<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>文件管理</title>
<script src="bootstrap/js/jquery-1.11.2.min.js"></script>
</head>
<style>
*{ margin:0px auto; padding:0px} #wai{ width:800px;}
.list{ width:50%; height:35px; background-color:#09F; margin-top:2px; color:white; font-weight:bold; text-align:left; line-height:35px; vertical-align:middle; font-size:28px; padding:5px}
.mulu{ background-color:#FC9}
.mulu:hover{ cursor:pointer}
#prev:hover{ cursor:pointer}
</style>
<body>
<p id="outside">
<?php
session_start();
$fname = "/wamp/www";//使$filename的值为根文件夹中www目录下的所有文件夹
if(!empty($_SESSION["lujing"])){
$fname = $_SESSION["lujing"];//把session存储的路径赋值给$fname
echo "<p id='prev' class='list' lj='{sj}'>返回上一级</p>";
}
?>
<p id="inside">
<?php
$sj = dirname($fname);
$dir = opendir($fname);
$arr = array();//将文件夹与文件合并放入
$arr1 = array();//放入文件夹
$arr2 = array();//放入文件
while($filename = readdir($dir)){//把$fname里面的所有内容遍历出来
if($filename != "."){
$ml = $fname."/".$filename;
if(is_dir($ml)){
$arr1[ ] = $ml;
}else{
$arr2[ ] = $ml;
}
}
}
$arr = array_merge($arr1,$arr2);
foreach($arr as $v){
$filename = basename($v);
if(is_dir($v)){
echo "<p lj='{$ml}' class='list mulu'>{$filename}</p>";
}else{
echo "<p class='list'>{$filename}</p>";
}
}
closedir($dir);
?>
</p>
</p>
</body>
<script>
$(".mulu").dblclick(function(){
var lj = $(this).attr("lj");//取点击内容自己的属性值lj，lj里面存储的是点击的文件夹的目录
$.ajax({
url:"file_zip_chuli.php",
data:{lj:lj},
type:"POST",
dataType:"TEXT",
success:function(){
window.location.href = "file_zip.php";
