Kami mencipta fail pangkalan data conn.php dalam bab sebelumnya, baca pangkalan data dan panggil fail filelist.php dan fail muat turun.php yang digunakan untuk membalas muat turun
Dalam bahagian ini kami akan memaparkan sepenuhnya halaman hadapan, menambah fail jQuery dan AJAX asynchronous index.html.
Di sini kami telah memperkenalkan pautan perpustakaan awam jQuery
<script type="text/javascript" src="//cdn.bootcss.com/jquery/1.10.1/jquery.min.js"></script>
Berikut ialah kod lengkap index.html:
<!DOCTYPE HTML>

<meta charset="utf-8">
