Here we are some different types to get last value from array

function RemoveLastDirectoryPartOf(the_url)
{
    var the_arr = the_url.split('/');
    the_arr.pop();
    return( the_arr.join('/') );
}
var res = RemoveLastDirectoryPartOf(window.location.href);
alert(res);

Try this simple method using lastIndexOf() and slice()

url = window.location.href;
url = url.slice(0, url.lastIndexOf('/'));
alert(url);
url = url.slice(0, url.lastIndexOf('/'));
alert(url);
