RegEx not working in IMaskInput

[easoftwareGit]

I cannot get my RegEx mask to work in the IMaskInput.
The RegEx is
/^\d(\d)?(,\d(\d)?)*$/
one or two digits, optional comma one or two digits. optional part repeats as needed
It works correctly at rexex101.com

I copied the code from the example, here is my code;

`import { useRef } from "react";
import { IMaskInput } from 'react-imask';

export const TestForm = () => {
// use ref to get access to internal "masked = ref.current.maskRef"
const ref = useRef(null);
const inputRef = useRef(null);

return (
<>
...

...
</>
)
} `

In my test, I can enter the first one or two digits, but the comma is never accepted. I have tried all three different values for the unmask prop (true | false | 'typed'), but I get the same results.

Thanks for any help.

Hi @easoftwareGit,

Your regexp does not match incomplete string like “1,”. But it should match any of intermediate value also. Or you probably can use number mask for it.

Thanks. That did the trick. I did not know I needed to have the RegEx accept an incomplete string.

New RegEx of /\d(\d)?(,(\d(\d)?)?)*$/ works!
