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
//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 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(); } 3,服务器端处理 /// 其实这三种方法还是建议用第二种方法! 以上就是cookie的三种操作方法的内容,更多相关文章请关注PHP中文网(www.php.cn)!
/// 将点击的值存放到Cookie中
///
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);
}
///
/// 将点击的值从Cookie中取出
///
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;
}
///
/// 移除cookie中指定的键,若是最后一个键则移除这个cookie
///
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);
}
}
