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

Retrieve year, month, and day, and then put them together. Straight, simple, and accurate.

function formatDate(date) {
    var year = date.getFullYear().toString();
    var month = (date.getMonth() + 101).toString().substring(1);
    var day = (date.getDate() + 100).toString().substring(1);
    return year + "-" + month + "-" + day;
}

//Usage example:
alert(formatDate(new Date()));
