#引入vuex状态机 在根目录创建store目录

#在main.js引入store、注册store、挂载store在程序上 import Vue from 'vue'; import App from './App'; #import store from './store' #Vue.prototype.$store = store

const app = new Vue({

store,

...App

}) app.$mount()

#在页面内使用store的属性 <view @tap="add"> import { mapState,mapGetters,mapMutations } from 'vuex'//引入mapState export default { data() { return {} }, #单纯访问属性值 computed:{ tokenEv() { return this.$store.state.token; } }, computed:mapState({ // 从state中拿到数据 箭头函数可使代码更简练 token: state => state.token, }), computed:mapState(['token']), computed: { ...mapState({ token: function (state) { return '追加的' + state.token }, userInfo: state => state.userInfo, }) }, computed:{ ...mapState([ 'token', 'userInfo', 'count', 'obj' ]) }, computed: { ...mapState({ token: state => state.moduleA.token, count: state => state.moduleB.count }), }, #单纯访问方法 computed: { todos() { return this.$store.getters.doneTodos } }, computed: { doneTodosCount() { return this.$store.getters.doneTodosCount } }, computed: { getTodoById() { return this.$store.getters.getTodoById(1) } }, computed: { // 使用对象展开运算符将 getter 混入 computed 对象中 ...mapGetters([ 'doneTodos', 'doneTodosCount', 'getTodoById' // ... ]) }, onLoad(options) { #改变状态机里面的值 this.$store.commit('setToken', 'token已改变'); this.$store.commit('updateUserInfo',{userInfo:'用户信息'}) this.$store.commit({ type: 'updateUserInfo', userInfo: '新方式更新用户信息' }) this.$store.commit('newProp',{c:'吃火锅'}) console.log(this.token); this.add(); this.$store.dispatch('addCountAction') this.$store.dispatch('addCountAction2',{amount:10}) this.$store.dispatch('addCountAction3',{amount:30}) setTimeout(()=>{ console.log(this.count,388); },3000) }, methods: { ...mapMutations(['add']),//对象展开运算符直接拿到add } }
