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;
}

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));
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/
我最近在用moment.js工作,下面做了一个戏法。
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"]
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));
我使用moment.js和Twix.js,它们为日期和时间操作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);
