JS:
// Skrypt 4.2 - shopping.js
// Skrypt wylicza łączną kowtę do zapłaty.

// Funkcja wywoływana w momencie wysyłania formularza.
// Funkcja przeprowadza obliczenia i zwraca wartość false.
function calculate() {
'use strict';

// Umożliwia zapamiętanie łącznej kwoty do zapłaty:
var total;

// Pobranie referencji do pól formularza:
var quantity = document.getElementById('quantity').value;
var price = document.getElementById('price').value;
var tax = document.getElementById('tax').value;
var discount = document.getElementById('discount').value;

// Tutaj zostanie dodana walidacja!

// Wylicz początkową cenę łączną:
total = quantity * price;

// ułatw korzystanie z podatku:
tax /= 100;
tax++;

// Powiększ kwotę o podatek:
total *= tax;

// Uwzględnij rabat:
total -= discount;

// Wyświetl wyliczoną wartość łączną:
document.getElementById('total').value = total;

// Zwróć wartość false, by nie wysyłać formularza:
return false;

} // Koniec funkcji calculate().

// Funkcja wykonywana po zakończeniu wczytywania strony WWW.
// Funkcja dodaje procedurę obsługi zdarzenia do formularza.
function init() {
'use strict';

// Dodaj procedurę obsługi zdarzenia do formularza:
var theForm = document.getElementById('theForm');
theForm.onsubmit = calculate;

} // Koniec funkcji init().

// Przypisz procedurę obsługi zdarzenia do okna przeglądarki:
window.onload = init;
