Question

I currently have this…

sanitizeNumber = function ( dirtyNumber ){
    // remove any non-digits from the number
    return dirtyNumber.replace(/[^\d.]/g, "");
}

.. but it appears to be allowing decimal points through.

How can I remove absolutely everything except for the digits from 0 to 9?

Answer 1

You shoud remove the . after the \d

sanitizeNumber = function ( dirtyNumber ){
    // remove any non-digits from the number
    return dirtyNumber.replace(/\D/g, "");
}
