如何在JS Rails响应中包含HTML？

Question

I have a FooController that responds to HTML and JS (AJAX) queries: 我有一个响应HTML和JS（AJAX）查询的FooController：

# app/controllers/foo_controller.rb:
class FooController < ApplicationController
  layout 'foo'
  def bar
    respond_to do |format|
      format.html # foo/bar.html.erb
      format.js   # foo/bar.js.erb
    end
  end
end

The templates to support it: 支持它的模板：

# app/views/layouts/foo.html.erb:
<html>...<%= yield %>...</html>

# app/views/layouts/foo.json.erb:
<%= yield %>

And an AJAX template in which I want to render a partial: 还有一个我要渲染部分的AJAX模板：

# app/views/foo/bar.js.erb:
dojo.byID('some_div').innerHTML = "<%= escape_javascript(render(:partial => 'some/partial')) %>";

If the JS template just has plain old JS in it (like alert('hi'); ), it uses my JS template. 如果JS模板中只有普通的旧JS（比如alert('hi'); ），它就会使用我的JS模板。 When I put in the render(:partial), though, it makes the whole response use the HTML template, which means it's no longer valid JS. 但是，当我放入render（：partial）时，它会使整个响应使用HTML模板，这意味着它不再是有效的JS。

A possible solution is to use a function for the layout: 一种可能的解决方案是使用布局函数：

class FooController < ApplicationController
  layout :choose_layout
  ...
  private
  def choose_layout
    return nil if request.xhr?
    'foo'
  end
end

But my version should work! 但我的版本应该工作！ Why doesn't it? 为什么不呢？

Answer 1

The most recent Railscast covers this topic (using jQuery) . 最新的Railscast涵盖了这个主题（使用jQuery）。

I'm not quite seeing where you might be going wrong, but here's a snippit from the Railscast that works just fine to render a partial: 我不太明白你可能会出错的地方，但是这里有一个来自Railscast的snippit可以正常工作以呈现部分：

// views/reviews/create.js.erb
$("#new_review").before('<div id="flash_notice"><%= escape_javascript(flash.delete(:notice)) %></div>');
$("#reviews_count").html("<%= pluralize(@review.product.reviews.count, 'Review') %>");
$("#reviews").append("<%= escape_javascript(render(:partial => @review)) %>");
$("#new_review")[0].reset();

Where are you storing your Javascript? 你在哪里存储你的Javascript？ Do you have an Application.js that you're keeping things in? 你有一个Application.js，你有什么东西？ If so, are you including "dojo" before "application" in your javascript_include_tag? 如果是这样，你在javascript_include_tag中的“应用程序”之前是否包含“dojo”？

Answer 2

Try the following; 尝试以下方法;

class FooController < ApplicationController
  layout 'foo'
  def bar
    respond_to do |format|
      format.html
      format.js { render :layout => false }
    end
  end
end

Hope that helps. 希望有所帮助。
