硅谷(12)菜单管理

菜单管理模块

11.1 模块初始界面

11.1.1 API&&type

API:

import request from '@/utils/request'
import type { PermisstionResponseData, MenuParams } from './type'
//枚举地址
enum API {//获取全部菜单与按钮的标识数据ALLPERMISSTION_URL = '/admin/acl/permission',
}
//获取菜单数据
export const reqAllPermisstion = () => {return request.get<any, PermisstionResponseData>(API.ALLPERMISSTION_URL)
}

TYPE:

注意：type这里使用了嵌套

//数据类型定义
export interface ResponseData {code: numbermessage: stringok: boolean
}
//菜单数据与按钮数据的ts类型
export interface Permisstion {id?: numbercreateTime: stringupdateTime: stringpid: numbername: stringcode: nulltoCode: nulltype: numberstatus: nulllevel: numberchildren?: PermisstionListselect: boolean
}
export type PermisstionList = Permisstion[]
//菜单接口返回的数据类型
export interface PermisstionResponseData extends ResponseData {data: PermisstionList
}

11.1.2 组件获取初始数据

//存储菜单的数据
let PermisstionArr = ref<PermisstionList>([])
//组件挂载完毕
onMounted(() => {getHasPermisstion()
})
//获取菜单数据的方法
const getHasPermisstion = async () => {let result: PermisstionResponseData = await reqAllPermisstion()if (result.code == 200) {PermisstionArr.value = result.data}
}

11.1.3 模板展示数据

<div><el-table:data="PermisstionArr"style="width: 100%; margin-bottom: 20px"row-key="id"border><el-table-column label="名称" prop="name"></el-table-column><el-table-column label="权限值" prop="code"></el-table-column><el-table-column label="修改时间" prop="updateTime"></el-table-column><el-table-column label="操作"><!-- row:即为已有的菜单对象|按钮的对象的数据 --><template #="{ row, $index }"><el-buttontype="primary"size="small":disabled="row.level == 4 ? true : false">{{ row.level == 3 ? '添加功能' : '添加菜单' }}</el-button><el-buttontype="primary"size="small":disabled="row.level == 1 ? true : false">编辑</el-button><el-buttontype="primary"size="small":disabled="row.level == 1 ? true : false">删除</el-button></template></el-table-column></el-table></div>

11.2 更新与添加菜单功能

11.2.1 API&&TYPE

API：

//给某一级菜单新增一个子菜单ADDMENU_URL = '/admin/acl/permission/save',//更新某一个已有的菜单UPDATE_URL = '/admin/acl/permission/update',//添加与更新菜单的方法
export const reqAddOrUpdateMenu = (data: MenuParams) => {if (data.id) {return request.put<any, any>(API.UPDATE_URL, data)} else {return request.post<any, any>(API.ADDMENU_URL, data)}
}

11.2.2 对话框静态

<!-- 对话框组件:添加或者更新已有的菜单的数据结构 --><el-dialogv-model="dialogVisible"><!-- 表单组件:收集新增与已有的菜单的数据 --><el-form><el-form-item label="名称"><el-inputplaceholder="请你输入菜单名称"></el-input></el-form-item><el-form-item label="权限"><el-inputplaceholder="请你输入权限数值"></el-input></el-form-item></el-form><template #footer><span class="dialog-footer"><el-button @click="dialogVisible = false">取消</el-button><el-button type="primary" @click="save">确定</el-button></span></template></el-dialog>

11.2.3 收集数据

需要的参数一共是4个，其中code、name由v-model绑定的对话框收集。其余俩个通过点击按钮传递的参数收集。

//携带的参数
let menuData = reactive<MenuParams>({code: '',level: 0,name: '',pid: 0,
})

//添加菜单按钮的回调
const addPermisstion = (row: Permisstion) => {//清空数据Object.assign(menuData, {id: 0,code: '',level: 0,name: '',pid: 0,})//对话框显示出来dialogVisible.value = true//收集新增的菜单的level数值menuData.level = row.level + 1//给谁新增子菜单menuData.pid = row.id as number
}
//编辑已有的菜单
const updatePermisstion = (row: Permisstion) => {dialogVisible.value = true//点击修改按钮:收集已有的菜单的数据进行更新Object.assign(menuData, row)
}

11.2.4 发送请求

//确定按钮的回调
const save = async () => {//发请求:新增子菜单|更新某一个已有的菜单的数据let result: any = await reqAddOrUpdateMenu(menuData)if (result.code == 200) {//对话框隐藏dialogVisible.value = false//提示信息ElMessage({type: 'success',message: menuData.id ? '更新成功' : '添加成功',})//再次获取全部最新的菜单的数据getHasPermisstion()}
}

11.3 删除模块

11.3.1 API

//删除已有的菜单DELETEMENU_URL = '/admin/acl/permission/remove/',
//删除某一个已有的菜单
export const reqRemoveMenu = (id: number) => {return request.delete<any, any>(API.DELETEMENU_URL + id)
}

11.3.2 删除点击函数

<el-popconfirm:title="`你确定要删除${row.name}?`"width="260px"@confirm="removeMenu(row.id)"><template #reference><el-buttontype="primary"size="small":disabled="row.level == 1 ? true : false">删除</el-button></template></el-popconfirm>

11.3.3 删除的回调

//删除按钮回调
const removeMenu = async (id: number) => {let result = await reqRemoveMenu(id)if (result.code == 200) {ElMessage({ type: 'success', message: '删除成功' })getHasPermisstion()}
}
