效果演示
上代码：
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Title</title><style type="text/css">span{font-size: larger;margin: 20px;}#score{background-color: red;color: white;position: absolute;left:90%;top: 90%;}</style>
</head>
<span id="score">
0
</span>
<input type="file" name="file" multiple="multiple" id="files" onchange="choosefile()" />
<body>
<script>var content = "";var score = 0;//这里可以使用固定单词var words= ["apple","horizontal","vertical","vector","ghost","evil","banana","polo","curve","deploy"];var fileWords = [];var str = '';var count = 0;//单词生成速度，可以根据当前得分来设置，得分越高速度越快，比如当得分大于200时速度设为2，大于300百是速度设为3var speed = 1;function randWords(){if(fileWords.length>0){for (var i = 0; i <words.length ; i++) {var rand = Math.floor(Math.random()*fileWords.length);words[i] = fileWords[rand];}}}setInterval(()=>{if(count%(6-speed)===0){//从文件读取到的单词，随机选取10个单词this.randWords();let divElement = document.createElement('div');for (var i = 0; i <words.length ; i++) {var rand = Math.floor(Math.random()*words.length);var span = document.createElement('span');span.innerText = words[rand];divElement.appendChild(span);document.body.appendChild(divElement);}}count++;},1000)document.addEventListener("keydown",function (event) {str+=event.key;console.log(str);var spans = document.getElementsByTagName('span');var matchCnt = 0;for (var i = 0; i <spans.length ; i++) {if(str.includes(spans[i].innerText)){spans[i].style.color = 'red'score++;matchCnt++;}}if(matchCnt>0){str = '';}document.getElementById('score').innerText = score;//清除全部打出的一行var divs = document.getElementsByTagName('div');for (var i = 0; i <divs.length ; i++) {var children = divs[i].children;var redCnt = 0;for (var j = 0; j <children.length ; j++) {if(children[j].style.color === 'red'){redCnt++;}}if(redCnt===children.length){document.body.removeChild(divs[i]);}}});function choosefile () {var fileList = document.getElementById('files').files;var nameStr = '';for (var i = 0; i < fileList.length; i++) {nameStr += `${i === 0 ?
