Is there anyway to detect OS language using javascript?

I need to detect OS language using javascript so I can view my page depending on the language.

I know that we can detect the browser language but that is not enough for me.

I need Operation System language

Thanks in advance

There is no cross-browser way to do this. Internet Explorer supports the following:

• navigator.browserLanguage: browser language
• navigator.systemLanguage: Windows system language
• navigator.userLanguage: Windows user-specific language

But there is no way to access these settings from any other browsers (that I can tell) so don't use them: stick to the standard navigator.language (corresponding to the browser language) if you want to maintain cross-browser functionality. If you do use them you will tie your web site to a specific family of operating systems (i.e. Windows) and a specific browser (i.e. Internet Explorer). Do you really want to do this?

Why is the browser language insufficient for your application?
