web前端核心技术如何使用js操作获取和设置cookie

//创建cookie

function setCookie(name, value, expires, path, domain, secure) {

var cookieText = encodeURIComponent(name) + ‘=’ + encodeURIComponent(value);

if (expires instanceof Date) {

cookieText += ‘; expires=’ + expires;

}

if (path) {

cookieText += ‘; expires=’ + expires;

}

if (domain) {

cookieText += ‘; domain=’ + domain;

}

if (secure) {

cookieText += ‘; secure’;

}

document.cookie = cookieText;

}



//获取cookie

function getCookie(name) {

var cookieName = encodeURIComponent(name) + ‘=’;

var cookieStart = document.cookie.indexOf(cookieName);

var cookieValue = null;

if (cookieStart > -1) {

var cookieEnd = document.cookie.indexOf(‘;’, cookieStart);

if (cookieEnd == -1) {

cookieEnd = document.cookie.length;

}
