Regex: how to only allow integers greater than zero

Question

I have tried the following to only allow integers in my text box, this works great but it allows a zero in there. Is there anything else I can add to prevent a zero being added?

\d+

Answer 1

This will allow 10 but not 01, and it will allow only numbers consisting of digits, i.e., no periods or minus signs...but also no plus signs, scientific notation etc.
