正在回答
应该先输入再判断大小
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

</head>
<body>
<script>
//补充代码
var random = Math.floor(Math.random()*10+1);
var input;
while (input != random) {
input = Number(prompt("请输入你猜的数字"));
if (input < random) {
alert("输入的数字小了");
} else if (input > random) {
alert("输入的数字大了");
} else {
alert("恭喜你猜对了");
}
}
</script>
