[jQuery] Quick check over these few lines ?

[Harri]

Hi,
I've used a few jquery things before, but I haven't a clue when it
comes to javascript, so I've mainly just modified variables here and
there. This is my first attempt at actually writing something, and
well.....its not working :P

Im trying to send an ajax post to an external file, which simply
returns 'Complete' after updating the db. My html gives me an ul, with
li elemnts, representing names of comics. Anyway heres my code, Id
just like someone with more experience than me to tell me if im doing
anything wrong:

                $(function() {
                        $("li").each(function(){
                                $.post("ajax_parser_update.php", {query: 
$(this).val()},
                                function (data) {
                                        $(this).append(data);
                                });
                                return false;
                });
                });

Thanks,
Harrison
