Format JavaScript date as yyyy-mm-dd
Question
I have a date with the format Sun May 11,2014
. How can I convert it to 2014-05-11
using JavaScript?
function taskDate(dateMilli) {
var d = (new Date(dateMilli) + '').split(' ');
d[2] = d[2] + ',';
return [d[0], d[1], d[2], d[3]].join(' ');
}
var datemilli = Date.parse('Sun May 11,2014');
console.log(taskDate(datemilli));
The code above gives me the same date format, sun may 11,2014
. How can I fix this?

You can do:
function formatDate(date) {
var d = new Date(date),
month = '' + (d.getMonth() + 1),
day = '' + d.getDate(),
year = d.getFullYear();
if (month.length < 2)
month = '0' + month;
if (day.length < 2)
day = '0' + day;
return [year, month, day].join('-');
}
Usage example:
alert(formatDate('Sun May 11,2014'));
Output:
2014-05-11

Just leverage the built-in toISOString
method that brings your date to the ISO 8601 format:
yourDate.toISOString().split('T')[0]
Where yourDate is your date object.
Edit: some guy wrote this to handle time zone in the comments:
const offset = yourDate.getTimezoneOffset()
yourDate = new Date(yourDate.getTime() + (offset*60*1000))
return yourDate.toISOString().split('T')[0]

I use this way to get the date in format yyyy-mm-dd :)
var todayDate = new Date().toISOString().slice(0,10);

The simplest way to convert your date to the yyyy-mm-dd format, is to do this:
var date = new Date("Sun May 11,2014");
var dateString = new Date(date.getTime() - (date.getTimezoneOffset() * 60000 ))
.toISOString()
.split("T")[0];
How it works:
new Date("Sun May 11,2014")
converts the string"Sun May 11,2014"
to a date object that represents the timeSun May 11 2014 00:00:00
in a timezone based on current locale (host system settings)new Date(date.getTime() - (date.getTimezoneOffset() * 60000 ))
converts your date to a date object that corresponds with the timeSun May 11 2014 00:00:00
in UTC (standard time) by subtracting the time zone offset.toISOString()
converts the date object to an ISO 8601 string2014-05-11T00:00:00.000Z
.split("T")
splits the string to array["2014-05-11", "00:00:00.000Z"]
[0]
takes the first element of that array
Demo
var date = new Date("Sun May 11,2014");
var dateString = new Date(date.getTime() - (date.getTimezoneOffset() * 60000 ))
.toISOString()
.split("T")[0];
console.log(dateString);

format = function date2str(x, y) {
var z = {
M: x.getMonth() + 1,
d: x.getDate(),
h: x.getHours(),
m: x.getMinutes(),
s: x.getSeconds()
};
y = y.replace(/(M+|d+|h+|m+|s+)/g, function(v) {
return ((v.length > 1 ? "0" : "") + eval('z.' + v.slice(-1))).slice(-2)
});
return y.replace(/(y+)/g, function(v) {
return x.getFullYear().toString().slice(-v.length)
});
}
Result:
format(new Date('Sun May 11,2014'), 'yyyy-MM-dd')
"2014-05-11

A combination of some of the answers:
var d = new Date(date);
date = [
d.getFullYear(),
('0' + (d.getMonth() + 1)).slice(-2),
('0' + d.getDate()).slice(-2)
].join('-');

If you don't have anything against using libraries, you could just use the Moments.js library like so:
var now = new Date();
var dateString = moment(now).format('YYYY-MM-DD');
var dateStringWithTime = moment(now).format('YYYY-MM-DD HH:mm:ss');
