刷新之后还是显示刚刚选择的城市localStorage.city

import Vue from "vue";
import Vuex from "vuex";

Vue.use(Vuex);
let defaultCity = "北京";
2.本地存储赋值给变量
defaultCity = localStorage.city;
export default new Vuex.Store({
  state: {
3.赋值
    cityName: defaultCity,
  },
  mutations: {
    changeCity(state, city) {
      state.cityName = city;
1.点击之后把城市传值到本地存储
      localStorage.city = city;
    },
  },
  actions: {},
  modules: {},
});
