正则表达式和ISO8601格式的DateTime [英] Regex and ISO8601 formatted DateTime

问题描述

我有一个DateTime字符串ISO8601格式化

I have a DateTime string ISO8601 formated

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

和以下不符合此字符串的正则表达式

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})#

我不知道为什么它不匹配。

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

我逃脱了元字符对我来说似乎是可以的。

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

推荐答案

在js中指定正则表达式时，不要引用正则表达式。正向斜杠就足够了。

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');
}​
