JavaScript for detecting browser language preference

I want to detect the language of the browser that is entering my site, if it’s En or Fr. So I can redirect to the En page or the other page.
Also, can I detect mobile language?

Solutions/Answers:

Solution 1:

Try this script to get your browser language

<script type="text/javascript">
var userLang = navigator.language || navigator.userLanguage; 
alert ("The language is: " + userLang);
</script>

Cheers

Solution 2:

The “JavaScript” way:

var lang = navigator.language || navigator.userLanguage; //no ?s necessary

Really you should be doing language detection on the server, but if it’s absolutely necessary to know/use via JavaScript, it can be gotten.
