document.write("li["+(i+1)+"]:"+"<br/>"+"节点名:"+node[i].nodeName+"<br/>"); 为什么节点名的序号加打引号和加号
<!DOCTYPE HTML>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<script type="text/javascript">
var node=document.getElementsByTagName("li");
for(var i=0;i<node.length;i++){
document.write("li["+(i+1)+"]:"+"<br/>"+"节点名:"+node[i].nodeName+"<br/>");
document.write("节点值:"+node[i].nodeValue+"<br/>");
document.write("节点类型:"+node[i].nodeType+"<br/><br/>");
