jQUERY get the parent folder of url

Question

I want to use Ajax to load an xml file. This file is located into another folder of the root directory.

1. How do I get the root directory path with jQuery?
2. How do I move to the parent directory of the current path with jQuery?

window.location.hostname

var string1 = "../example/index.html";
var string2 = string1.replace(string1.split("/").pop(),"");

string2=../example/
