URL mapping for switcher of multilanguage site

Heyhey,

I set up a multilingual site with the Brad Good method. Worked all well but when I tried to implement his code for URL mapping of the language switcher (i.e., switching language and arriving at the corresponding site in the other language), I got stuck. It just doesn't want to work and I can't figure out why. Can anybody help?

This is the code for the URL mapping:

Quote

<script>
  $(function() {
    switch (window.location.pathname) {
    case '/en/about':
      $(".language a.lang-en").attr("href", "/en/about");
      $(".language a.lang-de").attr("href", "/de/uebersicht");
      break;
    case '/de/uebersicht':
      $(".language a.lang-en").attr("href", "/en/about");
      $(".language a.lang-de").attr("href", "/de/uebersicht");
      break;
    case '/en/services':
      $(".language a.lang-en").attr("href", "/en/services");
      $(".language a.lang-de").attr("href", "/de/leistungen");
      break;
    case '/de/leistungen':
      $(".language a.lang-en").attr("href", "/en/services");
      $(".language a.lang-de").attr("href", "/de/leistungen");
      break;
    case '/en/bio-contact':
      $(".language a.lang-en").attr("href", "/en/bio-contact");
      $(".language a.lang-de").attr("href", "/de/ueber-mich-kontakt");
      break;
    case '/de/ueber-mich-kontakt':
      $(".language a.lang-en").attr("href", "/en/bio-contact");
      $(".language a.lang-de").attr("href", "/de/ueber-mich-kontakt");
      break;
                                  }
});
</script>

ahh so easy in the end. Didn't think about that, thanks heaps!!
