PHP开发实现下载次数统计完整实现代码

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>

<style type="text/css">

              });
            $(".filelist").html(li);
         }
      }
   });
   $('ul.filelist a').live('click',function(){
