I'm trying to figure out, how to create a javascript array of names of ie. last 7 days starting from today.

I know getDay() will return a number of the day, which I can then use as an index to access an element of an array containing days of the week.
This will give me the name of today, but I need to go back chronologically to create an array of last few days I couldn't find anything similar to this problem on web.

Any elegant solution for this? jQuery perhaps?

• javascript
• jquery
• arrays

• you mean like ['thursday', 'wednesday', ..., 'friday'] ? – Mivaweb Commented Nov 27, 2014 at 14:44
• Which language would you want the day names in? – Rory McCrossan Commented Nov 27, 2014 at 14:45
• @Rory McCrossan - whatever, but can be English for start – robjez Commented Nov 27, 2014 at 14:46

const days = ['monday', 'tuesday', 'wednesday', 'thursday', 
              'friday', 'saterday', 'sunday'];
var goBackDays = 7;

var today = new Date();
var daysSorted = [];

for(var i = 0; i < goBackDays; i++) {
  var newDate = new Date(today.setDate(today.getDate() - 1));
  daysSorted.push(days[newDate.getDay()]);
}

alert(daysSorted);

function myFunction(day) {   
   var weekday =["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"]
   return weekday[day];    
}
var currentDate = new Date().getDay();
var week=[0,1,2,3,4,5,6];
var a=week.splice(currentDate);
var loopWeek=a.concat(week);
var freshWeek=[]; 
for(var i=0;i<loopWeek.length;i++){
freshWeek.push(myFunction(loopWeek[i]))
}
console.log(freshWeek);

Maybe not the most elegant way:

var numdays = 7; // Change it to the number of days you need
var d = new Date();
var n = d.getDay();
var weekday = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"]
var myArray = new Array(numdays);
for(var i=0;i<numdays;i++){
  myArray[i]=weekday[(n-i+numdays)%7];
}
console.log(myArray); // Result:  ["Thursday", "Wednesday", "Tuesday", "Monday", "Sunday", "Saturday", "Friday"]
