Hexo Butterfly博客魔改的一点点基础

很久以前，Dorakika自己做了一个不错的右键菜单，借鉴于Volantis主题，当然我是在洪哥的博客里面看到的。

引用站外地址，不保证站点的可用性和安全性
自定义右键菜单
Dorakika

然后我就给它做了一些小改进，并且分享给大家。

我做了什么？

2022.9.17更新：

在MrZeFr的建议下，增加了ctrl显示原版功能。

1660699020974.webp

1660699034686.webp

原版的菜单只有昼夜切换、阅读模式、主题切换、复制、其它设置和一些基础的浏览器功能，我添加了这些功能：

  1. 粘贴功能
    1660699109204.webp
  2. 空降评论、随便逛逛、繁简转换、版权声明功能（分享已删）

1660699153037.webp

  1. 复制文章地址功能

1660699573998.webp

  1. 图片方面的一些功能

1660699615891.webp

  1. 对于a标签的打开功能

1660699665936.webp

  1. 百度搜索文本和转到链接功能

1660700020712.webp

  1. 兼容dorakika的评论弹幕功能

1660700055672.webp

  1. Ctrl唤出原版右键菜单

1663414955319.png

并且换用了font awesome图标，除了百度和繁简转换的logo需要你下载iconfont图标库，也会放出教程

如何修改？

下面放出魔改教程，使用我修改过的pug和js进行魔改，参照自dorakika的原版。

因为这个js依赖于jquery，所以还需要引入jquery，在主题配置文件中引入：

1

8
inject:
  head:
  - ...
  bottom:
  - ...
  - <script type="text/javascript" src="https://cdn1.tianli0.top/npm/jquery@latest/dist/jquery.min.js"></script>
  - <script type="text/javascript" src="/js/rightmenu.js"></script>
  - ...

然后你就拥有了一个好看且功能丰富的右键菜单了！
