How can I modify this integer validation function to allow for commas and spaces to be entered during the keydown event?
function intValidate(event) {
if (event.keyCode == 46 || event.keyCode == 8 || event.keyCode == 9 || event.keyCode == 27 || event.keyCode == 13 || (event.keyCode == 65 && event.ctrlKey === true) || (event.keyCode >= 35 && event.keyCode <= 39)) {
return;
} else {
if (event.shiftKey || ((event.keyCode < 48 || event.keyCode > 57) && (event.keyCode < 96 || event.keyCode > 105) && event.keyCode < 188)) {
event.preventDefault();
}
}
}
