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

If you are not concerned about negatives and silly numbers like 07, this will do:

/[1-9]\d*/

For a more robust solution, I suggest converting the matched string to integer and check if it fulfills your criteria.
