Regex and ISO8601 formatted DateTime [duplicate]

Answer 1

Don't quote the regex when specifying a regex in js. Forward slash is enough.

alert($('#datepicker').val());

if($('#datepicker').val().match(
    /(\d{4})-(\d{2})-(\d{2})T(\d{2})\:(\d{2})\:(\d{2})[+-](\d{2})\:(\d{2})/
)) {
    alert('ok');
} else {
    alert('not ok');
}​
