One or two numeric digits Regex

I have the below code. It works only when I have 2 digits. If I have 1 digit doesn't work. I want to work in both cases: one or two digit.
var numberRegex = /^[1-9][0-9]$/;
I've tried something like this but unfortunately doesn't work:
var numberRegex = /^[1-9]?[1-9][0-9]$/;
Thanks for support.

This works:

/^([0-9]{0,1}([1-9][0-9]){0,2})$/

Try this.

/^[0-9]|[0-9][0-9]$/

This should do the job. Using an Or operator does it.

Try this one out:

/^\d{1,2}$/;

Reading what you have it looks like you don't want to accept numbers like 01.

/^\d{1}|[1-9]\d{1}$/;
