这个编译器的问题，VS code 实测并不会出问题 代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta http-equiv="X-UA-Compatible" content="ie=edge" />
<title>Document</title>
<script>
var num = 0;
function startCount() {
document.getElementById("count").value = num;
num = num + 1;
setTimeout(startCount,1000)
}
</script>
</head>
<body>
<input type="text" id="count" />
<input type="button" value="开始计数" onclick="startCount()" />
</body>
</html>
