我想看看是否有人可以帮助我解决这个问题。我想看看如何在我的页面中插入评论并当场更新，但问题是，我不知道该怎么做。我试图看起来像这样的网站，我不知道如何让它正常工作，因为即使查看源代码，它似乎也没有帮助。这就是我到目前为止所拥有的。

<!DOCTYPE html>
<!-- 
this is a comment, the above indicates the formal document type 
(like what a file extension does, but as part of the document)
-->
<html>

<head>
  <!-- the head section is things that aren't visible on the page, like the title -->
  <title>Da Blog</title>

  <!-- we'll put lots more in here later -->

  <link rel="stylesheet" type="text/css" href="jquery.css" />
  <script src="http://code.jquery.com/jquery.js"></script>
  <link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css">
</head>

<body>
  <!-- the body is where the visible stuff goes -->

与将HTMLElement添加到DOM Tree类似，Comment也是一个节点（nodeType 8）并且将以相同的方式工作。用来document.createComment新建一个，你可以修改数据属性来改变它的内容。
