RegEx - 时间验证（（h）h：mm） [英] RegEx - Time Validation ((h)h:mm)

问题描述

/^\d{1,2}[:][0-5][0-9]$/

就是我所拥有的。这将分钟限制在00-59。但是，它不会将时间限制在0到12之间。对于相似性和一致性，如果可能的话，我希望单独使用RegEx。

is what I have. this limits minutes to 00-59. It does not, however, limit hours to between 0 and 12. For similarity and uniformity I would like to do this with RegEx alone if possible.

我还会更多比如第一个数字是可选的。即09:30接受以及9:30。我玩了范围，但超出范围的东西总是可以接受的。

Further-more I would like the first digit to be optional. i.e. 09:30 accepted as well as 9:30. I played around with ranges, but something out of range is always acceptable.

推荐答案

/^(10|11|12|[1-9]):[0-5][0-9]$/

我认为您不希望0:50作为有效时间。

I don't think that you want 0:50 as a valid time either.
