javascript date to string

Question

Here is what I need to do.

Get Date, convert to string and pass it over to a third party utility. The response from the library will have date in string format as I passed it. So, I need to convert the date to string like 20110506105524 (YYYYMMDDHHMMSS)

function printDate() {
    var temp = new Date();
    var dateStr = temp.getFullYear().toString() + 
                  temp.getMonth().toString() + 
                  temp.getDate().toString() +
                  temp.getHours().toString() + 
                  temp.getMinutes().toString() + 
                  temp.getSeconds().toString();

    debug (dateStr );
}

The problem with above is that for months 1-9, it prints one digit. How can I change it to print exactly 2 digits for month, date ...

Answer 1

You will need to pad with "0" if its a single digit & note getMonth returns 0..11 not 1..12

function printDate() {
    var temp = new Date();
    var dateStr = padStr(temp.getFullYear()) +
                  padStr(1 + temp.getMonth()) +
                  padStr(temp.getDate()) +
                  padStr(temp.getHours()) +
                  padStr(temp.getMinutes()) +
                  padStr(temp.getSeconds());
    debug (dateStr );
}

function padStr(i) {
    return (i < 10) ? "0" + i : "" + i;
}

Relying on JQuery Datepicker, but it could be done easily:

var mydate = new Date();
$.datepicker.formatDate('yy-mm-dd', mydate);
