jQueryでHTMLのツリーを編集する

結局使わなかったコードをお焚き上げ。
<link>タグの追加と指定したタグ削除をjQueryで行うコードです。
リストが6件以下だったらタグ消してCSS1読み込んで、違ったらCSS2読み込む、といった流れです。

<script type="text/javascript">
    $(function() {
    if (6 >= $('#foo_list').children().length ) {
        // リストが6件以下

        // CSS1を読込む
        $('head').append('<link rel="stylesheet" href="css/style_1.css" media="all" />');

        // タグの削除
        $('#bar_list').remove();
        $('#hoge_list > label').remove();
    } else {
        // リストが6件以上

        // CSS2を読込む
        $('head').append('<link rel="stylesheet" href="css/style_2.css" media="all" />');
    }
    });
</script>
