【原创】MVC+ZTree实现权限树的功能

2、html代码

权限树：

3、JS代码

var setting = {

async: {

enable: true,

url: '/RoleToPerssion/GetPerssionTree',//异步加载时的请求地址

autoParam: ["roleid"],//提交参数

type: 'get',

dataType: 'json'

},

check: {

enable: true,   //true / false 分别表示 显示 / 不显示 复选框或单选框

autoCheckTrigger: true,   //true / false 分别表示 触发 / 不触发 事件回调函数

chkStyle: "checkbox",   //勾选框类型(checkbox 或 radio）

//chkboxType: { "Y": "p", "N": "s" }   //勾选 checkbox 对于父子节点的关联关系

},

checkable: true,

showIcon: true,

showLine: true,

data: {

simpleData: {

enable: true

}

},

expandSpeed: "",

callback: {

onClick: zTreeOnClick

}

};

$(document).ready(function () {

$.ajax({

url: '/RoleToPerssion/GetPerssionTree?roleid=""',//异步加载时的请求地址

type: 'get',

dataType: 'json',

success: function (data) {

$.fn.zTree.init($("#treeDemo"), setting, data);

}

});

});

//单击时获取zTree节点的Id,和value的值

function zTreeOnClick(event, treeId, treeNode, clickFlag) {

// var treeValue = treeNode.Id + "," + treeNode.name;

//alert(treeNode.Id + "," + treeNode.name);

};

//获取选中value值

function GetIDs() {

var treeObj = $.fn.zTree.getZTreeObj("treeDemo"),

nodes = treeObj.getCheckedNodes(true),

v = "";

var ids = "";

for (var i = 0; i < nodes.length; i++) {

v += nodes[i].name + ",";

if (nodes[i].PId != "0") {

ids += nodes[i].Id + ",";

}

}

}

4、Mvc后台主要代码

public class PerssonTreeModel

{

public string Id { get; set; }

///

/// 权限名称

///

public string name { get; set; }

public string PId { get; set; }

///

/// 子节点

///

public List children { get; set; }

///

/// 是否有复选框

///

public bool nocheck { get; set; }

///

/// 是否展开节点

///

public bool open { get; set; }

}

///

/// 获取目录树的json

///

///

///

public JsonResult GetPerssionTree(string roleid)

{

var parentlist = perssionbll.GetAllList().Where(m=>m.ParentId=="0").ToList();

var childrenlist = perssionbll.GetAllList().Where(m => m.ParentId != "0").ToList();

var result = new List();

if (parentlist!=null && parentlist.Count>0)

{

foreach(var item in parentlist)

{

result.Add(new PerssonTreeModel {

Id = item.id,

name = item.Title,

PId = item.ParentId,

nocheck = true,

open = true,

children = GetChildrenList(item.id,childrenlist)

});

}

}

return Json(result,JsonRequestBehavior.AllowGet);

}

///

/// 获取一级权限下面的子节点

///

///

///

///

public List GetChildrenList(string id, List list)

{

var result = new List();

list = list.Where(m => m.ParentId == id).ToList();

if (list != null && list.Count > 0)

{

foreach (var item in list)

{

result.Add(new PerssonTreeModel

{

Id = item.id,

name = item.Title,

PId = id,

open = false,

nocheck = false,

children = null

});

}

}

return result;

}
