jQuery：

$.cookie(\'cookieName\', \'cookieValue\')  //存入值
$.cookie("cookieName")//取出值

js:

document.cookie = "cookieName="+=cookieValeu;
var cookie_value = getCookie(cookie_name);

java:

//获取cookie
Cookie []cookies=request.getCookies();
String cookieName="myCookie";
if(cookies != null){
    for(Cookie cookie : cookies) {
        if(cookie.getName().equals(cookieName)) {
          return cookie.getValue();
         }
     }
}

//存储
String cookieName="myCookie";
String cookieValue="cookieValue";
Cookie myCookie=new Cookie(cookiename,(Object)cookieValue);
myCookie.setmaxAge(60*60*24);//一天
respose.addCookie(myCookie);
