评论回复不能由JS正确显示

Question

为了防止在提交表单后刷新页面，我想添加return false; 还有刷新此页面的默认浏览器行为问题。

---

但是如果我添加return false;或e.preventDefault（）;任何评论的回复显示只有最后/顶部/新评论重复和刷新后它显示原始评论。不仅删除评论显示加载器持续。

现在我认为我的问题是我的html结构或JavaScript。

index.php的HTML：

<div class="content"><comment>

   <div class="post'.$id.'">
   //here main comment goes on
   </div>

     <div class="reply'.$id.'" id="replynext"><ul>
     //here reply goes on
     </ul></div>

<comment></div>

Reply.php的HTML：

<div class="reply'.$id.'" id="replynext"><ul>
//new reply goes here
</ul></div>

JS回复而不返回false;：

var inputAuthor = $("#author");
var inputComment = $("#comment");
var inputReplycom = $(".replycom");
var inputImg = $("#img");
var inputUrl = $("#url");
var inputTutid = $("#tutid");
var inputparent_id = $("#parent_id");
var commentList = $(".content > comment");

function updateReplybox(){
var tutid = inputTutid.attr("value");
    //just for the fade effect
$.ajax({
type: "POST", url: "reply.php", data: "action=update&tutid="+ tutid,
complete: function(data){
var RID   =  $(this).attr('class').replace('reply','');
$(".reply"+RID).append(data.responseText);
$(".reply"+RID).fadeIn(2000);
    }
});
}

    //on submit reply
$(".repfrm").click(function(){
error.fadeOut();
var author = inputAuthor.attr("value");
var url = inputUrl.attr("value");
var img = inputImg.attr("value");
var replycom = inputReplycom.attr("value");
var parent_id = inputparent_id.attr("value");
var tutid = inputTutid.attr("value");

        $(".loader").fadeIn(400).html('<br><img src="loaders.gif" align="absmiddle">&nbsp;<span class="loading">Loading Update...</span>');
        //send the post to submit.php
        $.ajax({
        type: "POST", 
        url: "reply.php", 
        data: "action=insert&author="+ author + "&replycom="+ replycom + "&url="+ url + "&img="+ img + "&parent_id="+ parent_id + "&tutid="+ tutid,

            complete: function(data){
            error.fadeOut();
            $(".reply"+RID).append(data.responseText);
            updateReplybox();
            //reactivate the send button
}
});
error_message();
    //we prevent the refresh of the page after submitting the form
});
