How Can I Reliably Detect Browser Language Preferences in JavaScript, Especially in IE and Firefox?

Detecting Browser Language Preference in JavaScript

Understanding the browser language preference is crucial for providing tailored user experiences. However, detecting this preference using JavaScript can be challenging. In this discussion, we'll explore how to access the language setting from IE and Firefox despite the browser UI not directly reflecting it in the navigator.language property.

IE Browser:

To detect the language preference in IE, we cannot rely on navigator.language. Instead, we need to access the HTTP 'Accept-Language' header using a third-party script. This script can be hosted on Google App Engine or a similar platform. Here's an example:

$.ajax({ 
    url: "http://ajaxhttpheaders.appspot.com", 
    dataType: 'jsonp', 
    success: function(headers) {
        language = headers['Accept-Language'];
        nowDoSomethingWithIt(language);
    }
});

This script will return the Accept-Language header in a JSONP response, which can be parsed to obtain the preferred language.

Firefox Browser:

Unfortunately, there is currently no direct way to access the language preference set in Firefox using navigator.language. However, you can use the same third-party script as above to access the HTTP 'Accept-Language' header.
