Capture Browser language preference using javascript

[Jyoti Aggarwal]

Hi I need to capture Browser language preference using javascript. I have tried few thing like

 
alert(navigator.browserLanguage);
alert(navigator.userLanguage);
alert(navigator.systemLanguage);

but no matter what is the language selected in the browser it always returns [en-us]. Please help

  var lang ="NA";
  if (navigator.userLanguage)
    lang = navigator.userLanguage;
  else if (navigator.language)
    lang = navigator.language;

It might read the system and not browser

You might have to look at the data sent to the server.
