ztree插件的使用

 在bootstrap中使用ztree插件做树形架构，由于觉得原始的树形不够美观，所以改了其中的css插件

    demo演示,以及各种属性的用法网站：  http://www.treejs.cn/v3/demo.php#_107                 

    修改页面风格网站：  http://www.lai18.com/content/2450914.html?from=cancel

     增删改查以及拖拽功能网站：   http://www.cnblogs.com/lori/archive/2013/07/04/3171655.html

参考以上网站，可根据的自己的需要进行修改

下面贴出我在做项目时的代码（前端用的是bootstrap框架，对默认的css进行了修改）

   1）先引入文件（一个css，一个js文件）

<link rel="stylesheet" href="${contextPath}/static/assets/css/zTreeStyle/metro.css"/>

"${contextPath}/static/assets/js/ztree-3.5/jquery.ztree.all-3.5.js"
2）页面

   //注意这个地方的引入，否则页面不会显示任何东西

<div id="organizationTree" class="ztree" style="width:560px; overflow:auto;"></div>  
3) js代码

    var zTree;
    var setting = {
        check: {
            enable: true
        },
        async: {
            enable: true,  //开启异步加载处理
            contentType: "application/json;charset=utf-8",
            // dataFilter: filter,//用于对 Ajax 返回数据进行预处理的函数
            dataType: "json",
            url: "${contextPath}/organization/getOrganizations/list",    //加载后台数据
            //autoParam: ["id", "name"],
            type: "post",
            //autoParam:[]
            otherParam: []
            // dataFilter: filter     //用于对 Ajax 返回数据进行预处理的函数
        },
        view: {
            expandSpeed: "",//zTree 节点展开、折叠时的动画速度，设置方法同 JQuery 动画效果中 speed 参数。

            addHoverDom: addHoverDom,  //用于当鼠标移动到节点上时，显示用户自定义控件，显示隐藏状态同 zTree 内部的编辑、删除按钮

            removeHoverDom: removeHoverDom,   //设置鼠标移到节点上，在后面显示一个按钮

        },
        edit: {
            enable: true,   //设置 zTree 进入编辑状态
            editNameSelectAll: true,
            removeTitle: '删除',
            renameTitle: '编辑',
            showRemoveBtn: true,

            }
        },
        callback: {
