1. 设置 cookie 封装
function setCookie(key, value, expires){
let now = new Date();
now.setDate(now.getDate()+expires);
document.cookie = `${key} = ${value}; expires= ${now.toUTCString()}`;
}
2. 提取 cookie 封装
function getCookie(){
let obj = {};
let cookies = document.cookie.split('; ');
cookies.forEach(r => {
let kv = r.split('=');
let key = kv[0];
let val = kv[1];
obj[key] = val;
});
if(key){return obj[key]}
return obj
}
3. 删除 cookie 封装
function removeCookie(key){
setCookie(key, null, -1)
}
