Php jquery本地滚动问题

我有一个为用户定制评论部分的社交网络。用户还可以回复评论。每个评论都有一个“回复”按钮，按下该按钮时，使用jquery显示一个新的文本框结构

它的语法和逻辑有点冗长，所以我对可能出现的问题有点茫然（它根本不起作用。我也用尽了故障排除方法）

以下是评论和回复的代码：

<div id="x_comment_box">
                <form name="x_comment_form" method="post" action="Project-X.php">
                    <textarea name="comment_body" class="round_10px defaulted">Leave a comment about "Name of Video"...</textarea>
                    <input type="submit" name="x_submit" value="Submit" class="post"/>
                </form>
            </div>
            <?php   
            $query = "SELECT * FROM `x_comments` WHERE `status` = 'active' ORDER BY `date` DESC, `time` DESC LIMIT 10";
            $request = mysql_query($query,$connection) or die(mysql_error());
            while($result = mysql_fetch_array($request)) {
            $webcast_poster = new User($result['userID']);
            $body = $result['commentBody'];
            $date = $result['date'];
            $time = $result['time'];
            $comment_id = $result['id'];
            ?>

                <div class="comment_structure_future_webcast_x clearfix">

请留下关于“视频名称”的评论。。。
你能进一步解释一下什么不起作用吗？你能详细说明一下问题吗？另外，也许我看得不够仔细，但我没有看到任何jQuery？我的错误。jQuery现在已经存在。问题是，当点击回复按钮时，框没有按应有的方式出现
<script type="text/javascript">
$(document).ready( function() {
    $('#Comments').localScroll({ offset:{top:-40,left:0} });
    $("a.reply_link").click( function() {
        $("#"+$(this).attr('name')).fadeIn('slow');
    });

    $(".respond_nevermind a").click( function(event) {
        event.preventDefault();
        var reply_box = document.getElementById($(this).attr('href'));
        $(reply_box).css('display','none');

        var reply_textarea = document.getElementById($(this).attr('href')+"_textarea");
        $(reply_textarea).val('');
    });
});
</script>
