这篇文章将为大家详细讲解有关基于zTree中Jsp通用动态级联树结构是怎么样的，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
1、categoryTree.html 通用页面
<link rel="stylesheet" href="/static/plugins/zTree_v3/css/zTreeStyle.css" type="text/css">
<style>
/*展示树状结构的样式*/
ul.ztree {position:relative;top: 32px;left:0px;z-index:999;border: 1px solid #617775;background: #f0f7fb;width:220px;height:360px;overflow-y:scroll;overflow-x:auto;display: none}
</style>
<script type="text/javascript" src="/static/plugins/zTree_v3/js/jquery-1.4.4.min.js"></script>
<script type="text/javascript" src="/static/plugins/zTree_v3/js/jquery.ztree.core.js"></script>
<SCRIPT type="text/javascript" >
var node_id ,node_name;
var zTreeObj,
setting = {
view: {
selectedMulti: false //多选选项
},
data:{//定义数据规范
simpleData:{
enable:false,//是否使用简单的数据结构，本例使用标准json树状结构
idKey:'cat_id',//nodeId字段名称
pIdKey:'parent_id',//parentId字段名称
rootPId:0 //跟nodeId的值
},
key:{ //字段名称定义
name:"cat_name",//展示名称
children:"nodes"//子节点对象
}
}
},
zTreeNodes = [];
//加载动态数据
function loadTree(data){
if(data && data.length>0){
zTreeNodes = data;
zTreeObj = $.fn.zTree.init($("#tree"), setting, zTreeNodes);
}
}
$(document).ready(function(){
$.post("/category/getCategoryTree",null,loadTree);
});
</SCRIPT>
<ul id="tree" class="ztree"></ul>2、调用方法
<div class="t_text ml10" id="category">
<c:import url="../common/categoryTree.jsp"/> <!--如果是静态页面可以使用jquery.load() 方法 -->
<input type="hidden" name="cat_id" id="cat_id" value="${pageParam.cat_id }" />
<input placeholder="类别" type="text" name="cat_name" id="cat_name" />
</div>3.controller
