【问题描述】：
这是我的代码，使用 PHP 和 jquery。这是我的网站http://bubblewschat.com。我遇到的部分问题是代码显示在已发布的网站上。如何删除它，是否可以严格使用 html 构建聊天室？
<div id="page-wrap">
<h2>Let's talk</h2>
<p id="name-area"></p>
<div id="chat-wrap">
<div id="chat-area"></div>
</div>
<form id="send-message-area">
<p>Your message: </p>
<textarea id="sendie" maxlength="100"></textarea>
</form>

【问题讨论】：
-
能否正确格式化您的代码？我们现在根本无法阅读/理解它。
-
您的代码有很多问题。其中之一是您在最后一个
</div>之后忘记了<script type="text/javascript">。建议清理它并发布jsfiddle 链接。
