获取目录中所有文件夹的列表 [英] get a list of all folders in directory

问题描述

所以我有一个如下所示的文件系统：

 音乐
  -  001 
  -  -  song.mp3 
  -  002 
  -  song.mp3 
  -  003 
  -  004 
  -  005 
  -  song.mp3 
 musicplayer.html 
 musicplayer.js 
  

我很好奇是否有可能获得列表关于所有的文件夹名称？

这个javascript，html5甚至jQuery，我不能安装任何东西。

只是没有，但不是最后的答案！ JavaScript（JS）是一种解释性的计算机编程语言。它最初是作为Web浏览器的一部分实现的，因此客户端脚本可以与用户进行交互，控制浏览器，异步通信以及更改显示的文档内容。

有三种主要的JavaScript类型：

 客户端JavaScript（CSJS） -  JavaScript的扩展版本，可以增强和处理网页和客户端浏览器
 
服务器端JavaScript（SSJS） - 支持后端访问数据库，文件系统和服务器的JavaScript扩展版本
 
核心JavaScript  - 基本JavaScript语言
  

客户端JavaScript（CSJS）和服务器端JavaScript（SSJS）分别是依赖核心JavaScript，不能没有它。

JavaScript和DOM为恶意作者提供脚本以通过网络在客户端计算机上运行的潜力。浏览器作者使用两个限制包含这种风险。首先，脚本在沙箱中运行，其中只能执行与网络相关的操作， 不是通用编程任务，如创建文件 。其次，脚本受同一起源策略的约束：来自一个网站的脚本无法访问诸如用户名，密码或发送到其他站点的cookie等信息。大多数与JavaScript相关的安全漏洞都违反了相同的原始策略或沙箱。

有一般JavaScript的子集 - ADsafe，安全ECMA脚本（SES） - 提供更高级别的安全性，特别是第三方创建的代码（如广告）。

我很好奇是否有可能获得关于所有文件夹
名称的列表？与HTML5

HTML5提供了FileSystem API，可以解决您的口渴，至少知道：） >

另一个解决方案是使用丑陋的浏览器Api，我永远不会推荐
< br> 最佳解决方案 是使用服务器端语言，如php

So I have a file system that looks like this:

Music
- 001
-- song.mp3
- 002
-- song.mp3
- 003
- 004
- 005
-- song.mp3
musicplayer.html
musicplayer.js

I was curious if it is possible to get a list about all of the folders names?

This javascript, html5, or even jQuery, I can not install anything.

he has a point in his question (HTML5)

Simply No , but not the Last Answer !

JavaScript (JS) is an interpreted computer programming language.It was originally implemented as part of web browsers so that client-side scripts could interact with the user, control the browser, communicate asynchronously, and alter the document content that was displayed.

There are 3 major types of JavaScript namely:

Client-Side JavaScript (CSJS) -- an extended version of JavaScript that enables the enhancement and manipulation of web pages and client browsers

Server-Side JavaScript (SSJS) -- an extended version of JavaScript that enables back-end access to databases, file systems, and servers

Core JavaScript -- the base JavaScript language

Client-Side JavaScript (CSJS) and Server-Side JavaScript (SSJS) are dependent on the core JavaScript and cannot work without it.

JavaScript and the DOM provide the potential for malicious authors to deliver scripts to run on a client computer via the web. Browser authors contain this risk using two restrictions. First, scripts run in a sandbox in which they can only perform web-related actions, not general-purpose programming tasks like creating files. Second, scripts are constrained by the same origin policy: scripts from one web site do not have access to information such as usernames, passwords, or cookies sent to another site. Most JavaScript-related security bugs are breaches of either the same origin policy or the sandbox.

There are subsets of general JavaScript — ADsafe, Secure ECMA Script (SES) — that provide greater level of security, especially on code created by third parties (such as advertisements).

I was curious if it is possible to get a list about all of the folders names? with HTML5

HTML5 provides FileSystem API which may solve your thirst , at least for know :)
Read the tutorial here : http://www.html5rocks.com/en/tutorials/file/filesystem/

another solution is to use the ugly browser Api, that i never ever recommends
Best Solution is to use a server side language like php
