el.getParent('.name1.name2') (no space!) will get for You only
elements with both classes, el.getParent('.name1') will get all
elements with class name1, el.getParent(':not(.name2).name1') get You
elements with name1 and not name2. Works also with Sanford version
witch does the same and is better.

I believe for CSS it is in most cases faster to walk inside DOM then
reverse.

Yes, You can, just add it to the selector.
Or You can use .getElements.

var tempId = String('id-'+$time());
elem.set('id', tempId);
