Vue3+ElementPlus+Koa2 全栈开发后台系统=>部门管理,创建-编辑-删除功能实现⑩_第1张图片

1.创建路由

 {
                name: 'dept',
                path: '/system/dept',
                meta: {
                    title: '部门管理'
                },
                component: () => import('./../views/Dept.vue')
            },

2.构建页面

3.对接api

	getDeptList(){
        return request({
            url:'/dept/list',
            method:'get',
            data:{},
            mock:true
        })
    },
    getUserAllList(params) {
        return request({
            url: '/users/all/list',
            method: 'get',
            data: params,
            mock:true
        })
    },

4.处理业务逻辑

<script>
import { toRaw } from "vue";
import utils from "../utils/utils";
export default {
  name: "Dept",
  data() {
    return {
      queryForm: {
        deptName: "",

      deptForm: {
        parentId: [null],
        deptName: "",
        userId: "",
        userName: "",
        userEmail: "",
      },
      deptRules: {
        parentId: [
          { required: true, message: "请选择上级部门", trigger: "blur" },
        ],
        deptName: [
          { required: true, message: "请输入部门名称", trigger: "blur" },
        ],
        userName: [
          { required: true, message: "请选择负责人", trigger: "blur" },
        ],
      },
      showModel: false,
      action: "",
      allUserList: [],
      checkUserList: [],
      loading: false,
      columns: [
        {
          label: "部门名称",
          prop: "deptName",
        },

          formatter(row, column, value) {
            //规范化时间格式
            // return utils.formateDate(value);
          },
        },
        {
          label: "更新时间",
          prop: "updateTime",
          formatter(row, column, value) {
            //规范化时间格式
            // return utils.formateDate(value);
          },
        },
      ],
    };

5.Vuex存储数据

/**
 * Vuex状态管理
 */
import { createStore } from 'vuex'
import mutations from './mutations'
import storage from '../utils/storage'

const state = {
    userInfo : "" || storage.getItem("userInfo"), // 获取用户信息
    deptList: "" || storage.getItem("deptList"),
}
export default createStore({
    state,
    mutations
})
/**
 * Mutations业务层数据提交
 */
import storage from "../utils/storage";

export default {
    saveUserInfo(state,userInfo) {
        state.userInfo = userInfo;
        storage.setItem('userInfo',userInfo)
    },
    changeDeptList(state, deptList) {
        //列表部门
        state.deptList = deptList;
        storage.setItem("deptList", deptList);
      },
}
