如何在JS Rails响应中包含HTML？ [英] How do I include HTML in a JS Rails response?
问题描述
我有一个响应HTML和JS（AJAX）查询的FooController：
I have a FooController that responds to HTML and JS (AJAX) queries:
# 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
支持它的模板：
# app/views/layouts/foo.html.erb:
<html>...<%= yield %>...</html>
# app/views/layouts/foo.json.erb:
<%= yield %>
还有一个我想在其中渲染局部图像的AJAX模板：
And an AJAX template in which I want to render a partial:
# app/views/foo/bar.js.erb:
dojo.byID('some_div').innerHTML = "<%= escape_javascript(render(:partial => 'some/partial')) %>";
如果JS模板中仅包含普通的旧JS（例如 alert（ 'hi'）; ），它使用了我的JS模板。但是，当我放入render（：partial）时，它将使整个响应都使用HTML模板，这意味着它不再是有效的JS。
If the JS template just has plain old JS in it (like alert('hi');), it uses my JS template. When I put in the render(:partial), though, it makes the whole response use the HTML template, which means it's no longer valid JS.
可能的解决方案是将功能用于布局：
A possible solution is to use a function for the layout:
class FooController < ApplicationController
layout :choose_layout
...
private
def choose_layout
return nil if request.xhr?
'foo'
end
end
但是我的版本应该起作用！为什么不呢？
But my version should work! Why doesn't it?
推荐答案
最新的 Railscast涵盖了这个主题（使用jQuery）。
我不太清楚您可能在哪里出了问题，但这是Railscast的一个片段，可以很好地呈现部分片段：
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:
// 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();
您要将JavaScript存储在哪里？您是否有要保留的Application.js？如果是这样，您是否在javascript_include_tag中的应用程序之前包含 dojo？
Where are you storing your Javascript? Do you have an Application.js that you're keeping things in? If so, are you including "dojo" before "application" in your javascript_include_tag?
