乐课网助手

用于快速完成乐课网录播课学习任务

安装

1. 桌面设备或Android手机可以安装用户脚本管理器Tampermonkey篡改猴或其他插件如油猴
2. iOS 可以使用via Userscripts for Safari gear Alook等支持用户脚本的Browsers或插件
3. Android 可以使用via等支持用户脚本的Browsers
4. 更多支持的程序可以在Greasy Fork查看，同时也提供安装教程
5. 由于一些限制，暂时没有在Greasy Fork上发布
6. 使用控制台无需安装
7. 安装此用户脚本 (此版本仅使用于桌面设备)
8. 同时适用于桌面设备和移动设备的版本支持自动提交，无需手动操作，播放页面加载完成后等待2秒即可
9. 调速脚本 (仅推荐脚本，并非原作者)

使用方法

选择用户脚本管理器右键菜单中快速完成课程选项即可

或者在播放界面打开开发人员工具>控制台复制并粘贴下面的链接内的内容(也适用于移动设备)
