jQuery: Set cookie for two domains
提问by Artpixler
I want to set a cookie to a domain, but it should be available for a sub domain as well.
我想为域设置 cookie，但它也应该可用于子域。
e.g. www.mydomain.com and sub.mydomain.com
例如 www.mydomain.com 和 sub.mydomain.com
When I set the cookie to the main domain it doesn't exist for the subdomain.
当我将 cookie 设置为主域时，它不存在于子域中。
I use jQuery cookie Plugin: https://code.google.com/p/cookies/wiki/Documentation
我使用 jQuery cookie 插件：https: //code.google.com/p/cookies/wiki/Documentation
My idea was to store it for both domains, have a look at the code:
我的想法是为两个域存储它，看看代码：
var newOptions = {
domain: 'sub.mydomain.com',
secure: true
}
jaaulde.utils.cookies.set('name', 'value');
jaaulde.utils.cookies.set('name', 'value', newOptions );
What do I wrong?
我怎么了？

Cash2m is correct, you should be able to specify a . to reach your subdomains:
Cash2m 是正确的，您应该能够指定一个 . 访问您的子域：
$.cookie('key', 'value', { domain: '.mydomain.com' });

Well, if you want to extend it to the domain and not only a specific subdomain, just use
好吧，如果您想将其扩展到域而不仅仅是特定的子域，只需使用
domain : 'mydomain.com'
instead of :
代替 ：
domain: 'sub.mydomain.com'
