Limit number of characters in input type number

Question

Im trying to limit to X number the characters in a input (type of number). ive tried a lot of options and none seems to work. I dont want to use the option tel as it needs t

Answer 1

Proper way 2020 for type number is to check on keydown validation and it should work like this: onkeypress="checkValidation(fieldValue);" <-- on input in html and in js:

checkValidation(a) {
    if (`${a}`.length < 8) {
        return true;
    } else {
        return false;
    }
}
