最近简单了解了前端存储中的cookie、localStorage两种存储方式
localStorage
window.localStorage.setItem('a', 1) (window. 可省略) localStorage.setItem('a', 1) //存储数据 localStorage.getItem('a') //获取数据 localStorage.removeItem('a') //删除指定数据 localStorage.clear( ) //删除全部数据
cookie
document.cookie = 'name=1'; //设置cookie console.log(document.cookie); //获取cookie document.cookie = 'name=1;expires=' + new Date(new Date().setTime(new Date().getTime()-1)).toGMTString(); //通过过期时间删除cookie
