vuex的模块化和namespaced

这里主要是将store里面的index.js这个文件变得更加有条理性一点，使得整个代码看起来比较清晰

主要的变动在于count.vue,person.vue,index.js

count.vue

<template>
	<div>
		<h1>当前求和为：{{sum}}</h1>
		<h3>当前求和放大10倍为:{{bigSum}}</h3>
		<h3>我在{{school}} 学习{{subject}}</h3>
		<h3 style="color:red">下方组件的总人数是：{{personList.length}}</h3>
		<select v-model.number="n">
			<option value="1">1</option>
			<option value="2">2</option>
			<option value="3">3</option>
		</select>
		<button @click="increment(n)">+</button>
		<button @click="decrement(n)">-</button>
		<button @click="incrementOdd(n)">当前求和为奇数再加</button>
		<button @click="incrementWait(n)">等一等再加</button>
	</div>
</template>
 
<script>
    import {mapActions, mapGetters, mapMutations, mapState} from 'vuex'
	export default {
		name:'Count',
		data() {
			return {
				n:1, //用户选择的数字
				
			}
		},
		computed:{
			 ...mapState('countAbout',['sum','school','subject']),
			 ...mapState('personAbout',['personList']),
 
			 ...mapGetters('countAbout',['bigSum'])
 
 
 
		},
		methods: {
			//借助mapMutations生成对应的方法，方法中会调用commit去联系mutaions
			...mapMutations('countAbout',{increment:'JIA',decrement:'JIAN'}),
 
 
			// incrementOdd(){
			// 		this.$store.dispatch('jiaOdd',this.n)
			// },
			// incrementWait(){
			// 		this.$store.dispatch('jiaWait',this.n)	
			// },
 
			//
			...mapActions('countAbout',{incrementOdd:'jiaOdd',incrementWait:'jiaWait'})
 
		},
		mounted(){
			const x =mapState({he:'sum',xuexiao:'school',xueke:'subject'})
			console.log(x)
		}
	}
</script>
 
<style>
	button{
		margin-left: 5px;
	}
</style>
 

person.vue

<template>
  <div>
    <h1>人员列表</h1>
    <h3 style="color:blue">上方组件的求和为{{sum}}</h3>
    <input type="text" placeholder="请输入名字" v-model="name">
    <button @click="add">添加</button>
    <ul>
        <li v-for="p in personList" :key="p.id">{{p.name}}</li>
        
    </ul>
        
  </div>
</template>
 
<script>
import { nanoid } from 'nanoid'
 
export default {
    name:'Person',
    data(){
        return{
            name:''
        }
    },
    computed:{
        personList(){
            return this.$store.state.personAbout.personList
        },
        sum(){
            return this.$store.state.countAbout.sum
        }
    },
    methods:{
        add(){
            const personObj={id:nanoid(),name:this.name}
            this.$store.commit('personAbout/ADD_PERSON',personObj)
            this.name=''
            
        }
    }
}
