Regex define: YYYY-NNN/EXP
- YYYY: exactly 4 number 0000 -> 9999
- NNN: exactly 3 number 000 -> 999
- /: optional
- EXP: any character, optional
My regex: /^(\d{4})-(\d{3})(\/)?([\s\S]*)$/
I want to value exactly 2022-001 or 2022-001/anything. But I check value is 2022-001fsd, it match.
Is there anyway regex value exactly 2022-001 or 2022-001/anything?
Thanks!

You need to make the trailing portion of your pattern optional using the ? character, e.g.
^\d{4}-\d{3}(?:/\S )?$
