I want to validate a string which is a duration (time spent) for doing a task:
2h35m
2h 35m
I have a html input and I want to validate it.
I found the solution:
^([0-1]?[0-9]|2[0-3])h([0-5][0-9]m)$
which works for 2h35m
I tried
^([0-1]?[0-9]|2[0-3])[h ]([0-5][0-9]m)$
where the character class [h ] will match the h char or a whitespace, but it does not work ok.
It matches the 2h35m but don't matches 2h 35m.
Any suggestions please? Thanks.
EDIT
a solution for the following formats
2
05
19
23
2h
05h
23h
01h50
1h02m
10h 30m
23h 59m
is here:
^(([0-1]?[0-9]|2[0-3])h?|([0-1]?[0-9]|2[0-3])h ?[0-5][0-9]m?)$
I share a better answer for someone who will need this.
