Could I use j

Answer 1

Try this for all symbols:

inputField.value.replace(/(\...)(.)/, "$1");

or this for numbers:

inputField.value.replace(/(\.[0-9][0-9])([0-9])/, "$1");

I found this method here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace#Example:_Switching_words_in_a_string
