keyCode values for numeric keypad?

Question

Do the numbers on a numeric keypad have a different keycode than the numbers at the top of a keyboard?

Here is some JavaScript that is supposed to run on the keyup event, but only if the keycode is between 48 and 57. Here is the code:

$('#rollNum').keyup(function(e) {
    if(e.keyCode >= 48 && e.keyCode <= 57) { //0-9 only
        var max = 15;
        var textLen = $(this).val().length;
        var textLeft = max - textLen;
        . . . 

My problem is that this code only runs in response to the numbers entered at the top of the keyboard, but does not run in response to numbers entered from the numeric keypad.

I'm thinking the answer must be that the numeric keypad has different keyCode values, but how do I find out what those are?

Answer 1

The keycodes are different. Keypad 0-9 is Keycode 96 to 105

Your if statement should be:

if ((e.keyCode >= 48 && e.keyCode <= 57) || (e.keyCode >= 96 && e.keyCode <= 105)) { 
    // 0-9 only
}
