Answer 1

str.substring(str.lastIndexOf("/") + 1)

Though if your URL could contain a query or fragment, you might want to do

var end = str.lastIndexOf("#");
if (end >= 0) { str = str.substring(0, end); }
end = str.lastIndexOf("?");
if (end >= 0) { str = str.substring(0, end); }

first to make sure you have a URL with the path at the end.
