jQuery validation to allow only numbers to input:


jQuery("#discountrise_amount").keydown(function (e) {
// Allow: backspace, delete, tab, escape, enter and .
if (jQuery.inArray(e.keyCode, [46, 8, 9, 27, 13, 110, 190]) !== -1 ||
// Allow: Ctrl+A
(e.keyCode == 65 && e.ctrlKey === true) ||
// Allow: home, end, left, right
(e.keyCode >= 35 && e.keyCode <= 39)) { // let it happen, don't do anything return; } // Ensure that it is a number and stop the keypress if ((e.shiftKey || (e.keyCode < 48 || e.keyCode > 57)) && (e.keyCode < 96 || e.keyCode > 105)) {
e.preventDefault();
}
});
