7

我想打印这样的东西（7 天日历），但可以从我想要的任何日期开始。

Monday, 1 January 2011
Tuesday, 2 January 2011
Wednesday, 3 January 2011
Thursday, 4 January 2011
Friday, 5 January 2011
Saturday, 6 January 2011
Sunday, 7 January 2011

例如，我想从 2 月 22 日开始显示接下来的 7 天。不知道如何处理。

这似乎是您正在寻找的：

function GetDates(startDate, daysToAdd) {
    var aryDates = [];

    for (var i = 0; i <= daysToAdd; i++) {
        var currentDate = new Date();
        currentDate.setDate(startDate.getDate() + i);
        aryDates.push(DayAsString(currentDate.getDay()) + ", " + currentDate.getDate() + " " + MonthAsString(currentDate.getMonth()) + " " + currentDate.getFullYear());
    }

    return aryDates;
}

function MonthAsString(monthIndex) {
    var d = new Date();
    var month = new Array();
    month[0] = "January";
    month[1] = "February";
    month[2] = "March";
    month[3] = "April";
    month[4] = "May";
    month[5] = "June";
    month[6] = "July";
    month[7] = "August";
    month[8] = "September";
    month[9] = "October";
    month[10] = "November";
    month[11] = "December";

    return month[monthIndex];
}

function DayAsString(dayIndex) {
    var weekdays = new Array(7);
    weekdays[0] = "Sunday";
    weekdays[1] = "Monday";
    weekdays[2] = "Tuesday";
    weekdays[3] = "Wednesday";
    weekdays[4] = "Thursday";
    weekdays[5] = "Friday";
    weekdays[6] = "Saturday";

    return weekdays[dayIndex];
}

var startDate = new Date();
var aryDates = GetDates(startDate, 7);
console.log(aryDates);​
​

结果（截至今天）：

["Thursday, 5 April 2012",
 "Friday, 6 April 2012", 
 "Saturday, 7 April 2012", 
 "Sunday, 8 April 2012", 
 "Monday, 9 April 2012", 
 "Tuesday, 10 April 2012", 
 "Wednesday, 11 April 2012", 
 "Thursday, 12 April 2012"]

这是一个工作小提琴。

这是我使用Moment.js的解决方案

未来 7 天 

let days = [];
let daysRequired = 7

for (let i = 1; i <= daysRequired; i++) {
  days.push( moment().add(i, 'days').format('dddd, Do MMMM YYYY') )
}

console.log(days)
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js"></script>

以防万一您需要前 7 天

let days = [];
let daysRequired = 7

for (let i = daysRequired; i >= 1; i--) {
  days.push( moment().subtract(i, 'days').format('dddd, Do MMMM YYYY') )
}

console.log(days)
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js"></script>

初始日期：

var startingDay = new Date(year, month, day);

整整一周startingDay：

var thisDay = new Date();
for(var i=0; i<7; i++) {
  thisDay.setDate(startingDay.getDate() + i);
  console.log(thisDay.format());
}

格式化函数：

Date.prototype.format = function(){
    var months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];        
    var days = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
    return days[this.getDay()]
          +", "
          +this.getDate()
          +" "
          +months[this.getMonth()] 
          +" "
          +this.getFullYear();
};

var feb22 = new Date(2012, 1, 22);
var feb23 = new Date(feb22.getTime() + 1000*60*60*24);

...等等

您可以将变量 dateString 设置为您想要的任何值，并在循环中增加日期。然后你会得到日期，但我认为格式不同。

var dateString = '22 Feb 2012';
var actualDate = new Date(dateString);
var newDate;

for(var i=1; i<=7; i++){
 newDate = new Date(actualDate.getFullYear(), actualDate.getMonth(), actualDate.getDate()+i);
}

如果您需要从今天开始接下来的 7 个工作日

const isWeekday = (date) => {
	return date.weekday()!==0 && date.weekday()!==6
}

const weekdays=[];
let numberOfDaysRequired = 7
let addDaysBy = 1
moment.locale('en')
while(weekdays.length < numberOfDaysRequired)
{
  const d = moment().add(addDaysBy, 'days')
  if(isWeekday(d))
  {
  	weekdays.push(d.format('dddd, Do MMMM YYYY'))
  	
  }
  addDaysBy++;
}

console.log(weekdays)
