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

var d = new Date("Sun May 1,2014");

var year  = d.getFullYear();
var month = d.getMonth() + 1;
var day   = d.getDate(); 

month = checkZero(month);             
day   = checkZero(day);

var date = "";

date += year;
date += "-";
date += month;
date += "-";
date += day;

document.querySelector("#display").innerHTML = date;
    
function checkZero(i) 
{
    if (i < 10) 
    {
        i = "0" + i
    };  // add zero in front of numbers < 10

    return i;
}
