有没有人知道用于在cookie中存储信息的强大类?
我只想写类似的东西:
var cookieStorage = new cookieStorage(100); // 100 - time to store data
var apple = {size:10, color:'red',weight:100};
cookieStorage.set('MyApple',apple);
var restoredApple = cookieStorage.get('MyApple');
我的实施(没有时间存储)
var cookieStorage = {
set: function (key, value) {
$.cookie(key, $.toJSON(value));
},
get: function (key) {
var json = $.cookie(key);
return $.parseJSON(json);
}
}
Here是Cookie插件

您可以使用JSON库来实现此目的。您可以在此处下载JSON:https://github.com/douglascrockford/JSON-js
我为你创建了一个简单的例子。如果你想缩短它,你可以使用JQuery-cookie。
function setCookie(){
var current = new Array();
var user = new Object();
user.FirstName = "Robby";
user.LastName = "Shaw";
current.push(user); //The test value
var exdate=new Date();
exdate.setDate(exdate.getDate()+5); //Expire in 5 days
var cname = "test"; //cookie name
var value = JSON.stringify(current); //Parse the array
document.cookie=cname+ "=" +escape(value)+ ";expires="+exdate.toGMTString();
}
function getCookie(){
var current = new Array();
if (document.cookie.length>0){
c_start=document.cookie.indexOf("test=");
if (c_start!=-1)
{
c_start=c_start + c_name.length+1
c_end=document.cookie.indexOf(";",c_start)
if (c_end==-1) c_end=document.cookie.length
current = JSON.parse(unescape(document.cookie.substring(c_start,c_end)));
alert(current[0].FirstName+","+current[0].LastName);
}
}
}
