jQuery toggle elements with class in parent div only

问题

I've been beating my head against my desk for the last two days over this one. I'm making an app that displays info from a db, the title/link, thumbnail, and time saved wrapped in an unordered list, like so: http://blog.madebycraig.com/images/full.jpg
What I'm trying to do is have a minimize button on the element, toggling the thumbnail and time saved on and off: http://blog.madebycraig.com/images/minimized.jpg
I can accomplish this, but it's all or nothing. I click one minimize button, and everything goes. How can I contain it to just toggle items with a certain class name that are children of the div that the minimize button is in? I've tried .parent(), .child(), .next(), .prev(). I've thrown everything at it that I know. Now I turn to you, kind sirs (or madams). What am I doing wrong? Here's the ul I'm trying to run it on.

echo'
<li class="bookmarkContainer">
<a href="'.$row['url'].'" class="toggle"><img class="thumb" src="images/placeholder.png" /></a>
<div class="title"><a href="'.$row['url'].'" class="bookmrk" target="_blank">'.$row['title'].'</a></div>
<div class="dt toggle">'.relativeTime($row['dt']).'</div><br />
<a class="collapse" href="#">hide</a>
<a class="delete" href="?delete='.$row['id'].'" id="'.$row['id'].'">Delete Bookmark</a>
</li>';

You can do it using .closest() and .find() like this:

$(".collapse").click(function() {
  $(this).closest('.bookmarkContainer').find('.toggle').toggle();
});

If you have lots of these, or they are changing via ajax (seems like a search-resulty thing), use .live() or .delegate() like this:

$(".collapse").live('click', function() {
  $(this).closest('.bookmarkContainer').find('.toggle').toggle();
});
//or...
$("#ulID").delegate('.collapse', 'click', function() {
  $(this).closest('.bookmarkContainer').find('.toggle').toggle();
});
