代码如下:
public class FileInformation
{
public string FullPath
{
get; set;
}
public string Name
{
get; set;
}
public string Info
{
get; set;
}
public bool IsFolder
{
get; set;
}
} 代码如下:
public class FileManager
{
public static List<FileInformation> GetFolderContent(string fullpath)
{
List<FileInformation> res = new List<FileInformation>();
DirectoryInfo info = new DirectoryInfo(fullpath);
if (info.Exists)
{
foreach (DirectoryInfo d in info.GetDirectories())
{
res.Add(new FileInformation
{
FullPath = d.FullName, Name = d.Name,IsFolder = true,
Info = "Any More Information goes here"
});
}
foreach (FileInfo f in info.GetFiles())
{
res.Add(new FileInformation
{
FullPath = f.FullName,Name = f.Name,IsFolder = false,
Info = "Any More Information goes here"
});
}
}
return res;
}
} 代码如下:
public static string ToJson<T>(T obj)
{
DataContractJsonSerializer d = new DataContractJsonSerializer(typeof(T));
System.IO.MemoryStream ms = new System.IO.MemoryStream();
d.WriteObject(ms, obj);
string strJSON = System.Text.Encoding.UTF8.GetString(ms.ToArray());
ms.Close();
return strJSON;
} 代码如下:
public class FileList : IHttpHandler {
public void ProcessRequest (HttpContext context) {
string path = context.Request.QueryString["path"];
string data = JsonHelper.ToJson<List<FileInformation>>(FileManager.GetFolderContent(path));
context.Response.Write(data);
}
public bool IsReusable {
get {
return false;
}
}
} 代码如下:
<body> <ul> </ul> </body>
代码如下:
$(function() {
$('<li class="folder">D:\\<span class="fullpath">D:\\</span></li>').appendTo('ul');
$('li').hover(function() {
$(this).css('cursor', 'pointer');
},
function() { $(this).css('cursor', 'default'); });
$('li.folder').toggle(LoadFile, CloseFolder);
}); 代码如下:
function LoadFile(event) {
if (this == event.target) {
var path = $(this).find('span').html();
var node = $('<ul>');
$(this).append(node);
$.getJSON('filelist.ashx', { path: path }, function(data) {
$.each(data, function() {
if (this.IsFolder) {
node.append($('<li>').addClass('folder').html(this.Name).append($('<span>').addClass('fullpath').html(this.FullPath)));
}
else {
node.append($('<li>').addClass('file').html(this.Name).append($('<span>').addClass('fullpath').html(this.FullPath)));
}
});
node.find('li.folder').toggle(LoadFile, CloseFolder);
});
}
} 代码如下:
function CloseFolder(event) {
if (this == event.target)
$(this).find('ul').remove();
} 代码如下:
function CloseFolder(event) {
if (this == event.target) {
var node = $(this).find('ul');
node.hide('slow', function() { $(this).find('ul').remove(); });
}
} 结束数据方法的参数,该如何定义?-- 集合为自定义实体类中的结合属性,有几个实体类,改变下标就行了。<input id="add" type="button" value="新增visitor&quo
本文实例讲述了php+ ajax 实现的写入数据库操作。分享给大家供大家参考,具体如下:。<input class="tel" type="text" placeholder="请输入您的手机号码&q
