and I have cuple of js files but for this problem just 2 was importanr my server.js

const express = require('express');
const bodyParser = require('body-parser');
const nodemailer = require('nodemailer');
const path = require('path');
require('dotenv').config(); // Učitaj .env datoteku

const app = express();
const port = 3000;

app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

// Serve static files from the root directory
app.use(express.static(path.join(__dirname)));

// Serve the 'checkout.html' file as the default page
app.get('/', (req, res) => {
    res.sendFile(path.join(__dirname, 'checkout.html'));
});

// Endpoint to handle form submission
app.post('/send-email', (req, res) => {
    const { name, phone, address, country, city, companyName, contactName, list, totalPrice } = req.body;

    const currentDateTime = new Date().toLocaleString();

    // Extract product names and quantities from the list
    const productList = JSON.parse(list).map(item => `${item.name} (Kolicina: ${item.quantity})`).join('n');

    // Create a transporter
    const transporter = nodemailer.createTransport({
        service: 'gmail', // Use your email provider
        auth: {
            user: process.env.EMAIL_USER, // Your email address from .env
            pass: process.env.EMAIL_PASS // Your email password from .env
        }
    });

    // Email options
    const mailOptions = {
        from: 'Sajt',
        to: '[email protected]', // Change this to your recipient email address
        subject: 'New Order',
        text: `Name: ${name || companyName}nPhone: ${phone}nAddress: ${address}nCountry: ${country}nCity: ${city}nContact Name: ${contactName || ''}nDate and Time: ${currentDateTime}nnOrder Details:n${productList}nnTotal Price: ${totalPrice}`
    };

    // Send email
    transporter.sendMail(mailOptions, (error, info) => {
        if (error) {
            console.log(error);
            res.status(500).send('Error sending email');
        } else {
            console.log('Email sent: ' + info.response);
            res.status(200).send('success');
        }
    });
});

app.listen(port, () => {
    console.log(`Server running at http://localhost:${port}/`);
});

and my checkout1.js file

document.querySelectorAll('.form').forEach(form => {
    form.addEventListener('submit', function(e) {
        e.preventDefault();

        // Prvo proveri da li je reCAPTCHA potvrđena
        let captchaResponse = form.querySelector('.g-recaptcha-response').value;

        if (!captchaResponse) {
            alert('Molimo vas da potvrdite da niste robot.');
            return;
        }

        // Prikupi podatke iz forme
        let formData = {};
        new FormData(form).forEach((value, key) => {
            formData[key] = value;
        });
        formData['g-recaptcha-response'] = captchaResponse;

        // Podesi list i totalPrice u zavisnosti od forme
        let listName = form.querySelector('input[name="list"]');
        let totalPriceName = form.querySelector('input[name="totalPrice"]');

        if (listName && totalPriceName) {
            let listCart = JSON.parse(localStorage.getItem('listCart')) || [];
            let totalPrice = calculateTotalPrice(listCart);

            listName.value = JSON.stringify(listCart);
            totalPriceName.value = totalPrice;
        }

        // Kreiraj AJAX zahtev
        let xhr = new XMLHttpRequest();
        xhr.open('POST', '/send-email');
        xhr.setRequestHeader('Content-Type', 'application/json');
        xhr.onreadystatechange = function() {
            if (xhr.readyState == XMLHttpRequest.DONE) {
                if (xhr.status == 200) {
                    // Resetuj korpu i preusmeri na index.html
                    resetCart();
                    window.location.href = '/index.html';
                } else {
                    alert('Došlo je do greške prilikom slanja podataka. Molimo pokušajte ponovo.');
                }
            }
        };
        xhr.send(JSON.stringify(formData));
    });
});

// Funkcija za izračunavanje ukupne cene (primer, implementirajte prema vašim potrebama)
function calculateTotalPrice(listCart) {
    return listCart.reduce((total, item) => total + item.price * item.quantity, 0);
}

// Funkcija za resetovanje korpe
function resetCart() {
    localStorage.removeItem('listCart'); // Uklanja podatke iz localStorage
    listCart = []; // Prazni niz listCart

    // Ažurira HTML da odražava praznu korpu
    addCartToHTML();
}

<input type="hidden" name="totalPrice" id="totalPrice1">
