regex - Pull a Specific File name from URL with JavaScript/Jquery

Question

Im trying to pull a specific file name from a URL, Ive looked at the posts but there isnt anything that answers the question that I need. I need a Javascript or Jquery that can pull just the file name ("Test1") from:

You can get url information like that from the window.location object. Try this out

params = window.location.search.split(/&/)

for (var i=0; i < params.length; i++) {
  if (params[i].match(/^??RootFolder=/)){
    paths = params[i].split(///);
    filename = paths[paths.length-1];
    break;
  }
};
