如果讓他每個(gè)結(jié)果都輸出一次，要怎么寫這個(gè)代碼？有趣
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Math </title>
<script type="text/javascript">
x=3.3
x=-0.1
x=-9.9
x=8.9
document.write(Math.ceil(x)+"<br />")
</script>
</head>
<body>
</body>
</html>
誰能用之前所學(xué)的循環(huán)來做一下

<script type="text/javascript">
var x =[3.3,-0.1,-9.9,8.9];
for(var i=0;i<x.length;i++){
?document.write(Math.ceil(x[i])+"<br/>")
}
</script>

寫了一個(gè)，還有其他方法嗎 簡單便捷
