How to get client's system “Region and Language” settings on server?

问题

Is there any way to get format settings (country from "Formats" tab on "Region and Language" popup in Windows) in JavaScript so I can pass it to server in cookie? (big target - display dates in correct format on MVC 4 server-side)

In IE9 I can use navigator.UserLanguage (also correct language is passed in Accept-Language http header).

But in Chrome and FF navigator.UserLanguage is undefined, navigator.language and Accept-Language returns browser's interface language.

回答1:

It is not possible for JS or anything else to access this setting, however there is the HTTP_ACCEPT_LANGUAGE language property which can be accessed on the server. For example with PHP you can do:

 echo $_SERVER['HTTP_ACCEPT_LANGUAGE'];

which will echo something like en-US. In most cases this will probably be the users prefered language, so why not use it?
