本脚本和Chrome扩展插件适用于超星尔雅慕课(即观看视频网页地址满足 *://*.chaoxing.com/mycourse/* )(*表示省略）,若你的课程平台是智慧树，或者不会使用脚本，请参考这篇文章。
参考Github上的这个项目，我也配置了智慧树课程助手脚本和Chrome扩展插件。
优势：操作简单，无需安装配套软件，可视进度，安全;
开启时只需点击按钮。如果想停止本脚本请刷新页面。
同时，你也可以通过Chrome扩展程序开发者模式加载已解压的扩展程序，将本文件夹下载到本地进行加载。
如果你觉得验证码或视频中的弹题很讨厌，请尝试也建议向兼容 AdBlock Plus 语法的广告过滤扩展添加这条自定义规则：
*.chaoxing.com/richvideo/initdatawithviewer*
支持 课程自动切换，自动静音播放（默认静音），播放线路切换（需手动配置参数）;
若想要更多功能，如 **自动答题，5秒内一节课 **（都是高危不良行为），切换画质 的，请参考这里（脚本未测试，似乎已失效）;
建议在一些微信公众号如：小马搜题订阅号，问答库，殿下网络互联 等的帮助下，题目自己手动做；
已知问题：已经显示完成的视频再次播放或自动播放的过程中手动进行跳转视频的操作将无法自动切换线路。且切换线路不够智能，只能切换到最后一个线路。
建议在谷歌浏览器下F12进入开发者模式，然后切换到console，在视频已经加载的前提下，首先输入以下命令：
let playline = $("iframe").contents().find("iframe").contents().find("li.vjs-menu-item.vjs-selected");然后将下面命令的变量i从0递增，进行尝试，当看到显示了线路名称，记下i，并对脚本对应的地方进行修改：
playline[1].nextElementSibling.click();如果不想切换线路，则可以将切换线路和防止切换线路多次不成功导致的问题注释包括的部分进行清理，并一并清理变量errors和n;
默认的自动跳转课程方法适用于绝大部分课程的自动播放，但是也有一些课程会遇上问题，具体表现为只自动跳转播放相应章的第一节，遇到这种情况时，我们需要针对这种特殊课程更改“跳转到下一课”注释下的全部内容为以下代码：
//跳转到下一课 Jump to the next course
try {
tmp = $("h4.currents")[0].parentElement.nextElementSibling.children[0];
}
catch (err) {
try {
tmp = $("h4.currents")[0].parentElement.parentElement.nextElementSibling.children[0];
}
catch (err) {$("h4.currents")[0].parentElement.parentElement.nextElementSibling.children[0];}
}
if (tmp.hasAttribute('href')) {
if (tmp.href != "javascript:void") {
tmp.children[0].click();
}
}
else {
try {
tmp = tmp.parentElement;
}
catch (err) {
tmp = tmp.parentElement.children[1].children[0];
}
if (tmp.href != "javascript:void") {
tmp.children[0].click();
}
}因为时间有限，所以脚本做得有些简单，很有可能不太稳定，欢迎大家进行完善。
因为中国互联网审查机制，本人不能将此插件上传至Chrome应用商店，因此我在此授权，在通知本人的情况下，欢迎有能力的人将此插件发布在Chrome应用商店上。
最新测试时间：2019年9月12日，不能保证脚本在此之后一直有效；
The script and Chrome extension plug-ins are suitable for ChaoXing Erya MOOC (i.e. web address meets *://.chaoxing.com/mycourse/*)( denotes ellipsis). If your course platform is Wisdom Tree or you don't know how to use scripts, please refer to this article(Chinese Version).
Referring to that Repository on the Github, I also configure Wisdom-Tree-Lessons-Helper Script and Chrome extension plug-ins.
Advantages: simple operation, no need to install supporting software, visual progress, safety;
Just click the button when you open it. Refresh the page if you want to stop.
At the same time, you can also download this folder locally and using the plugin by add it to Chrome Extension Program Developer Mode Loading the decompressed Extension Program.
If you find the the authentication code or questions block you from playing video annoying, try and recommend adding this custom rule to the AdBlock Plus grammar-compatible ad filtering extension as well:
*.chaoxing.com/richvideo/initdatawithviewer*
Support automatic course switching, automatic silent playback (default silence), play line switching (manual configuration of parameters);
If you want more functions, such as automatic doing quizs, a lesson done in 5 seconds (all high-risk bad behavior) and quality switching, please refer to here(scripts are not tested by me and seem to be invalid)(Chinese Version);
It is suggested that with the help of some Wechat public accounts such as 小马搜题订阅号，问答库，殿下网络互联 , the questions after each lesson should be done by yourself.
Known problem: The manual operation of jumping video in the process of replaying or playing the completed video will not automatically switch the Play line. Moreover, the playline-switching function is not smart enough, and can only switch to the last line.
It is recommended that F12 enter developer mode under Chrome, then switch to console. On the premise that the video has been loaded, first enter the following commands:
let playline = $("iframe").contents().find("iframe").contents().find("li.vjs-menu-item.vjs-selected");Then increase the variable i of the following command from 0 to try. When you see the line name displayed, remenber the value of i and modify the corresponding place of the script:
playline[1].nextElementSibling.click();If you don't want to switch lines, you can clean up the parts included in the notes Switching lines and Preventing problems caused by multiple unsuccessful switching lines, and clean up the variables errors and n together.
The default method of automatic jump course is applicable to most courses, but there are also some courses that will encounter problems, such as only automatically jump to play the first section of the corresponding chapter. In this case, we need to change the whole content of the "Jump to the next course" annotation for this special course as follows The following code:
//跳转到下一课 Jump to the next course
try {
tmp = $("h4.currents")[0].parentElement.nextElementSibling.children[0];
}
catch (err) {
try {
tmp = $("h4.currents")[0].parentElement.parentElement.nextElementSibling.children[0];
}
catch (err) {$("h4.currents")[0].parentElement.parentElement.nextElementSibling.children[0];}
}
if (tmp.hasAttribute('href')) {
if (tmp.href != "javascript:void") {
tmp.children[0].click();
}
}
else {
try {
tmp = tmp.parentElement;
}
catch (err) {
tmp = tmp.parentElement.children[1].children[0];
}
if (tmp.href != "javascript:void") {
tmp.children[0].click();
}
}Statement: I will not bear any responsibility for the adverse consequences of using this script in any improper way.
Because of the limited time, the script is a little simple and probably not stable. Modifying and improving it is welcomed.
Because of the Internet blocks in China, I can not upload this plug-in to the Chrome App Store, so I authorize you to publish the plug-in to the Chrome App Store if you have the ability to access Google App Store and inform me in advance.
Latest Test time: September 12, 2019, can not guarantee that the script will be always valid after the date;
