easyUI 之动态填充树状列表【easyui-tree】

通过服务器API请求数据，使用【easyui-tree】实现动态填充单位列表的展示 

 <!--右侧单位列表开始-->
        <div id="unit-list" class="easyui-panel">
            <div id="unit-list_title">
                单位列表
                <a id="unit-list-close-btn" class="fa fa-times" style="float: right" href="javascript:;"></a>
            </div>
            <ul id="tt" class="easyui-tree" data-options="url:'',method:'get',animate:true"></ul>
        </div>
        <!--右侧单位列表结束-->

var EnterPriseAllList_tree = format_tree_data(EnterPriseAllList);//格式化单位列表
$("#tt").tree({//Easy ui tree 加载列表 
     data: EnterPriseAllList_tree
});
