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

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>

<meta http-equiv="content-type" content="text/html; charset=UTF-8">

<link rel="stylesheet" type="text/css" href="zTree_v3/css/demo.css" rel="external nofollow" >

<link rel="stylesheet" type="text/css" href="zTree_v3/css/zTreeStyle/zTreeStyle.css" rel="external nofollow" >

<script type="text/javascript" src="zTree_v3/js/jquery-1.4.4.min.js"></script>

<script type="text/javascript" src="zTree_v3/js/jquery.ztree.core.min.js"></script>

<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:121, pId:12, name:"黄石港区"},

{ id:122, pId:12, name:"西塞山区"},

{ id:123, pId:12, name:"下陆区"},

{ id:124, pId:12, name:"铁山区"},

{ 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);
