and this problem.
1 digit, 2 digits, 3 digits
1 10, 100
I want users to stop typing, especially for 3 digits.


I don’t understand what you said by full-width and half-width. Can you expand on that?

I don’t think there’s a way to do that, a workaround is you don’t allow users to submit if the number exceeds the digits you allow. Let’s say if you allow 2 digits but the number is > 99 then you don’t allow submitting.

Thanks! Itried it, I finished.
