Question

I have a DateTime string ISO8601 formated

2012-10-06T04:13:00+00:00

and the following Regex which does not match this string

#(\d{4})-(\d{2})-(\d{2})T(\d{2})\:(\d{2})\:(\d{2})\+(\d{2})\:(\d{2})#

I can’t figure out why it does not match.

I escaped metacharacters, for me it seems to be OK.

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');
}​
