<div id="box">

<span>22</span>
</div>
<script type="text/javascript">
var box = document.getElementById("box");
fn(box.nextSibling.nodeName);//nextSibling返回此对象往后的紧跟节点,以对象方式返回;nodeName返回节点名称
var copy=document.getElementById("box").lastChild.cloneNode("aaa");
document.getElementsByTagName("span").appendChild(copy);
function fn(value){
return document.write(value+'\n');
}
</script>
</body>
</html>
实在找不到这26行哪里错了
