为什么模拟事件没有反应
想写一个自动打字的脚本 www.monkeytype.com!(data/attachment/forum/202202/12/173124hs29903209gjw0s9.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/300 "image.png")
我想模拟键盘的输入，就是这个input事件
这是网站的源码
!(data/attachment/forum/202202/12/174225uzpn3pofiombokvu.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/300 "image.png")
```javascript
//我在浏览器里执行了这些代码， 改了addEventListener的回调函数,想模拟一次input事件,
const oldAddEv = window.EventTarget.prototype.addEventListener;
window.EventTarget.prototype.addEventListener = function (topic, callback) {
const callbackOld = arguments;
arguments = function (e) {
console.log("callback execute")
return callbackOld.apply(this, e)
}
return oldAddEv.apply(this, arguments);
};
```
```javascript
let ipt = document.querySelector("#wordsInput")
let input = new Event("input")
ipt.dispatchEvent(input)
```
!(data/attachment/forum/202202/12/173738ifyxyge95wk6fwvk.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/300 "image.png")
发现并没有打印“callback execute"
本人JS小白，菜的一批，希望大佬们帮我看看怎么回事

function final(count){
count = (1 / (count / 60.0)) * 1000
console.log(count)
i = 0
setInterval(function(){
f(arr)
if(i > 1){
words = document.querySelectorAll(".word")
let lastword = words
let letters = lastword.querySelectorAll("letter")
getNextWord(letters)
}
}, count)
}
//一分钟打多少个字
