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 ad

Answer 1

^(0*[1-9][0-9]*)$

This will allow "silly" numbers like 007 as well, but not 0 or 000 or an empty string.

Note that \d matches also digits from other character sets like ٠١٢٣٤٥٦٧٨٩. See: \d is less efficient than [0-9].

^ denotes the start, $ the end of the string. Together they ensure that the whole string is matched.
