I use this to simulate the (non-existing) :last-letter CSS pseudoclass, e. g. to insert a
tombstone
Show archive.org snapshot
at the end of an article:
findLastLeaf = ($container) ->
$children = $container.children()
if $children.length == 0
$container
else
$lastChild = $children.last()
$lastContent = $container.contents().filter(->
# Only return nodes that are either elements or non-empty text nodes
@nodeType == 1 || (@nodeType == 3 && _.strip(@nodeValue) != '')
).last()
if $lastContent.get(0) == $lastChild.get(0)
findLastLeaf($lastChild)
else
$container
Please note that you can't simply say $container.descendants.last() or something similar, since jQuery is ignorant of text nodes.
