Wie bekomme ich die nächsten sieben Tage von X und Format in JS

Question

Ich möchte etwas wie das (ein 7-Tage-Kalender) drucken, aber mit der Möglichkeit, von jedem beliebigen Datum zu starten.

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 

So zum Beispiel möchte ich die nächsten sieben Tage ab 22 Februar zeigen. Hab keine Ahnung wie man damit umgeht.

Answer 1

Dies scheint zu sein, was du bist Suche nach:

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);​ 
​ 

Ergebnis (Stand heute):

["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"] 

Hier a working fiddle.

Answer 2

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

... und so weiter

Answer 3

können Sie die Variable datestring auf alles, was Sie und in der Schleife möchten Sie einfach den Tag erhöhen. Dann werden Sie die Daten bekommen, aber ich denke in einem anderen Format.

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); 
} 

Answer 4

Ein Anfangsdatum:

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

Eine ganze Woche von startingDay:

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

Die Formatierungsfunktion:

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(); 
}; 

Answer 5

Hier ist meine Lösung Moment.js

Nächste 7 Tage

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>

Nur für den Fall verwenden, wenn Sie vorherige 7 Tage

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)

Answer 6

Wenn Sie ab heute nächsten 7 Werktage brauchen

const isWeekday = (date) => { 
 
\t 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)) 
 
    { 
 
    \t weekdays.push(d.format('dddd, Do MMMM YYYY')) 
 
    \t 
 
    } 
 
    addDaysBy++; 
 
} 
 

 
console.log(weekdays)
