How to get datetime in JavaScript?

Question

How to get date time in JavaScript with format 31/12/2010 03:55 AM?

Answer 1

@Shadow Wizard's code should return 02:45 PM instead of 14:45 PM. So I modified his code a bit:

function getNowDateTimeStr(){
 var now = new Date();
 var hour = now.getHours() - (now.getHours() >= 12 ? 12 : 0);
return [[AddZero(now.getDate()), AddZero(now.getMonth() + 1), now.getFullYear()].join("/"), [AddZero(hour), AddZero(now.getMinutes())].join(":"), now.getHours() >= 12 ? "PM" : "AM"].join(" ");
}

//Pad given value to the left with "0"
function AddZero(num) {
    return (num >= 0 && num < 10) ? "0" + num : num + "";
}
