這個(gè)哪里有問(wèn)題，求教，感謝

錯(cuò)誤1：數(shù)組中的項(xiàng)都是location對(duì)象的屬性，形式上應(yīng)寫為：location.protocol等等；
錯(cuò)誤2：for循環(huán)本身寫得有問(wèn)題；如果你想這么寫，那么上面的數(shù)組中應(yīng)該全是字符串屬性，那樣的話應(yīng)寫為：["protocol","host"]等等。
以上

其實(shí)也可以寫成這樣：
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>location</title>
</head>
?<script type="text/javascript">
?var kl=[location.protocol,location.host,location.pathname,location.search,location.hash];
? for(var num=0;num<=4;num++)
? {
????? document.write(kl[num]+"<br>");
? }
?</script>
<body>
</body>
</html>
