Question

I searched a lot and can’t find the solution for this RegExp (I have to say I’m not very experienced in Reg. Expressions).

I would like to test a number between 1 and 36, excluding 0 and 37 and above.

What I’ve got so far and almost works (it doesn’t accept 17, 18, 19, 27, 28, 29)…

^[1-9]{1}$|^[1-3]{1}[0-6]{1}$|^36$;

Can someone help me please?

Answer 1

You know about \d, right?

^([1-9]|[12]\d|3[0-6])$

Try this in console:

function test() {
    for(var i = 0; i < 100; i++) {
        if (/^([1-9]|[12]\d|3[0-6])$/.test(i.toString()) != (i >= 1 && i <=36)) {
            document.write(i + "fail");
        }
                else
                document.write(i + "pass");
        document.write("<br/>");
    }
}
