关于jquery tree 树形菜单动态添加子节点的问题

<script type="text/javascript">

function getChildren(){

var node = $('#tt1').tree('getSelected') //tt1是你的树的id

if (node){

alert(“有子节点")

} else {

alert("无子节点")

}

}

</script>

<ul id="tt1" class="easyui-tree" animate="true" dnd="false">

<li>

<span>Folder</span>

<ul>

<li state="closed">

<span>Sub Folder 1</span>

<ul>

<li>

<span><a href="">File 11</a></span>

</li>

<li>

<span>File 12</span>

</li>

<li>

<span>File 13</span>

</li>

</ul>

</li>

<li>

<span>File 2</span>

</li>

<li>

<span>File 3</span>

</li>

<li>File 4</li>

<li>File 5</li>

</ul>

</li>

<li>

<span>File21</span>

</li>

</ul>

<a href="#" onclick="getChildren1()">getChildren1</a>

页面既然得到从服务器传过来的json数据之后，还要转换为Object

比如，服务器组装好的json数据：

{

id:'001',

nodeMsg:'节点1'

}

这个是ajax成功之后的回调

function(xhr){

var o = eval('(' + xhr.responseText + ')')

alert(o.id + ':' + o.nodeMsg)

}
