jquery cookie不工作 - 相同的域不同的文件夹 [英] jquery cookie not working - same domain different folder

问题描述

我在子目录中有一个html页面：

I have a html page in a sub directory:

http://mydomain.com/subDir/mag.html

该文件使用$ .cookie设置cookie，然后加载主索引页面，如下所示：

That file sets a cookie using $.cookie, then loads the main index page like so:

$.cookie("something",value);
alert( $.cookie("something") );  // test code: this shows the cookie correctly
window.open("../index.html","_self");

但是当我这样做的时候，我松开了cookie（显示为undefined）。如果我把mag.html放在与index.html相同的目录级别，它工作。

But when I do that, I loose the cookie (shows as undefined). If I put mag.html on the same directory level as index.html, it works.

我可以解决这个问题，但是想知道为什么会这样，

I can work around this but was wondering why this is so, since the domain hasn't changed.

推荐答案

一个路径没有访问另一个Cookie的权限，除非它是一个较低级别的路径

One path doesn't have access to another's cookies, unless it is a lower level path (that is, closer to the 'core').

您的cookie设置在 subDir 中。您必须将其设置为主索引文件的路径，以便能够访问此Cookie。

Your cookie is set in subDir. You have to set it to the path of the main index file so to be able to access this cookie there.

为了设置自定义路径，您必须传递第三个参数到 $。cookie（）方法，这是一个配置对象。

In order to set a custom path, you will have to pass a third argument to the $.cookie() method, which is a configuration object.

code> $。cookie（something，value，{path：'/'}）;

So: $.cookie("something", value, { path: '/' });
