1，jquery.cookie.js
這一篇文章已經寫的很詳細了：

2，原生js操作cookie
jquery.cookie.js一般會出現cookie不兼容問題就要用原生的js了
<script language=javascript>
//獲得coolie 的值
function cookie(name){
var cookieArray=document.cookie.split(
"; "
);
//得到分割的cookie名值對
var cookie=
new
Object();
for
(var i=
0
;i<cookieArray.length;i++){
var arr=cookieArray[i].split(
"="
);
//將名和值分開
if
(arr[
0
]==name)
return
unescape(arr[
1
]);
//如果是指定的cookie，則返回它的值
}
return
""
;
}
function delCookie(name)
//刪除cookie
{
document.cookie = name+
"=;expires="
+(
new
Date(
0
)).toGMTString();
}
function getCookie(objName){
//獲取指定名稱的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
){
//為時不設定過期時間，瀏覽器關閉時cookie自動消失
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)
//兩個參數，一個是cookie的名子，一個是值
{
var Days =
30
;
//此 cookie 將被保存 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函數
{
var arr = document.cookie.match(
new
RegExp(
"(^| )"
+name+
"=([^;]*)(;|$)"
));
if
(arr !=
null
)
return
unescape(arr[
2
]);
return
null
;
}
function delCookie(name)
//刪除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，服務器端處理
/// <summary>
/// 將點擊的值存放到Cookie中
/// </summary>
private void SetCookieValue(HttpContext context, string dic, string cookieName, string keyName)
{
HttpCookie cookie = new HttpCookie(cookieName);//初使化並設置Cookie的名稱
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);//過期時間為3小時
cookie.Expires = DateTime.Now.Add(ts);//設置過期時間
cookie.Values.Add(keyName, dic);
context.Response.AppendCookie(cookie);
//NCookieUtil.SetCookie(keyName, dic);
}
/// <summary>
/// 將點擊的值從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中指定的鍵，若是最后一個鍵則移除這個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)
{
//若是最后一個鍵則移除這個cookie,否則會多出一個空值
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);
}
}
}
其實這三種方法還是建議用第二種方法！
