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: number
  message: string
  ok: boolean
}
//菜单数据与按钮数据的ts类型
export interface Permisstion {
  id?: number
  createTime: string
  updateTime: string
  pid: number
  name: string
  code: null
  toCode: null
  type: number
  status: null
  level: number
  children?: PermisstionList
  select: 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-button
            type="primary"
            size="small"
            :disabled="row.level == 4 ? true : false"
          >
            {{ row.level == 3 ? '添加功能' : '添加菜单' }}
          </el-button>
          <el-button
            type="primary"
            size="small"
            :disabled="row.level == 1 ? true : false"
          >
            编辑
          </el-button>
          <el-button
            type="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-dialog
      v-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-input
            placeholder="请你输入菜单名称"
          ></el-input>
        </el-form-item>
        <el-form-item label="权限">
          <el-input
            placeholder="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-button
                type="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()
  }
}
