Dynamic divs not working in IE11

Dynamic divs not working in IE11

We're displaying data based on parameters in the URL string and it's working fine in Chrome and Firefox, but not in IE11. Here's what we have. 

  1. CSS
  2. .welcomeNew{
  3. display:none;
  4. }
  5. .welcomeBack{
  6. display:none;
  7. }

  9. iQuery
  10. $(document).ready(function() {
  11. var visitor = new URL(location);
  12. var newvisitor = visitor.searchParams.get("v")
  13. if (newvisitor == '0') {
  14.                   $('.welcomeNew').show();
  15.   $('.welcomeBack').hide();
  16. }
  17. else {
  18.                   $('.welcomeBack').show();
  19.   $('.welcomeNew').hide();
  20. }
  21. });

  23. HTML
  24. <h1 class="welcomeBack">Welcome back</h1>
  25. <h1 class="welcomeNew">Welcome here</h1>
