第八讲、Vue3.x中的模块化以及封装Storage实现todo

一、 localStorage里面的方法

localStorage.setItem(key,value)

localStorage.getItem(key)

localStorage.removeItem(key);

localStorage.clear();

二、封装localStorage
1、新建models/storage.js

var storage={

    set(key,value){

        localStorage.setItem(key, JSON.stringify(value));
    },
    get(key){

        return JSON.parse(localStorage.getItem(key));
    },remove(key){
        localStorage.removeItem(key);
    }

}

export default storage;

2、引入

import storage from './model/storage.js';
