标题: js获取属性节点的问题
function divAttributes(){//获取属性节点
  var str = "";
  var obj = document.getElementById("divid");
  var att = obj.attributes;
  
  for(var i=0; i<att.length; i++){
   str += "name:"+att[i].nodeName+"  --type:"+att[i].nodeType+"  --value:"+att[i].nodeValue+"<br/>";
  }
  document.write(str);
}

<input type="button" value="小按钮" />
<div id="divid">
nihao
</div>

为什么这个例子的div只有一个属性节点呢？？
