This javascript will get the whole path and the file name however the idea is to retrieve the file name + extension and its parent folder so it returns this:

/thisfolder/thanks.html

var url = "www.example/get/thisfolder/thanks.html";
var path = url.substring(url.indexOf('/')+1, url.lastIndexOf('.'));
alert(path)

Using .split(), you can select the last 2 elements and join them together after:

var url = "www.example./get/thisfolder/thanks.html";
var path = url.split('/').slice(-2).join('/'); 
alert(path);

You could split by /:

var parts = url.split("/");
var filename = parts.pop();
var parent = parts.pop();

Here is an alternative using array:

var paths = url.split("/");
var path = paths[paths.length - 2] + "/" + paths[paths.length - 1];
