有些网站（例如起点等）为了版权问题而禁用了右键复制的功能，甚至替换了右键菜单（例如起点），这个脚本的作用就是为了重新恢复禁用的复制功能（当然可以扩展其它功能，比如恢复右键菜单）。这个脚本的初衷是，我在准备驾校理论考的时候，在tieba.jxydt.com查找信息并且做笔记的时候，却发现该网站禁用了复制功能，那时候非常无奈，就开始动手写这个脚本，后来为了考虑一些扩展性，添加、封装了一些代码。
总体来说，这个脚本的扩展性还是可以的。可以非常方便的添加更多需要恢复复制功能的网站，但是我个人不是非常满意，觉得有些地方代码有点臃肿了。当然后期的进一步完善，还是需要更多朋友提供建议和反馈。脚本目前支持Firefox和Chrome，其它浏览器未测试。
最新版的代码可以在UserScripts.org下载：地址。
原理很简单，无非是找到相关的页面元素，删除或者替换与复制相关的事件，例如oncopy/onselectstart/oncontextmenu/onmousedown等等。如果有一点JavaScript代码的基础，可以参考脚本中已有的网站支持的代码添加新站点支持。不然你可以在这里留言，我会帮你添加。
支持的网站：
- Qidian.com和Qdmm.com
- 360doc.com
- jxydt.com
- tieba.baidu.com
