var a=document.getElementsByTagName("li");
for(i=0;i<a.length;i++){
b=a[i].getAttribute("Name");
c=a[i].getAttribute("Value");
d=a[i].getAttribute("Type");
document.write("li标签的名称是："+b+"<br/>");
document.write("li标签的值是："+c+"<br/>");
document.write("li标签的类型是："+d+"<br/>");
}
getAttribute为什么出来的结果都是null啊

看我的代码：
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>节点属性</title>
</head>
<body>
<ul>
<li>javascript</li>
<li>HTML/CSS</li>
<li>jQuery</li>
</ul>
<script type="text/javascript">
function getNodeInfo() {
var node = document.getElementsByTagName("li");
for (var i=0;i<node.length;i++) {
var nodeOne = node[i];
document.write("nodeName:" + nodeOne.nodeName + " nodeValue:" + nodeOne.nodeValue + " nodeType:" + nodeOne.nodeType + "<br>");
}
}
getNodeInfo();
</script>
</body>
</html>
