This question already has an answer here:

I have been trying to detect the browser language preference using JavaScript.

If I set the browser language in IE in Tools>Internet Options>General>Languages, how do I read this value using JavaScript?

Same problem for Firefox. I'm not able to detect the setting for tools>options>content>languages using navigator.language.

Using navigator.userLanguage , it detects the setting done thru Start>ControlPanel>RegionalandLanguageOptions>Regional Options tab.

I have tested with navigator.browserLanguage and navigator.systemLanguage but neither returns the value for the first setting(Tools>InternetOptions>General>Languages)

I found a link which discusses this in detail, but the question remains unanswered :(

I had the same problem, and I wrote the following front-end only library that wraps up the code for multiple browsers. It's not much code, but nice to not have to copy and paste the same code across multiple websites.

Get it: acceptedlanguages.js

Use it:

<script src="acceptedlanguages.js"></script>
<script type="text/javascript">
  console.log('Accepted Languages:  ' + acceptedlanguages.accepted);
</script>

It always returns an array, ordered by users preference. In Safari & IE the array is always single length. In FF and Chrome it may be more than one language.

Dan Singerman's answer has an issue that the header fetched has to be used right away, due to the asynchronous nature of jQuery's ajax. However, with his google app server, I wrote the following, such that the header is set as part of the initial set up and can be used at later time.

<html>
<head>
<script>

    var bLocale='raw'; // can be used at any other place

    function processHeaders(headers){
        bLocale=headers['Accept-Language'];
        comma=bLocale.indexOf(',');
        if(comma>0) bLocale=bLocale.substring(0, comma);
    }

</script>

<script src="jquery-1.11.0.js"></script>

<script type="application/javascript" src="http://ajaxhttpheaders.appspot.com?callback=processHeaders"></script>

</head>
<body>

<h1 id="bLocale">Should be the browser locale here</h1>

</body>

<script>

    $("#bLocale").text(bLocale);

</script>
</html>
