I need a short basename function (one-liner ?) for Javascript:

basename(/a/folder/file.a.ext) -> file.a

basename(/a/folder/file.ext) -> file

basename(/a/folder/file) -> file

That should strip the path and any extension.

Update:
For dot at the beginning would be nice to treat as special files

basename(/a/folder/.file.a.ext) -> .file.a

basename(/a/folder/.file.ext) -> .file

basename(/a/folder/.file) -> .file # empty is Ok

basename(/a/folder/.fil) -> .fil  # empty is Ok

basename(/a/folder/.file..a..) -> # does'nt matter

function baseName(str)

{

   var base = new String(str).substring(str.lastIndexOf('/') + 1); 

    if(base.lastIndexOf(.) != -1)       

        base = base.substring(0, base.lastIndexOf(.));

   return base;

}

If you can have both / and as separators, you have to change the code to add one more line
