1.首先目录结构大致如下：

vuex使用备忘_搜索栏

2.mutation-type.js

vuex使用备忘_搜索栏_02

3.index.js

import Vue from 'vue';
import Vuex from 'vuex';
import user from './modules/user';
import asideMenu from './modules/asideMenu';
import tableDetail from './modules/tableDetail';
import search from './modules/search';
import apiData from './modules/apiData';
import scrollTop from './modules/scrollTop';
import formDialog from './modules/formDialog';
import userManage from './modules/authManageStore/userManage';
import roleManage from './modules/authManageStore/roleManage';
import authManage from './modules/authManageStore/authManage';

Vue.use(Vuex);

export default new Vuex.Store({
  state: {},
  getters: {},
  actions: {},
  mutations: {},
  modules: {
    user,
    asideMenu,
    tableDetail,
    search,
    apiData,
    scrollTop,
    userManage,
    roleManage,
    authManage,
    formDialog
  }
});


4.modules下的js文件

import * as Api from '../../data';
import * as types from '../mutation-type';

const state = {
  searchInfo: []
};

const mutations = {
  [types.SETSEARCHBYCONDITION] (state, payload) {
    const { datas } = payload;
    state.searchInfo = Object.assign({}, datas);
  }
};

const actions = {
  // 搜索栏信息
  async getSearchByCondition ({ commit }, payload) {
    const { layerId, colName, tabName } = payload;
    await Api.getSearchByCondition(layerId, colName, tabName).then(res => {
      if (res.errorCode === 'SUCCESS') {
        commit(types.SETSEARCHBYCONDITION, {
          datas: res
        });
      }
    });
  }
};

export default {
  namespaced: true,
  state,
  mutations,
  actions
};
import * as Api from '../../data';
import * as types from '../mutation-type';
const state = {
  layerMenus: [],
  classifyMenus: [],
  groups: {},
  tabs: {},
  description: '',
  defaultMenus: {},
  authFlag: false,
  // type 1 刷新正常树 2 刷新收藏树
  isRefreshObj: {isRefresh: false, type: 1}
};

const mutations = {
  [types.setRefreshMenu] (state, payload) {
    state.isRefreshObj.isRefresh = !state.isRefreshObj.isRefresh;
    state.isRefreshObj.type = payload.type;
  },
  [types.SETDEFAULTMENUS] (state, payload) {
    const { datas } = payload;
    state.defaultMenus = Object.assign({}, datas);
  },


5.组件中使用 用于兄弟组件事件通信和传参(载荷)

vuex使用备忘_vuex_03

vuex使用备忘_搜索栏_04

vuex使用备忘_vuex_05

此处对象监听用deep: true

vuex使用备忘_vuex_06
