Question

我在/public/javascripts/test下的文件夹中有一堆Javascripts，我希望尽可能少地使用javascript_include_tag将它们包含在我的布局中。

目前我使用javascript_include_tag有25行代码，有没有办法更好地做到这一点？另外我不能使用javascript_include_tag :all :recursive，因为在其他目录中有一些我不想包含的JS文件。

感谢您的帮助。

更新所以现在我有一个javascript.rb初始化程序，它有这一行代码（非常长）：

ActionView::Helpers::AssetTagHelper.register_javascript_expansion :syntax_highlight => Dir["#{Rails.root.to_s}/public/javascripts/sh/*.js"].each {|js| js.gsub!("#{Rails.root.to_s}/public/javascripts/",'')}

现在我的布局中有以下内容：

<%= javascript_include_tag :syntax_highlight %>

现在，当我渲染页面时，我得到以下内容：

<script src="/javascripts/sh/shAutoloader.js?1278089940" type="text/javascript"></script> 
<script src="/javascripts/sh/shBrushAppleScript.js?1278089940" type="text/javascript"></script>

但由于某些原因，这一切都不起作用？是什么给了什么？

Answer 1

可能还有更好的解决方案，但这仍然可以解决问题：

Dir["#{Rails.root.to_s}/public/javascripts/test/*.js"].each {|js_file| javascript_include_tag js_file }

Answer 2

试试这个

在config / application.rb

中

取消注释此行

config.action_view.javascript_expansions[:defaults] = %w(javascript1.js javascript2.js)

并添加文件的名称，例如javascrip1.js和javascrip2t.js等。

然后在views / layouts中添加此行

<%= javascript_include_tag :defaults %>

Vlad Khomich的答案也很棒，也会奏效。

Answer 3

考虑到你包含了这么多js文件，我假设你要在公共目录下包含所有js文件。如果是这种情况，您可以更改javascript_include_tag，如下所示，它将帮助您将整个文件作为生产文件提供，从而节省大量请求：

javascript_include_tag :all, :recursive => true, :cache => true

如果您想单独处理测试文件，可以register_javascript_expansion，:defaults，也可以使用Vlad Khomich的答案代码。

# config/init/javascript.rb
ActionView::Helpers::AssetTagHelper.register_javascript_expansion :tests => [array_of_js_paths_from_previous_answer]

# application.html.erb
<%= javascript_include_tag :tests, :cache => :tests %>

使用javascript_include_tag和一个充满JS的子文件夹
