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)
