application.haml 和 application.html.haml 的区别？

Question

很多天以来，我一直在努力理解为什么像这样一个简单的 link :

link_to 'My Link', my_path(format: :js), remote: true

总是返回完整的 HTML 文档，而不是执行位于我的 file.js.erb 中的 javascript :

alert('hello world')

[...]

经过几个小时的调试，我找到了原因：

当我重命名我的主布局文件如时：application.haml它呈现完整的HTML文档：

Started GET "/my_path/2.js" for 127.0.0.1 at 2016-03-05 12:28:20 +0100
Processing by MyController#show as JS
  Rendered my_path/show.js.erb within layouts/application (0.1ms)
  Rendered layouts/_sidebar.html.erb (18.9ms)
  Rendered layouts/_headbar.haml (0.5ms)
  Rendered layouts/_flash_messages.html.haml (0.2ms)
  Rendered layouts/_footer.html.erb (0.1ms)
Completed 200 OK in 102ms (Views: 59.3ms | ActiveRecord: 2.9ms)

当我重命名我的主布局文件如时：application.html.haml它正确执行javascript并运行我的hello world popup :

Started GET "/my_path/8.js" for 127.0.0.1 at 2016-03-05 12:28:34 +0100
Processing by MyController#show as JS
  Rendered my_path/show.js.erb (0.1ms)
Completed 200 OK in 24ms (Views: 21.8ms | ActiveRecord: 0.4ms)

为什么 javascript 行为会根据我布局的不同文件名而有所不同？

Answer 1

正如 BroiSatse 所说：

This is not javascript behaviour, it is how rails searches for templates. First it search for <action_name>.<templating-engine> files, then for <action_name>.<format><templateing-engine>. So when you have generic template without the format, it will be taken for all the formats.
