Format JavaScript date as yyyy-mm-dd

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



Usage example:

console.log(formatDate('Sun May 11,2014'));

Output:

2014-05-11
