vue项目中的js文件使用vuex

使用场景：假设有一个接口，需要在很多页面获取一遍并且将接口的返回值保存起来，这样就能使用vuex，将值保存在vuex中
实现：vuex中新建firmModule.js文件，编写存储值的代码，utils/getFirmData.js用来调接口获取值并将值存储在vuex中，xxx.vue中调取getFirmData.js中的方法，并且在watch中监听vuex的值实现给xxx.vue的form赋值

store/modules/firmModule.js

const state = {firmData: {firmId: undefined,firmName: undefined,},
};const mutations = {SET_FIRM_DATA(state, firmData) {state.firmData = firmData;},
};const actions = {setFirmData({ commit }, firmData) {commit("SET_FIRM_DATA", firmData);},
};export default {namespace: true,state,mutations,actions,
};

store/index.js

import Vue from "vue";
import Vuex from "vuex";
import firmModule from "@/store/modules/firmModule";
Vue.use(Vuex);const store = new Vuex.Store({modules: {firmModule,},
});export default store;

utils/getFirmData.js

/*** @Event 获取企业信息* @description: 最终数据存储到vuex中 store.state.firmModule.firmData* @author: mhf* @time: 2023-11-16 21:41:05**/
import { queryUserId } from "@/api/enterpriseManage/riskControl.js"; // 接口
import { isEmptyArray } from "@/utils/publicFun"; // 判断是否是空数组
import store from "@/store";export async function getFirmData() {try {const user = localStorage.getItem('user');if (!user) {throw new Error('无法获取用户信息');}const userId = JSON.parse(user).user.userId;const res = await queryUserId({ userId })if (isEmptyArray(res.data)) {throw new Error('查询结果为空')}await store.dispatch('setFirmData', res.data[0])} catch (error) {throw new Error('失败:' + error)}
}// isEmptyArray方法如下：/*** @Event 判断是否是空数组* @description:* @author: mhf* @time: 2023-11-16 17:26:31**/
export function isEmptyArray(arr) {if (Object.prototype.toString.call(arr) !== "[object Array]") return;return arr.length === 0;
}

xxx.vue

import { getFirmData } from "@/utils/getFirmData";// 监听vuex中的数据给formData赋值watch: {"$store.state.firmModule.firmData"(obj) {this.$set(this.formData, "firmName", obj.firmName);this.$set(this.formData, "firmId", obj.id);}},created() {getFirmData();},

注意 eslint检测async await配置如下

.eslintrc.js

// ESlint 检查配置
module.exports = {root: true,parserOptions: {parser: 'babel-eslint',sourceType: 'module',"ecmaVersion": 2020, // 需要此项},env: {browser: true,node: true,es6: true},extends: [],// add your custom rules here// it is base on https://github.com/vuejs/eslint-config-vuerules: {}
}
