Question

How can i do the following:

I have a string

something#12

I need a regex that will get last two numbers from the string in range from 0 to 19. Note that nothing should be returned if the number after # is greater than 19, i need to ignore letters and special symbols either.

I have tried the following:

([0-9]{1}$)|([0-1]{1}[0-9]{1}$)

but it return last one or two numbers if i have a value greater than 19.

Answer 1

I think you want something like:

/\D[0-1]?\d$/g

The \D will match any non-digit, \d will match any number and you want to optionally (?) allow 0 or 1 in front.
