jQuery/PHP: sliding up even if its not :last

I want to slide up #FriendRequests (a bar) if its the last friend request the user is answering on (confirm/ignore).

When you answer confirm/ignore, it sends ajax call and on success i made this:

$('#FriendRequests:last').slideUp('slow');

But my problem is now, that even if its not the last friend request you are answering on the #FriendRequests bar is sliding up.

How should i do this, so it slides up if its the last request the user is answering on? and what code/information do you need from me, please comment, so i will provide what you need in order to help me

Thank you

My code right now:

<div class="FriendRequests" style=" font-weight: bold; background: #283b43; border-bottom: 1px dashed #719dab;">
<img src="images/NewFriend_small.png" style="float: left; margin-left: 25px; margin-right: 10px;">
Friend Requests

function MeYouFriendNB(confirm, uID, fID, bID){
 var c = confirm ? 'confirm' : 'ignore';
    $.ajax({ 
       type: "POST",
       url: "misc/AddFriend.php",
    data: {
    mode: 'ajax',
            friend: c,
            uID: uID,
            fID: fID,
            bID: bID
            },
       success: function(msg){
            $('#friend'+fID).slideUp('slow');
        }
     });
}

EDIT based on your comments:

Sounds like maybe the slideUp() for #FriendRequests should trigger after the final friend has been hidden.

If so, I'd still add a class to the friend elements and do this:

success: function(msg){
    $('#friend'+fID).slideUp('slow', function() {
        if( $('div.friend:visible').length == 0 ) {
             $('#FriendRequests').slideUp('slow');
        }
    });
}

try this working ex:

just add a common class to all ur friendID div.

This all depends on your code...this is just an assumption. post your code

I think you're misunderstanding :last. Last just returns the last element that matches.

You want something like

// remove row
if ( $("#FriendRequests li").length == 0 ) {
    $('#FriendRequests').slideUp('slow');
} 

again...depends on your code
