Vue官方文档（51）: vuex中模块化的用法

一、定义store

import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

const moduleA = {
    state: () => ({ 
        count1: 1,
        count2: 2
     }),
    mutations: { 
     },
    actions: {  },
    getters: {  }
  }
  
  const moduleB = {
    state: () => ({ 
        count1: 30,
        count2: 40
     }),
    mutations: { 

     },
    actions: {  }
  }
  
  const store2 = new Vuex.Store({
    modules: {
      a: moduleA,
      b: moduleB
    }
  })
export default store2;

二、引入store,此处也可以改成全局引入。并使用。

import store2 from './store/store2'

alert(store2.state.a.count1);
      alert(store2.state.b.count2);
