[jQuery] prevAll() Working in Safari 3 but not Firefox (2 or 3pre Beta)

[Brian DeWitt]

Hello everyone! I've been reading this group's messages for a while
now. Its really helpful and has kept me from having to ask a question.
Until now.

i'm having an issue with some code working in Safari 3 but not in
Firefox 2.0.0.11 and Firefox  3pre Beta (the nightly builds). I have a
file called jsfile.js where i have a good bit of my jQuery code and
another file called htmlfile.html. The jQuery and jsfile files are
linked in the header of htmlfile.html.

The problem i am having is that in Safari 3, the Hide These link in p
class="More" does hide the Stuff div in Safari 3. However in Firefoxes
2 and 3pre it does not.

Following is my HTML:

<td class="StreamBody>
  <a class="hidden_toggle" href="#" target="_blank"
onclick="showHiddenActivitiesLists(this); return false;">the link to
display the Stuff div below</a><br />
  <div class="Meta">
     <div class="time"><a href="some_link" class="secondary">another
link</a>
     </div>
  </div>
  <div class="Stuff" style="display:none">
    <ul class="Music">
       <li class="hidden_activity">a list item</li>
    </ul>
    <p class="More"><a href="#" class="secondary" onclick="$
(this).parent().parent().prevAll('a.hidden_toggle').click(); return
false;">Hide These</a></p>
  </div>
</td>


And now for my javascript:

function showHiddenActivitiesLists(el) {
        $(el).attr('onclick','hideHiddenActivitiesLists(this); return
false;');
        $(el).parents('.StreamBody').children('.StreamStuff').fadeIn(500);
}

function hideHiddenActivitiesLists(el) {
        $(el).attr('onclick','showHiddenActivitiesLists(this); return
false;');
        $(el).parents('.StreamBody').children('.StreamStuff').fadeOut(500);
}

The Hide These onclick should traverse the DOM to the hidden_toggle
and then call the .click() on that link. It does this in Safari 3,
thus re-hiding the Stuff div. However it seems Firefox 2 and 3pre
ignore it.

Any ideas why it would work in Safari 3 and not Firefox?
