一.定义json

var employees = [

{ "firstName":"Bill" , "lastName":"Gates" },

{ "firstName":"George" , "lastName":"Bush" },

{ "firstName":"Thomas" , "lastName": "Carter" }

];

保存数据到本地

const info = {

name: 'Lee',

age: 20,

id: '001'

};

sessionStorage.setItem('key', JSON.stringify(info));

localStorage.setItem('key', JSON.stringify(info));

本地存储中删除某个保存的数据

sessionStorage.removeItem('key');

localStorage.removeItem('key');

删除所有保存的数据

sessionStorage.clear();

localStorage.clear();

删除对象

object.splice(index,1);

localStorage.setItem("GouWuChe",JSON.stringify(object));
