Bootstrap 之 Metronic 模板的学习之路 - （4）源码分析之脚本部分

上篇我们将 body 标签主体部分进行了简单总览，下面看看最后的脚本部门。

页面结尾部分（Javascripts 脚本文件）

我们来看看代码最后的代码，摘取如下：

我们发现，所有脚本都在 之前，而且，源码结尾也没有 标签，这主要是因为以下一些原因：

• 为什么放在最后

HTML 文件的加载都是从上往下执行的，我们一般习惯将一些对显示效果影响不大的脚本文件放到页面的最后进行加载。这样可以减少页面的加载时间。

• 为什么放在 之前

只所以脚本放在 之前，而不是之后，主要是因为：基于规则 %html.content "HEAD|BODY"，HTML 标签的子元素只能是 HEAD BODY，如果在 后再出现 。

• 为什么没有 标签

这个我也忘了哈，好像为了被别的文件包含时，避免出现把文件闭合了这种情况。一下子找不到这方面的说明了，如果哪位大侠知道，麻烦告知。
当然，html5 是支持不闭合标签的。
这儿貌似有一点点说明：http://blog.teamtreehouse.com...
