1，jquery.cookie.js
这一篇文章已经写的很详细了：

2，原生js操作cookie
jquery.cookie.js一般会出现cookie不兼容问题就要用原生的js了
<script language=javascript> //获得coolie 的值function cookie(name){ var cookieArray=document.cookie.split("; "); //得到分割的cookie名值对
var cookie=new Object();
for (var i=0;i<cookieArray.length;i++){
var arr=cookieArray[i].split("="); //将名和值分开
if(arr[0]==name)return unescape(arr[1]); //如果是指定的cookie，则返回它的值
} return "";
} function delCookie(name)//删除cookie
{ document.cookie = name+"=;expires="+(new Date(0)).toGMTString();
}function getCookie(objName){//获取指定名称的cookie的值
var arrStr = document.cookie.split("; ");
for(var i = 0;i < arrStr.length;i ++){
var temp = arrStr[i].split("=");
if(temp[0] == objName) return unescape(temp[1]);
}
}function addCookie(objName,objValue,objHours){ //添加cookie
var str = objName + "=" + escape(objValue);
if(objHours > 0){ //为时不设定过期时间，浏览器关闭时cookie自动消失
var date = new Date();
var ms = objHours*3600*1000;
date.setTime(date.getTime() + ms);
str += "; expires=" + date.toGMTString();
}
document.cookie = str;
}function SetCookie(name,value)//两个参数，一个是cookie的名子，一个是值
{ var Days = 30; //此 cookie 将被保存 30 天
var exp = new Date(); //new Date("December 31, 9998");
exp.setTime(exp.getTime() + Days*24*60*60*1000);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}function getCookie(name)//取cookies函数
{ var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
if(arr != null) return unescape(arr[2]); return null;
}function delCookie(name)//删除cookie
{ var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval=getCookie(name);
if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString();
}</script>3，服务器端处理
/// <summary>
/// 将点击的值存放到Cookie中
/// </summary>
private void SetCookieValue(HttpContext context, string dic, string cookieName, string keyName)
{
HttpCookie cookie = new HttpCookie(cookieName);//初使化并设置Cookie的名称
if (context.Request.Cookies[cookieName] != null)
{
cookie = context.Request.Cookies[cookieName];
if (cookie.Values.Count > 0 && cookie.Values.GetValues(keyName) != null && cookie.Values.GetValues(keyName).Length > 0)
{
Remove(cookieName, keyName);
}
}
TimeSpan ts = new TimeSpan(0, 3, 0, 0, 0);//过期时间为3小时
cookie.Expires = DateTime.Now.Add(ts);//设置过期时间
cookie.Values.Add(keyName, dic);
context.Response.AppendCookie(cookie);
//NCookieUtil.SetCookie(keyName, dic);
}
/// <summary>
/// 将点击的值从Cookie中取出
/// </summary>
public string GetClickValue(HttpContext context, string cookieName, string keyName)
{
string userName = "";
if (context.Request.Cookies[cookieName] != null)
{
if (context.Request.Cookies[cookieName][keyName] != null)
{
userName = context.Request.Cookies[cookieName][keyName].ToString();
}
}
//userName = NCookieUtil.GetCookie(keyName);
return userName;
}
/// <summary>
/// 移除cookie中指定的键，若是最后一个键则移除这个cookie
/// </summary>
public static void Remove(string cookieName, string keyName)
{
HttpCookie cookie = HttpContext.Current.Request.Cookies[cookieName];
if (cookie != null)
{
if (cookie.Values.Count > 0)
{
if (cookie.Values.Count == 1)
{
//若是最后一个键则移除这个cookie,否则会多出一个空值
cookie.Values.Remove(HttpUtility.UrlEncode(keyName));
cookie.Expires = DateTime.Now.AddDays(-1);
}
else
{
cookie.Values.Remove(HttpUtility.UrlEncode(keyName));
}
HttpContext.Current.Response.Cookies.Add(cookie);
}
}
}
其实这三种方法还是建议用第二种方法！
