我正在从头开始创建自己的评论系统。评论本身是从数据库中的那些动态生成的，对于每个评论，我附加一个回复textarea和按钮，供用户发布对某人评论的回复。
问题在于，当我点击回复链接时，它会为每个评论打开一个回复框，而不仅仅是用户希望回复的评论。
HTML：
<a class="comment-reply">Reply</a>
<!--REPLY BOX -->
<div class="reply-box clearfix">
<?php if($signed_in) { ?>
<!-- reply input textarea -->
<div class="container">
<form id="reply-form">
<textarea id="reply" rows="1" placeholder="Your reply here..."></textarea>
<p><input id="reply-btn" type="submit" class="btn btn-primary floatL" value="Post reply" /></p>
</form>
</div>
<?php } ?>
</div>
和jQuery：
<script>
$(document).ready(function(e) {
//hide reply box on page load
$('.reply-box').hide();
//show each individual reply box on click
$('.comment-reply').click(function() {
//$('.reply-box').stop().slideToggle("fast"); /* This opens all div */
$(this).next('.reply-box').stop().slideToggle("fast"); /* This doesn't work at all */
});
});
</script>
我做错了什么？
修改
好的，这是完整的HTML：

不介意造型，我仍然是原型
编辑 - 添加了渲染页面

也许以下代码会有所帮助，我使用当前元素的parentElement，然后获取同一组中的textarea。附加单击处理程序时，我使用带有注释 - 容器的div，并仅在单击时附加锚点（.on函数中的第二个参数）。
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.10.2.js"></script>
</head>
<body>
<div class="comments-container">
<div class="comment">
Comment1
<a href="#">comment</a><br>
<textarea></textarea>
</div>
<div class="comment">
Comment2
<a href="#">comment</a><br>
<textarea></textarea>
</div>
<div class="comment">
Comment3
<a href="#">comment</a><br>
<textarea></textarea>
</div>
</div>
<script>
$("textarea").hide();
$(".comments-container").on("click","a",function(e){
e.preventDefault();
$("textarea").hide();
$(this.parentElement.getElementsByTagName("textarea")[0])
.stop().slideToggle("fast");
});
</script>
</body>
</html>

问题是.reply-box在DOM中与点击的.comment-reply链接不同（即不是兄弟）。如果您看到documentation for .click，您会看到它只搜索兄弟。
我想你想要.parents(".media").next(".reply-box")
