帮朋友刷课，网页版视频课，不能拖动进度条，要刷 90 个学时，太尼玛变态了，所以想到刷课。
以前类似的需求我都是通过抓包工具 BurpSuite 改观看时长变量，然后放包实现的，也屡试不爽。但这次发现并不好使。。放包之后去课程页面看了，没有任何效果。看了源码也并没有研究清楚是哪里限制了，我都是按照 POST 数据的合法性放包的。
用扩展加速视频，发现也不好使，应该也是 js 禁止了视频加速
看了下网页源码发现是 js 控制禁用了许多功能，看来只有自己写 js 脚本 override 原有脚本了，可惜我 js 并不熟。前端大佬们帮忙看下，提供个思路。谢谢啦，我把源码贴出来，关键的地方应该也就是那几个。辛苦辛苦师傅们
