vuex结合localStoarge实现对数据的存储

import Vue from 'vue';

const state = {
    title: []
};

 export const getters = {
    title(state){
      if(state.title.length==0){
        state.title=JSON.parse(localStorage.getItem('title'))
      }
      return state.title;
    }
};

 export const actions = {
    getTitle(commit){
      Vue.http.get(‘api’,data).then(function(res){
        commit('get_title',name)
      })
    }
 };

 export const mutations = {
      get_title(state,name){
        state.title = name;
        localStorage.setItem('title',JSON.stringify(state.title))
      }
 };

 export default {
   state,
   getters,
   actions,
   mutations
 }
