js实现打字小游戏
今日闲来无事，想试一试模拟打字游戏，下面是效果图，会记录判断打字，如果在外围添加setInterval函数，可以实现测试打字速度的功能。
html
<div class="wrapper">
<div id="text">A</div>
<input type="text" id="ipt">
</div>
css
body,
html {
width: 100%;
height: 100%;
}
.wrapper {
width: 400px;
margin: 20px auto;
}
div {
font-size: 100px;
font-weight: 900;
text-align: center;
}
input{
width: 400px;
margin: 20px auto;
}
js
var str = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
var text = document.getElementById('text')
var ipt = document.getElementById('ipt')
var res;
var newRes;
var random = Math.round(Math.random() * 25);
var count = 0
window.onkeyup = function (e) {
var random = Math.round(Math.random() * 25);
newRes = str[random]
res = text.innerHTML
text.innerHTML = newRes
if(e.keyCode == res.charCodeAt(0)){
count++;
ipt.value = '';
}else{
alert('game over' + ' ' +'您的得分是'+ ':' + count)
count = 0;
ipt.value = '';
}
}
