 学习通刷课太痛苦？试试这个Js脚本

/** * 本脚本用于学习通自动刷课,仅做学习用途 * 转发请注明作者以及来源 *//**定义全局变量 */var array_echelon;//顺序执行梯队/**定义事件 */let dealEvent = new Event("redeal", { bubbles: false, cancelable: false });/**监听事件 */document.addEventListener("redeal", function () {    dealAnsEchelon(array_echelon);});/**初始化 */function initAll() {    console.log("获取当前页面任务中···");

代码基本都给了注释，目前没发现Bug
