Hello.vue
<template>
<div class="hello">
<h1>Now count is {{counterValue}}</h1>
<br>
</div>
</template>
<script>
import { getCount } from '../vuex/getters'
export default {
vuex: {
getters: {
counterValue: getCount
}
},
data () {
return {
}
}
}
</script>
<style scoped>
h1 {
color: #42b983;
}
</style>
Increate.vue
<template>
<div>
<button @click='increment' class="btn btn-success">click me + 3</button>
<button @click='reduce' class="btn btn-warning">click me - 1</button>
</div>
</template>
<script>
import { incrementCounter, reduceCounter } from '../vuex/action'
export default {
vuex: {
actions: {
increment: incrementCounter,
reduce: reduceCounter
}
},
data: function () {
return {
}
},
computed: {},
ready: function () {},
attached: function () {},
methods: {},
components: {}
}
</script>
<style lang="css">

src/vuex
store.js
import Vue from 'vue'
import Vuex from 'Vuex'
Vue.use(Vuex)
const state = {
count: 0
}
const mutations = {
INCREMENT (state, n) {
state.count = state.count + n
},
REDUCE (state) {
state.count--
}
}
export default new Vuex.Store({
state,
mutations
})
action.js
export const incrementCounter = ({dispatch}) => dispatch('INCREMENT', 3)
export const reduceCounter = ({dispatch}) => dispatch('REDUCE')
getters.js
export function getCount (state) {
return state.count
}
src/App.vue
<template> <div id="app"> <img class="logo" src="/UploadFiles/2021-04-02/logo.png">src/main.js
// 入口文件 import Vue from 'vue' import App from './App' import VueRouter from 'vue-router' import VueResource from 'vue-resource' /* eslint-disable import VueRouter from 'vue-router'no-new */ new Vue({ el: 'body', components: { App } }) Vue.use(VueRouter) Vue.use(VueResource) var router = new VueRouter({ hashbang: false, // 设置为true时，所有的路径都会被格式化为#！开头 history: true // 默认false,利用history.pushState(), history.replaceState()来管理浏览历史记录 }) // require('./routers')(router) router.start(App, '#app')效果图：
