断断续续的烟雨给江南披上了一件白色的纱衣，这件飘若浮云，清净如水的嫁纱，迷蒙了往昔，模糊了过去。我开始在其中憧憬，永远的置身于这种氛围中，让世俗的纠缠远离。
本文实例讲述了jQuery插件zTree实现获取当前选中节点在同级节点中序号的方法。分享给大家供大家参考，具体如下：
1、实现代码：
<!DOCTYPE html>
<html>
<head>
<title>zTree实现基本树</title>

<script type="text/javascript">
<!--
var setting = {
data: {
simpleData: {
enable: true
}
}
};
var zNodes =[
{ id:1, pId:0, name:"湖北省", open:true},
{ id:11, pId:1, name:"武汉市", open:true},
{ id:111, pId:11, name:"汉口"},
{ id:112, pId:11, name:"汉阳"},
{ id:113, pId:11, name:"武昌"},
{ id:12, pId:1, name:"黄石市"},

{ id:13, pId:1, name:"黄冈市"},
{ id:131, pId:13, name:"黄州区"},
{ id:132, pId:13, name:"麻城市"},
{ id:133, pId:13, name:"武穴市"},
{ id:134, pId:13, name:"团风县"},
{ id:135, pId:13, name:"浠水县"},
{ id:136, pId:13, name:"罗田县"},
{ id:137, pId:13, name:"英山县"},
{ id:2, pId:0, name:"湖南省", open:true},
{ id:21, pId:2, name:"长沙市", open:true},
{ id:211, pId:21, name:"芙蓉区"},
{ id:212, pId:21, name:"天心区"},
{ id:213, pId:21, name:"岳麓区"},
{ id:214, pId:21, name:"开福区"},
{ id:22, pId:2, name:"株洲市"},
{ id:221, pId:22, name:"天元区"},
{ id:222, pId:22, name:"荷塘区"},
{ id:223, pId:22, name:"芦淞区"},
{ id:224, pId:22, name:"石峰区"}
];
$(document).ready(function(){
$.fn.zTree.init($("#baseTree"), setting, zNodes);
});
/**
* 获取当前选中的第一个节点在同级节点中的序号
*/
function indexNodes()
{
var treeObj = $.fn.zTree.getZTreeObj("baseTree");
//获取选中的节点
var nodes = treeObj.getSelectedNodes();
if (nodes.length>0)
{
for(var i=0;i<nodes.length;i++)
{
var index = treeObj.getNodeIndex(nodes[i]);
alert("获取当前选中的第一个节点在同级节点中的序号："+index);
}
}
}
//-->
</script>
</head>
<body>
<div class="content_wrap">
<div class="zTreeDemoBackground left">
<ul id="baseTree" class="ztree" style="height: 300px; width:200px; overflow-y: auto"></ul>
<input type="button" id="btn" onclick="indexNodes()" value="获取当前选中的第一个节点在同级节点中的序号"/>
</div>
</div>
</body>
</html>
2、实现效果图：
（1）初始化
（2）选择“汉口”时
（3）选择“汉阳”时
3、源码说明：
var index = treeObj.getNodeIndex(nodes[i]);
alert("获取当前选中的第一个节点在同级节点中的序号："+index);
