【基于node.js+express的web开发备忘】--技术分享（TShare）站点-布局（layout）
express 4.2.0 默认不适用layout的模版布局，视图模版ejs+bootstrap(模版样式)可以使用include引入页面模版：
<%include xxx/xxx/模版文件名 %>，其中ejs的文件后缀可带可不带。
另外，express 4.2.0已经去除文件存放位置的限制，可以放到工程的任何自定义的路径下，采用"."向上一级目录引用。
其中views/index.ejs为主视图文件，主要内容：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<title><%= title %> - TShare</title>
<link rel='stylesheet' href='/myall/css/style.css' />
<script type="text/javascript" src="/jquery/jquery-1.7.2.min.js"></script>
<!- 外部组件引用--bootstrap 页面样式 ->
<link rel='stylesheet' href='/bootstrap/css/bootstrap.css' />
<link rel="stylesheet" href="/bootstrap/css/bootstrap-responsive.css" >
<script type="text/javascript" src="/bootstrap/js/bootstrap.js"></script>
<!- 外部组件引用--markitup 文本编辑器 ->

<link rel="stylesheet" type="text/css" href="/MarkitUp/markitup/sets/default/style.css">
