sessionStorage和localStorage的范围 [英] Scope of sessionStorage and localStorage

问题描述

我在sessionStorage和localStorage上阅读了一些文档，但我不明白范围是什么：域名，特定页面？

I read some documentation on sessionStorage and localStorage, but I don't understand what the scope is: the domain, a specific page?

例如，如果我有以下页面：

For example, if I have the following pages:

http：/ /example.com/products.aspx?productID=1

http://example.com/products.aspx?productID=2

http://example.com/services.aspx?serviceID=3

如果我在上面的每个页面上运行（idvalue是查询字符串中的值）：

And if on each of the above pages I run (with idvalue being the value in the querystring):

localStorage.setItem('ID',idvalue);

我最终会存储3个不同的值，或者值是否会相互覆盖？

Am I going to end up with 3 different values stored, or are the values going to overwrite each other?

推荐答案

这些值将会相互覆盖。无论路径如何，每个密钥名对对于协议和域都是唯一的。

The values are going to overwrite each other. Each key-name pair is unique for a protocol and domain, regardless of the paths.

可以通过 document.domain更改受影响的域 property。

The affected domain can be changed via the document.domain property.

• sub.example.com - > example.com 是可能的（子域名）


• sub.example.com - > other.example.com 是不可能的

• sub.example.com -> example.com is possible (subdomain)
• sub.example.com -> other.example.com is not possible
