郑东新区实验幼儿园 
# 脚本介绍
该油猴脚本用于 郑东新区实验幼儿园教师研修平台 的辅助看课，使用JavaScript编写，适配网址：http://zdxqsyyey.zhihuiteacher.com
脚本功能如下：
1.自动播放课程视频，无需手动操作
2.解除视频暂停限制，持续播放
3.防止页面切出导致学习中断
4.自动检测并处理各种播放限制
5.优化学习体验，提升学习效率

# 安装教程
# 1.安装浏览器扩展插件
首先需要给我们的浏览器安装上脚本猫插件，这是运行所有用户脚本的基础，如果浏览器已经安装过了脚本猫或者油猴插件，那么可以跳过这一步。推荐使用edge浏览器，安装插件更方便。
浏览器打开网址：https://docs.scriptcat.org/ (opens new window)
这里用edge浏览器作为示范，点击 "添加到Edge浏览器"
接着点击 "获取"
在右上角弹出的窗口，点击 "添加扩展"
等待几秒钟，会提示已经安装好脚本猫插件了。
# 2.安装刷课脚本
打开脚本安装地址后，在页面点击 "安装脚本" 按钮，接着在弹出的窗口点击 "安装" ，之后就会提示"安装成功"。
# 3.体验脚本功能
安装脚本后，需要重新进入学习站点，如果之前已经打开课程学习页面，那么需要刷新页面后脚本才会生效。
