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?

Answer 1

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');
