Search for the relative keyCode and use them in your conditions. — techie_28

Check for the key codes 188 and 32, respectively. Whereas 188 is "comma", you may also want to check for 110 – "decimal point", for the character on your numpad (depending on keyboard layout, of course).

32 will be for Space.

188 will be for Comma(,).

So Add it in your if condition:

event.keyCode == 32 || event.keyCode == 188

See the whole list: KeyCode List

You can call this function:

var isValid = function(key) {

    var allowedCharacters = ['0','1','2','3','4','5','6','7','8','9',' ', ',']
    if (allowedCharacters.contains(key)) return true;
    return false;

};

How would you implement that in a keydown listener?

var key = String.fromCharCode(e.keyCode);
