Ztree-

ztree笔记：

1.ztree
  官网：http://www.treejs.cn/v3/main.php#_zTreeInfo
  使用：
    1.引入ztree.js及ztree所依赖的jquery
    
    2.准备ztree展示的一个容器
      <div class="zTreeDemoBackground left">
        <ul id="treeDemo" class="ztree"></ul>
      </div>
      
    3.填充数据：
    
       var setting = {    };

        var zNodes =[
            { name:"父节点1 - 展开", open:true,
                children: [
                    { name:"父节点11 - 折叠",
                        children: [
                            { name:"叶子节点111"},
                            { name:"叶子节点112"},
                            { name:"叶子节点113"},
                            { name:"叶子节点114"}
                        ]},
                    { name:"父节点12 - 折叠",
                        children: [
                            { name:"叶子节点121"},
                            { name:"叶子节点122"},
                            { name:"叶子节点123"},
                            { name:"叶子节点124"}
                        ]},
                    { name:"父节点13 - 没有子节点", isParent:true}
                ]},
            { name:"父节点2 - 折叠",
                children: [
                    { name:"父节点21 - 展开", open:true,
                        children: [
                            { name:"叶子节点211"},
                            { name:"叶子节点212"},
                            { name:"叶子节点213"},
                            { name:"叶子节点214"}
                        ]},
                    { name:"父节点22 - 折叠",
                        children: [
                            { name:"叶子节点221"},
                            { name:"叶子节点222"},
                            { name:"叶子节点223"},
                            { name:"叶子节点224"}
                        ]},
                    { name:"父节点23 - 折叠",
                        children: [
                            { name:"叶子节点231"},
                            { name:"叶子节点232"},
                            { name:"叶子节点233"},
                            { name:"叶子节点234"}
                        ]}
                ]},
            { name:"父节点3 - 没有子节点", isParent:true}

        ];
    
        $(document).ready(function(){
            $.fn.zTree.init($("#treeDemo"), setting, zNodes);
        });
