vuex实现像调用模板方法一样调用Mutations方法

import {mapState,mapMutations} from 'vuex'

<script>

 import store from '@/store'

 import {mapState,mapMutations} from 'vuex'

 export default{

  data(){

   return{


   }

  },

puted:mapState(["num"]),

  methods:mapMutations([//只关注此栏

  

  'jia'

  

  ]),

  store

 }

</script>

<template>

 <div>

  <h3>{{num}}</h3> 

<button @click="jia">+</button><!--此处--> 

<div>

</template>

import Vue from 'vue'

import Vuex from 'vuex'

Vue.use(Vuex)

const state={//状态对象

num:0,

}

const mutations={//触发状态

jian(state){

state.num++

},

}
