如何在Rails 3.1中显示控制器特定的javascript? [英] How to display controller specific javascript in rails 3.1?
问题描述
我的资产文件夹结构如下
I have my assets folder structure like this
assets
javascripts
products
--product.js
--productValidate.js
store
--store.js
我希望仅当调用产品控制器中的操作时才将project.js和projectValidate.js作为资产管道的一部分添加到application.js中，而当调用商店控制器中的操作时要将store.js添加到资产管道中.如何在Rails 3.1中实现此目标?
I want the project.js and projectValidate.js to be added in my application.js as a part of asset pipe-lining only when actions in product controller is called and store.js when actions in store controller is called. How can i achieve this in rails 3.1?
推荐答案
正如Rahul所述，application.js是预编译的，并且对于每个操作都是相同的. 因此，它不依赖于特定的控制器. Application.js应包含所有(或大部分)操作所需的javascript.
As Rahul already mentioned, application.js is precompiled and the same for every action. So it does not depend on a particular controller. Application.js should contain the javascript you need for all (or most) of your actions.
但是，您可以使用嵌套布局扩展应用程序布局.让我们假设以下结构:
However, you may expand your application layout with nested layouts. Let us assume the following structure:
... app/view/layouts/application.html.erb ...
<html>
<head>
<%= javascript_include_tag 'application' %>
<%= yield :javascripts %>
<%= stylesheet_link_tag 'application' %>
<%= yield :stylesheets %>
</head>
<body>
<%= yield %>
</body>
</html>
和一个:
... app/view/layouts/products.html.erb ...
<% content_for :stylesheets do %>
<%= stylesheet_include_tag 'products' %>
<% end %>
<% content_for :javascripts do %>
<%= javascript_include_tag 'products' %>
<% end %>
<%= render :template => 'layouts/application' %>
因此，您只需要在products-files中添加/要求您的样式表和javascript. 注意，这里的所有代码都应阅读为伪代码，我没有对其进行测试.
So you just have to add/require your stylesheets and javascripts in the products-files. Notice, all code here should be read as pseudo-code, I did not test it.
