Bahagian ini menunjukkan kod lengkap fungsi troli beli-belah yang dibangunkan oleh JavaScript.
Dengan merujuk 4 fail JS yang kami cipta, semua fungsi troli beli-belah dilaksanakan sepenuhnya pada halaman.
Kami mencipta fail list.php untuk paparan produk, fail cookie.js mengendalikan kuki,
fail index.js mengendalikan halaman senarai, pelayan .js mengendalikan modul data tempatan.
Fail cart.php memaparkan halaman troli beli-belah dan fail cart.js mengendalikan troli beli-belah.
