JavaScript是一门客户端的脚本语言,但是你千万不要认为它功能弱哦,因为你看了下面的例子之后就明白了。
一. 用JavaScript写的操作系统
呵呵,那天同事开玩笑说,要是有个用JS写的操作系统就好了. 我们都笑他异想天开,想不到的是,竟然真的有用JavaScript写的操作系统:JS/UIX。它的网址是:http://www.masswerk.at/jsuix/。
* 系统介绍
它的首页上是这么说的:JS/UIX 是一个基于Web浏览器的类Unix操作系统,没有使用任何插件技术,完全采用Javascript编写。它包含一个虚拟机、一个shell、虚拟文件系统、进程管理、屏幕终端以及键盘映射。它兼容Netscapge、IE 4以上等浏览器。
英文介绍:
JS/UIX is an UN*X-like OS for standard web-browsers, written entirely in JavaScript (no plug-ins used). It comprises a vir-tual machine, shell, virtual file-system, process-management,and brings its own terminal with screen- and keyboard-mapping.
The keyboard accepts the US-ASCII character set.As key-mapping depends from your browser, you may have to use the cursor and backspace buttons at the lower right of the terminal. A complete keyboard can be accessed at the lower left.
Compatibility: Netscape 4+, MS IE 4+ and DOM-aware browsers.
该系统文档也很完善,有一个支持的命令手册:http://www.masswerk.at/jsuix/man.txt,和一个版本历史记录。我测试过它支持Firxfox和IE,看来功能比较强大呀。
* 如何使用
打开在上面的网址,在页面顶端打开“> open terminal ”链接,那么将出现如下面的一个登陆提示框:
JS/UIX 0.45 starting up [init] ... terminal (dhtml-gui) ready. bringing up the file-system ... ok re-entering file-system as root. building tree ... ok trying for RC-file ... found rc-profile looks good. initializing rc-profile ... ok re-entering tree for command-system ... ok setting up system variables ... ok system up and stable. starting login-demon. JS/UIX:Log-on - type user-name (e.g. "guest") and hit <return>. login: 在login中输入guest,回车就可以登陆了。进去以后就能够看到下面的提示:
Terminal ready. JS/UIX 0.45 - The JavaScript virtual OS and terminal application for the web. Type "info" for site information. Type "help" for available commands. ------------------------------------------------------------------------------ [guest@www.masswerk.at:2]$ & [1] [2] 下一页 没有相关教程
