## 1. 十倍速＆自動點掉下個課程
``` javascript
// 十倍速
setInterval(() => {
let player = document.getElementById("aplayer");
if (player && player.playbackRate !== 10.0) {
player.playbackRate = 10.0;
}
}, 1000); // 每秒檢查一次
// 自動點
window.confirm = function() {
console.log("偵測到 confirm，已自動點擊 '確定'");
return true;
};
```
## 2. 測驗答題 - 半自動版
#### 1. 複製題目丟給chatGPT
``` javascript
= = = = = = = = = = = =
[題目貼在這裡]
= = = = = = = = = = = =
幫我作答以上題目 答案化為這種形式
// 是非題的答案索引（0 = 對，1 = 錯）
const ynAnswers = [x,x];
// 單選題的答案索引
const singleAnswers = [x,x];
// 複選題的答案索引
const doubleAnswers = [
[x,x],
[x],
];
```
#### 2. 得到的回應 與下面組合 貼在 console 裡面
``` javascript
= = = = = = = = = = = = = = = =
[ 得到的回應貼在這裡 ]
= = = = = = = = = = = = = = = =
// 點是非題
ynAnswers.forEach((ans, i) => {
const id = `ctl00_ContentPlaceHolder1_gvYN_ctl${String(i + 2).padStart(2, '0')}_rbYorN_${ans}`;
const el = document.getElementById(id);
if (el) el.click();
});
// 點單選題
singleAnswers.forEach((ans, i) => {
const id = `ctl00_ContentPlaceHolder1_gvSingle_ctl${String(i + 2).padStart(2, '0')}_rbSingle_${ans}`;
const el = document.getElementById(id);
if (el) el.click();
});
// 點複選題
doubleAnswers.forEach((answers, i) => {
answers.forEach(ans => {
const id = `ctl00_ContentPlaceHolder1_gvDouble_ctl${String(i + 2).padStart(2, '0')}_rbDouble_${ans}`;
const el = document.getElementById(id);
