网课比较麻烦，但是也比较容易，仅仅需要几段代码就可以实现自动刷课。由于本人初学爬虫，对于JavaScript也不是太熟悉，因此在网上找了一些代码，对其进行一下汇总。
打开浏览器，在智慧树网课播放界面按F12 在第二个Console界面复制下面的任意一段代码按enter就可以了，挂着就能自动刷了。
代码一：
写在前面，改代码可以实现1.5倍速播放，静音播放，自动播放下一集，但是不能跳过弹出的习题
(function () {
const MAX_DELAY = 60 // 切课时的最大延迟，单位：秒
const sleep = (time) => new Promise((resolve) => setTimeout(resolve, time))
const start = async function () {
console.log('智慧树助手已启动')
while (true) {
console.log('正在检查')
const delay = Math.floor(Math.random() * MAX_DELAY * 1000) + 1000
if (!/1.5/.test($('.speedBox').attr('style'))) {
console.log('提升到1.5倍速')
$('.speedTab15').click()
}
if (!/liuchang/.test($('.definiBox').attr('style'))) {
console.log('更改画质')
$('.line1bq').click()
}
if ($('.volumeBox').find('.passVolume').width() != 0) {
console.log('静音')
$('.volumeIcon').click()
}
if ($('.playButton').length > 0) {
console.log('点击播放')
$('.playButton').click()
}
if ($('.popbtn_cancel')[0]) {
console.log('发现弹题，将在' + delay / 1000 + ' 秒后点击关闭')
await sleep(delay)
$('.popbtn_cancel').click()
}
if ($('.current_play').find('.progressbar').width() == $('.current_play').find('.progressbar_box').width()) {
console.log('本节完成，' + delay / 1000 + ' 秒后将切到下一课')
await sleep(delay)
$('.current_play').nextAll('.video')[0].click()
}
await sleep(1000)
}
}
start()
}())
代码二：
写在前面，改代码可以实现1.5倍速播放，静音播放，自动播放下一集，并且可以自动跳过习题。
var ti = $("body");
var video = $(".catalogue_ul1 li[id*=video-]");
var i = 1;
var v = 1;
video.css("color", "blue");
console.log("已选取" + video.length + "个小节,并已用蓝色标明,请检查是否有遗漏,如有遗漏,概不负责");
setTimeout(function () {
$('.speedTab15').click();
$('.volumeIcon').click();
console.log("已进行静音和1.5倍加速");
}, 3000);
ti.on("DOMNodeInserted", function (e) {
if (e.target.textContent == "关闭") {
console.log("检测到第" + i + "个弹题窗口");
window.setTimeout(function () {
document.getElementById("tmDialog_iframe").contentWindow.document.getElementsByClassName("answerOption")[0].getElementsByTagName("input")[0].click();
$(".popbtn_cancel").click();
console.log("已关闭");
}, 3000);
i++;
} else if (e.target.textContent == "本节视频,累计观看时间『100%』") {
console.log("检测到视频观看完成，准备跳到下一节");
$('.next_lesson_bg').find('a').trigger('click');
console.log("已跳转");
setTimeout(function () {
$('.volumeIcon').click();
$('.speedTab15').click();
console.log("已进行静音和1.5倍加速");
}, 6000);
v++;
console.log("目前播放了" + v + "个视频");
}
});
代码三：
写在前面，改代码可以实现1.5倍速播放，不能静音播放，自动播放下一集，并且可以自动跳过习题。
