//html
<ul id="tree"></ul>

 js

 function initTree() {
        $(‘#tree‘).tree({
            url: ‘/OnlineMonitoring/ashx/departMgr.ashx?type=tree‘
                 
        });

    }

 后台

  根据父id返回当前子节点就好了。(父id为0时返回根节点)

json示例

     [
    {
        "id": "2",
        "text": "监事会",
        "state": "closed"
    },
    {
        "id": "4259045978553",
        "text": "2",
        "state": "open"
    },
    {
        "id": "4259055249969",
        "text": "a",
        "state": "open"
    }
]

id:node的id

text:节点名称

state:closed或open(closed说明有子项)

贴上一个sqlserver procedure:

  

 create procedure [dbo].[Tree]
    @pid varchar(30)
 as
 begin
    select 
     a.department_id as [id],
     a.department_name as [text],
     case
     when
     (select COUNT(department_id) from dbo.department_info as b where b.department_parent_id=a.department_id)>0
     then closed else open
     end as [state]
     from dbo.department_info as a where a.department_parent_id=@pid;
 end

根据pid返回树(pid为0时返回根节点)
