需要实现的功能：点击部门展开或者折叠，点击箭头选择人员，如图：

![人员查询][SouthEast]

    </ons-page>

其中nodeType表示类型，等于1代表部门，等于3代表人员。  
childDeptAndPerson 表示当前对象包含的子元素集合,  
nodeCode表示当前节点的code,nodeName表示名称。  
fanodeCode 表示当前节点的父节点的code.  
当前页面只能展示三级关系，未能实现下拉级别不受限制。

showX 用来标志当前节点是否展开，  
xdeptCodeT用来保存上次点击的节点code,  
contentX表示当前点击的节点code
