前面章节我们创建了conn.php数据库文件,读取数据库并调用的filelist.php文件和用来响应下载的download.php文件
本节我们将完整的展示前端页面,加入了jQuery和AJAX异步的index.html文件。
这里我们引入了jQuery公共库链接
<script type="text/javascript" src="//cdn.bootcss.com/jquery/1.10.1/jquery.min.js"></script>
下面是index.html的完整代码:
<!DOCTYPE HTML> <html> <head> <meta charset="utf-8"> <title>PHP+Mysql+jQuery实现文件下载次数统计</title> <style type="text/css"> #demo{width:80%;margin:50px auto;padding:10px;border:1px solid #ddd;background-color:#eee;} ul.filelist li{background:url("/upload/course/000/000/008/582e53ad28601855.gif") repeat-x center bottom #F5F5F5; border:1px solid #ddd;border-top-color:#fff;list-style:none;position:relative;} ul.filelist li.load{background:url("/upload/course/000/000/008/582e5313d54a1210.gif") no-repeat; padding-left:20px; border:none; position:relative; left:150px; top:30px; width:200px} ul.filelist li a{display:block;padding:8px;} ul.filelist li a:hover .download{display:block;} span.download{background-color:#64b126;border:1px solid #4e9416;color:white; display:none;font-size:12px;padding:2px 4px;position:absolute;right:8px; text-decoration:none;text-shadow:0 0 1px #315d0d;top:6px; -moz-border-radius:3px;-webkit-border-radius:3px;border-radius:3px;} span.downcount{color:#999;font-size:10px;padding:3px 5px;position:absolute; margin-left:10px;text-decoration:none;} </style> <script type="text/javascript" src="//cdn.bootcss.com/jquery/1.10.1/jquery.min.js"></script> <script type="text/javascript"> $(function(){ $.ajax({ type: 'GET', url: 'filelist.php', dataType: 'json', cache: false, beforeSend: function(){ $(".filelist").html("<li class='load'>正在载入...</li>"); }, success: function(json){ if(json){ var li = ''; $.each(json,function(index,array){ li = li + '<li><a href="download.php?id='+array['id']+'">'+array['file']+'<span class="downcount" title="下载次数">' +array['downloads']+'</span><span class="download">点击下载</span></a></li>'; }); $(".filelist").html(li); } } }); $('ul.filelist a').live('click',function(){ var count = $('.downcount',this); count.text( parseInt(count.text())+1); }); }); </script> </head> <body> <div id="header"> <div id="logo" style="text-align: center"><h2>下载统计</h2></div> </div> <div id="main"> <div id="demo"> <ul class="filelist"> </ul> </div> </div> <div id="footer"> </div> </body> </html>
