This only works in google chrome:
这仅适用于谷歌浏览器：
<input type="file" webkitdirectory>
This will prompt the user to select a directory and you can then access the filesproperty of the input to see the contained files.
这将提示用户选择一个目录，然后您可以访问files输入的属性以查看包含的文件。
It is then possible to use the File System APIto construct a virtual, sandboxed file system of the user selected files and have programmatic access to this virtual filesystem as if it was a real filesystem accessed by desktop app.
然后可以使用文件系统 API为用户选择的文件构建一个虚拟的沙盒文件系统，并对该虚拟文件系统进行编程访问，就好像它是桌面应用程序访问的真实文件系统一样。
There is no way otherwise because that would be a big security issue
没有别的办法，因为那将是一个很大的安全问题

Javascript/Jquery does not have access to the local file system for security reasons. This is not possible.So try some server side base code.
出于安全原因，Javascript/Jquery 无权访问本地文件系统。这是不可能的。所以尝试一些服务器端基本代码。

Now, some years later, accessing to local filesworks fine in Chrome ANDFirefox (52.8, but update Firefox is easy). It works also with IE 11.
现在，几年后，在 Chrome和Firefox 中访问本地文件可以正常工作（52.8，但更新 Firefox 很容易）。它也适用于 IE 11。

You could write a script using a technology like php, ruby, java which will list all files and then send this information via ajax to Your browser.
您可以使用 php、ruby、java 等技术编写脚本，该脚本将列出所有文件，然后通过 ajax 将此信息发送到您的浏览器。
But You can't do this only via javascript because of security restrictions.
但是由于安全限制，您不能仅通过 javascript 执行此操作。

I don't think this is possible because accessing the local file system is a terrible security risk.
我认为这是不可能的，因为访问本地文件系统是一个可怕的安全风险。

Javascript can't access the users drive. That would be a big security issue, wouldn't it? :D
Javascript 无法访问用户驱动器。那将是一个很大的安全问题，不是吗？:D
Instead, you need to use an other technology like flash or java-applets.
相反，您需要使用其他技术，如 flash 或 java-applet。

it is not possible to have javascript-access to the local file-system from the browser, and this is good so!
不可能从浏览器对本地文件系统进行 javascript 访问，这很好！
