[jQuery] how to delete div individually

[Xmode]

I need to know how to delete div individually, after some research I
couldn't find nothing concrete. I did a comment system using jquery
and it's working like a charm, but now when I logon as admin... I am
displaying a link in the corner of the comment that says "delete"

what i want to do is click delete
jquery sends delete.php via ajax i know how to do this
then div dissapears....

the only problem I'm having is getting the right div into the
javascript function, I am very new in jquery and I had a code working
with mootools, but now I want all my project to run on jquery alone...

Here is sample code for delete using mootools...

Comment format:
<div id="comment_436"><hr /><a href="javascript:void(0)"
onClick="Comment.delete('436')" style="float: right">delete</a><a
href="http://192.168.0.5/flog/xmode";>xmode</a> @ 28/09/2008
03:02:53<br />asdadad<br /></div>
<div id="comment_437"><hr /><a href="javascript:void(0)"
onClick="Comment.delete('437')" style="float: right">delete</a><a
href="http://192.168.0.5/flog/xmode";>xmode</a> @ 28/09/2008
03:05:26<br />sdadad<br /></div>

Java:
var cmsComment = new Class({
        delete: function(id){
                new Ajax('http://192.168.0.5/flog/delete.php',{ data:
'id='+id }).request();
                new Fx.Style('comment_'+id, 'opacity',{ onComplete: function(){
                        $('comment_'+id).setStyle('display', 'none');
                } }).start(1,0);
        }
});
var Comment = new cmsComment();

how you can see in the function I passed an id to the java which then
was passed to delete.php and then div was set to dissapear...
is there a simple way of doing this with jquery also??
