jQuery to get part of a url and apply it to the end of an existing link

Solution:1

You can get the path from JavaScript’s built-in Locationwindow.location.pathname.split('/')[1] will give you the first segment of the path, depending on your url this will be either “fr”, “de” or “en”

Solution:2

This is what worked for me using jQuery

$(document).ready(function () {
var trail = window.location.href.substr(window.location.href.lastIndexOf("/")+1); 
$(".en-link").find('a').attr('href', $(".en-link").find('a').attr('href') + trail);
$(".fr-link").find('a').attr('href', $(".fr-link").find('a').attr('href') + trail); 
  }); 

But also need to counter for subpages for press and media sections:

jQuery(function ($) {
  $(document).ready(function () {
var trail = window.location.href.substr(window.location.href.lastIndexOf("/")+1);  
  var trailSub = window.location.href.substr(window.location.href.lastIndexOf("/")-5);  
    if (window.location.href.indexOf("press") != -1) {
$(".en-link").find('a').attr('href', $(".en-link").find('a').attr('href') + trailSub);
$(".fr-link").find('a').attr('href', $(".fr-link").find('a').attr('href') + trailSub); 
    }
    else if (window.location.href.indexOf("media") != -1) {
$(".en-link").find('a').attr('href', $(".en-link").find('a').attr('href') + trailSub);
$(".fr-link").find('a').attr('href', $(".fr-link").find('a').attr('href') + trailSub); 
    }
    else {
      $(".en-link").find('a').attr('href', $(".en-link").find('a').attr('href') + trail);
$(".fr-link").find('a').attr('href', $(".fr-link").find('a').attr('href') + trail); 
    }
  });
});
