new Date(endDate)) {
    dateArray.push(new Date(currentDate));
    // Use UTC date to prevent problems with time zones and DST
    currentDate.setUTCDate(currentDate.getUTCDate() + steps);
  }

  return dateArray;
}

const dates = dateRange('2020-09-27', '2020-10-28');
console.log(dates);

注意：是否应用某个时区或 DST，完全取决于您的语言环境。覆盖这通常不是一个好主意。使用UTC 日期可以缓解大多数与时间相关的问题。

奖励steps：您可以使用可选参数设置要创建时间戳的时间间隔。如果您希望将每周时间戳设置steps为7.

如果您正在使用时刻，那么您可以将他们的“官方插件”用于范围moment-range，然后这变得微不足道。

矩范围节点示例：

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')))

时刻范围浏览器示例：

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));

使用 ES6 你有 Array.from 意味着你可以编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));

刚刚遇到这个问题，最简单的方法是使用时刻：

您需要先安装矩和矩范围：

const Moment = require('moment');
const MomentRange = require('moment-range');
const moment = MomentRange.extendMoment(Moment);

const start = moment()

const range = moment.range(start, end)

我最近正在使用moment.js，以下是诀窍..

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：

我使用@Mohammed Safeer 解决方案已经有一段时间了，并且做了一些改进。在控制器中工作时使用格式化日期是一种不好的做法。moment().format()应仅用于视图中的显示目的。还要记住，moment().clone()确保与输入参数分离，这意味着输入日期不会改变。我强烈建议您在处理日期时使用 moment.js。

用法：

提供 moment.js 日期作为startDate,endDate参数的值
interval参数是可选的，默认为“天”。使用.add()方法（moment.js）支持的间隔。更多细节在这里
total以分钟为单位指定间隔时，参数很有用。它默认为 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);
    }

您可以使用 momentJS 轻松完成

为您的依赖项添加时刻

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());

d3js提供了许多方便的功能，并包括d3.time以便于日期操作

https://github.com/d3/d3-time

对于您的具体要求：

世界标准时间

var range = d3.utcDay.range(new Date(), d3.utcDay.offset(new Date(), 7));

或当地时间

var range = d3.timeDay.range(new Date(), d3.timeDay.offset(new Date(), 7));

range 将是一个日期对象数组，它们落在每天的第一个可能值上

您可以将 timeDay 更改为 timeHour、timeMonth 等，以获得不同时间间隔的相同结果

如果您不想创建另一个函数，这是一个不需要任何库的衬垫。只需用您的变量或日期值替换 startDate （在两个地方）和 endDate （它们是 js 日期对象）。当然，如果您愿意，可以将其包装在一个函数中

如果要查找两个日期之间的每个“x”间隔（天、月、年等），moment.js和moment-range扩展包启用此功能。

例如，要查找两个日期之间的第 30 天：

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);
