vuex主要包含以下五个部分:
State // 存储变量、数据Getter // 类似计算属性Mutation // 唯一修改state的方法Action // 异步调用MutationModule // 将store模块化vuex的modules使用创建目录在此示例中，我创建了两个store文件，分别是 profile.js和custom.js，一个根文件index.js
custom.js
const customs = { namespaced: true, // 创建命名空间 state: { // 存储变量 showAlert: false }, mutations: { // 定义修改state方法 CHANGESHOW: (state, params) => { state.showAlert = !state.showAlert } }, actions: { // 异步调用mutations setShow: ({ commit }) => { commit('CHANGESHOW') } }, getters: { // 将数据过滤输出 bodyShow: state => state.showAlert }}export default customs登录后复制profile.js
const profile = { namespaced: true, state: { name: 'common name', age: 18, bool: false }, mutations: { CHANGEMSG: (state, params) => { state.name = params }, CHANGEAGE: (state, params) => { state.name = params }, CHANGEBOOL: (state) => { state.bool = !state.bool } }, actions: { setName: ({ commit }) => { commit('CHANGEMSG', 'Vuex common name') }, setAge: ({ commit }) => { commit('CHANGEAGE', 81) }, setBool: ({ commit }) => { commit('CHANGEBOOL') } }, getters: { vuexName: state => state.name, vuexAge: state => state.age, vuexBool: state => state.bool }}export default common登录后复制index.js
import Vue from 'vue'import Vuex from 'vuex'// 引入子storeimport profile from './modules/profile'import customs from './modules/customs'// Vue.use(Vuex)const store = new Vuex.Store({ modules: { profile, customs }})export default store // 导出store，以便于后续使用登录后复制在需要使用的.vue文件里进行使用。方法如下
index.vue
<template><div> name: <h5>{{vuexName}}</h5> <button @click='setName'>chenge name</button> age: <h5>{{vuexAge}}</h5> <button @click='setAge'>chenge age</button> bool: <h5>{{vuexBool}}</h5> <button @click='setBool'>chenge bool</button> <br/> <span @click='setShow' style='display:inline-block;width:200px;height:30px;border:1px solid #999;border-radius:5px;text-align:center;line-height:30px;cursor: pointer;'>click me ,change showAlert</span> <em>{{bodyShow}}</em></div></template><script>import { mapActions, mapGetters } from 'vuex'export default {computed: { ...mapGetters('profile', ['vuexName', 'vuexAge', 'vuexBool']), ...mapGetters('customs', ['bodyShow']) },methods: { ...mapActions('customs', ['setShow']), ...mapActions('profile', ['setName', 'setAge', 'setBool']),}</script><style></style>登录后复制app.js
import Vue from 'vue';import VueRouter from 'vue-router';// styleimport './../../sass/app.scss';// Componentsimport Main from './Main.vue';import routes from './routes';// storeimport store from './store'; // 将store挂载到VueVue.use(VueRouter);const router = new VueRouter({ routes, saveScrollPosition: true,});new Vue({ router, store, ...Main }).$mount('#app');登录后复制初始效果图 ⬇️ 点击按钮之后效果图 ⬇️ 至此，modules使用流程演示完毕！【相关推荐：vue.js视频教程】
