C# 讀寫Cookies
public string CookieValue
{
get{ return this.txtCookies.text;}
set{ this.txtCookies.text=value.ToString();}
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
CookieValue=GetCookies();
if (GetCookies() != CookieValue)
SetCookies(CookieValue);
}
private void SetCookies(string cookieValue)
{
string key = {CookieName}+ ("_" + {用戶ID或是其它整型}).GetHashCode().ToString(); //GetHashCode()，做僞裝處理
HttpCookie cookie = new HttpCookie(key, cookieValue)
cookie.Expires = DateTime.Now.AddYears(1);
cookie.Domain = ".blog.51cto.com";
Response.Cookies.Add(cookie);
}
private string GetCookies()
{
string key = {CookieName}+ ("_" + {用戶ID或是其它整型}).GetHashCode().ToString();
if (Request.Cookies[key] != null)
{
return Request.Cookies[key].Value == null ? "1" : Request.Cookies[key].Value.ToString();
}
return "{默認值}";
}
Javascript 讀寫Cookies
function FunctionName(cookieValue) {
if (getcookie(colorKey) != cookieValue ) {
addcookie(colorKey, cookieValue , (365 * 24));
}
}
function addcookie(name, value, expireHours) {
var cookieString = name + "=" + escape(value);
//判斷是否設置過期時間
if (expireHours > 0) {
var date = new Date();
date.setTime(date.getTime + expireHours * 3600 * 1000);
cookieString = cookieString + "; expire=" + date.toGMTString();
}
document.cookie = cookieString;
}
function getcookie(name) {
var strcookie = document.cookie;
var arrcookie = strcookie.split("; ");
for (var i = 0; i < arrcookie.length; i++) {
var arr = arrcookie[i].split("=");
if (arr[0] == name) return arr[1];
}
return "{默認值}";
}
