使用Javascript删除会话cookie [英] Delete session cookies by using Javascript

问题描述

我正在开发删除会话cookie的功能

I am working on a function to delete the session cookies

以下是源代码：

<script language="javascript">
window.onload = function ()
{
   /* $.cookie('!lithiumSSO:tomtom.stage', null);
    $.cookie('LiSESSIONID', null);*/
        delete_cookie('LiSESSIONID');
         delete_cookie('!lithiumSSO:tomtom.stage');

};
function delete_cookie ( cookie_name )
    {
        var cookie_date = new Date ( );  // current date & time
        cookie_date.setTime ( cookie_date.getTime() - 1 );
        document.cookie = cookie_name += "=; expires=" + cookie_date.toGMTString();
        alert('name:' +cookie_name);
        jQuery.cookie('LiSESSIONID', null); //Try to using jQuery
    }

我可以设置一个弹出窗口显示名称：LiSESSIONID =; expires = Wed，02 Feb 2011 10:56:52 GMT。这比落后一小时。但是，当我使用firecookies时，我看到这个cookie仍然存在：

I can set got a pop up window displays name:LiSESSIONID=; expires=Wed, 02 Feb 2011 10:56:52 GMT. Which is one hour behind. However, when I use firecookies, i saw this cookie still exists:

LiSESSIONID

HttpOnly

有谁知道为什么我不能杀死cookie？ jQuery函数状态表示undefined甚至我加载函数

Does anyone have an idea why i can not kill the cookies? jQuery function state said undefined even I load the function

谢谢

推荐答案

原因是因为设置了HttpOnly标志。这意味着只有服务器端代码才能修改此cookie。

The reason is because the HttpOnly flag is set. This means that only the server side code can modify this cookie.
