Javascript正则表达式，用于验证时间格式“ 09:15 AM”

Question

我尝试使用以下正则表达式，但无法正常工作。

/^([01]?[0-9]|2[0-3]):[0-5][0-9]{2}(AM|PM)/

Answer 1

You can try using this regex:

^(0?[1-9]|1[012])(:[0-5]\d) [APap][mM]$

Answer 2

你可以这样尝试

/^[1-12]:[0-59](A|P)M$/i

Answer 3

You are missing space before AM|PM and there is unnecessary {2} The following changes works for me:

^([01]?[0-9]|2[0-3]):[0-5][0-9] (AM|PM)

On the string

09:15 AM
