Rails 3.0 中的默认 Javascript

Question

在文件 application.html.erb 中，我看到了这一行

  <%= javascript_include_tag :defaults %>

这里的:defaults 是什么意思？它包含哪些 Javascript 文件？

Answer 1

To include the Prototype and Scriptaculous javascript libraries in your application, pass :defaults as the source. When using :defaults, if an application.js file exists in your public javascripts directory, it will be included as well.

Source

换句话说:

• 原型(prototype).js
• controls.js
• 拖放.js
• 效果.js
• rails.js(这个没有在 API 中列出，但是 包含在内)
• application.js 如果存在
