Q183 How can I format a number, e.g. 2, as 02 and 00002?

<script language="JavaScript"><!--
function padout(number) { return (number < 10) ? '0' + number : number; }

alert(padout(2));
//--></script>

<script language="JavaScript"><!--
function pad(number,length) {
    var str = '' + number;
    while (str.length < length)
        str = '0' + str;
    return str;
}

alert(pad(2,5));
//--></script>
