Question

this question has already been asked but the solutions where not clear.

Im using Josh Bush\'s MaskedInput plugin for jQuery

What im trying to achieve is:

Answer 1

unmask is not a function. This is my way of use. autoUnmask: true

    $('#amount').inputmask('999.999.999.999', {
        numericInput: true,
        autoUnmask: true,
    });
