FF不支持javascript的for in语句吗？
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN " "http://www.w3.org/TR/html4/loose.dtd ">
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=GB18030 ">
<title> Insert title here </title>
</head>
<body>
<p id= "test "> </p>
<script type= "text/javascript ">
for (i in window){
test.innerHTML = test.innerHTML+i+ " <br> ";
}
</script>
</body>
</html>
上面在代码什么在P标签在FF中没有任何输出，而在IE和OPERA则有输出？
[解决办法]
那是因为在FF下不能直接用ID来引用元素
用document.getElementById( "test ").innerHTML=
