Hi, Ricardo,
Got your point, but, suppose we have the following situation (which led me
to test parent elements using $().parent() and $().parents()):
<div class="grandparent">
<div class="parent">
<div class="child">
Am I in DOM?
</div>
</div>
</div>
var grandparent = $('div.grandparent');
var child = $('div.child');
$('div.parent').remove();
What would be the result of child.get(0).parentNode ? Sorry not to test it
right now, but I'm not at home, and can't test it right now...
Thanx!
Diogo
