jquery实现cookie登录记住用户名密码问题，只需在页面写上相应js方法后台不用做任何处理，下次登录就能记住用户名和密码

先来介绍关于jquery读取cookie方法

example $.cookie(’the_cookie’, ‘the_value’);
设置cookie的值
example $.cookie(’the_cookie’, ‘the_value’, {expires: 7, path: ‘/’, domain: ‘jquery.com’, secure: true});
新建一个cookie 包括有效期 路径 域名等
example $.cookie(’the_cookie’, ‘the_value’);
新建cookie
example $.cookie(’the_cookie’, null);
删除一个cookie

看一个dz遍历cookie方法

分割的数组的处理

function getcookie(name) {
var cookie_start = document.cookie.indexof(name);
var cookie_end = document.cookie.indexof(";", cookie_start);
return cookie_start == -1 ? "" : unescape(document.cookie.substring(cookie_start + name.length + 1, (cookie_end > cookie_start ? cookie_end : document.cookie.length)));
}
function setcookie(cookiename, cookievalue, seconds, path, domain, secure) {
var expires = new date();
expires.settime(expires.gettime() + seconds);
document.cookie = escape(cookiename) + "=" + escape(cookievalue)
+ (expires ? "; expires=" + expires.togmtstring() : "")
+ (path ? "; path=" + path : "/")
+ (domain ? "; domain=" + domain : "")
+ (secure ? "; secure" : "");
}

好了费话说了一大堆了现在我们进来正题

public static void showcookies()
        {
            int16 i;
            httpcookiecollection cookies = system.web.httpcontext.current.request.cookies;
            for (i = 0; i < cookies.count; i++)
            {
                httpcookie cookie = cookies.get(i);
                system.web.httpcontext.current.response.write("cookie名称: " + cookie.name + "
");
                system.web.httpcontext.current.response.write("值=: " + cookie.value + "
");
                system.web.httpcontext.current.response.write("expires期限: " + cookie.expires.tostring() + "
");
                system.web.httpcontext.current.response.write("

---

");
                // system.web.httpcontext.current.response.write ("domain网域:" + cookie.domain  + "
");
                // system.web.httpcontext.current.response.write ("path路径:" + cookie.path + "
");
                //system.web.httpcontext.current.response.write ("secure保密:" + cookie.secure + "
");
            }
            system.web.httpcontext.current.response.write("共有 " + cookies.count + " 个cookie
");
        }
public static void deleteallcookies()
        {
            int16 i;
            httpcookiecollection cookies = system.web.httpcontext.current.request.cookies;
            for (i = 0; i < cookies.count; i++)
            {
                httpcookie cookie = cookies.get(i);
                cookie.value = "";
                cookie.expires = datetime.now.adddays(-365);
                system.web.httpcontext.current.response.cookies.set(cookie);

            }
            system.web.httpcontext.current.response.write("共有 " + cookies.count + " 个cookie被删除
");

            /* cookies.clear(); */
        }
        public static void clearallcookies()
        {
            int16 i;
            httpcookiecollection cookies = system.web.httpcontext.current.request.cookies;
            for (i = 0; i < cookies.count; i++)
            {
                httpcookie cookie = cookies.get(i);
                cookie.value = "";
                system.web.httpcontext.current.response.cookies.set(cookie);
            }
            system.web.httpcontext.current.response.write("共有 " + cookies.count + " 个cookie被清空
");
        }
