思源笔记 查看代码片段 插件

JS

提示：我不懂做插件，不知道怎么让添加的顶栏按钮持续显示，所以每当你开启一次插件就会添加一个按钮，并且重启思源笔记软件后添加的按钮会消失。因此这个插件的作用只是演示代码的作用，如果需要的话请复制下面的 JS 代码，然后添加到 JS 代码片段中。

如果你有能力且愿意帮助我完善插件，请修改代码后向 代码仓库 提交 Pull Requests 或提出 Issue 。

/**
 * 在顶栏添加按钮，快捷打开代码片段界面 JS片段 https://github.com/TCOTC/siyuan-js-open-snippets-dialog
 * 参考 https://ld246.com/article/1674026309504 修改，同时感谢 [Undii](https://ld246.com/member/Undii) 提供 帮助
 * 为顶栏增加代码片段按钮，点击后创建快捷键按下事件
 * 挂件模式支持点击日记列出笔记本。 https://ld246.com/article/1674026309504
