If the input doesn't exist, then wouldn't nothing be returned with $
('input').parent().children(':last') either? It seems to presume the
existence of the input :)
Maybe you meant if the input doesn't have siblings, then nothing is
returned, which is true using nextAll(). Using 'input' with no extra
identifier also means that this would grab all inputs on the page,
which may not be desirable. If the input has an identifier, then you
could also do something like this:
$('input#foo').nextAll(':last').add('input#foo:only-child');
or from your example markup you could do:
$('div input').nextAll(':last').add('div input:only-child'); //fnb it
would grab all inputs in all divs
This will get the last sibling if there is one, and add the input if
it's an only child. Btw, lest somebody think otherwise, I'm not
opposed to traversing up to the parent at all, I just wanted to
continue pursuing the idea without it for fun :)
Rereading the original post makes me question where the emphasis is
"The span might or might not be there, so I would like to just get the
last sibling in a parent". If you're coming from the perspective of
the parent and not the input, then just doing:
$('div').children(':last');
is all you'd really need. Starting from the perspective of the input
you have several choices, which is what makes jQuery so much fun:
there's always more than one way to accomplish some task! It's left to
you to figure out what is optimal (overall or in your particular
situation), and that will have to consider speed, legibility for other
coders, isolation from structure, etc.
