模板引擎之jade 学习

jade 模板引擎在node express 开发中有较多的使用，首先我们看一个简单的使用jade 生成的html 页面的标签代码：

doctype html
html(lang="en")
  head
    title= pageTitle
    script(type='text/javascript').
      if (foo) {
         bar(1 + 5)
      }
  body
    h1 Jade - node template engine
    #container.col
      if youAreUsingJade
        p You are amazing
      else
        p Get on it!
      p.
        Jade is a terse and simple
        templating language with a
        strong focus on performance
        and powerful features.

相应生成的html 代码如下:

<!DOCTYPE html>
<html lang="en">
  <head>
    <title>Jade</title>
    <script type="text/javascript">
      if (foo) {
        bar(1 + 5)
      }
    </script>
  </head>
  <body>
    <h1>Jade - node template engine</h1>
    <div id="container" class="col">
      <p>You are amazing</p>
      <p>Jade is a terse and simple
         templating language with a
         strong focus on performance
         and powerful features.</p>
    </div>
  </body>
</html>

我们可以看到使用jade 模板可以简化我们的代码.
