rails - 加载另一个页面并替换 div

Question

After some struggling, I managed to make the ajax work:

hello.js.erb:

$("#show_hosts").html("some text");

testQueuesController.rb:

class testQueuesController < ApplicationController

  def index

    @test_queues = testQueue.all

    respond_to do |format|

      format.html

      format.json { render json: @test_queues }

    end

  end

end

The relevant part in the view:

<%= link_to "hello", { :controller => "kashmir_queues", :action => "hello" }, :remote => true %>

Now, this is working, but what I really wanna do, is now load "some text", but to load another view I have named show_hosts.html.erb, how can I do it ?

Answer 1

If I understand your question correctly you want to render the view called show_hosts.html.erb in the HTML tag with the ID show_hosts .

To be able to do this you would need to create a partial for each host - something like _host.html.erb and write the following in hello.js.erb :

$('#show_hosts').html(<%= render partial: 'host', collection: @hosts %>)

Where @hosts is the name I assume you're using for the collection of hosts to be shown in show_hosts.html.erb , though I must admit I'm a bit confused because you use @test_queues in your controller.

For what it's worth (if I remember correctly) you also need to add format.js to your controller in order to render the hello.js.erb template.

In your controller add new action named hello

def hello
 queue = KashmirQueue.find(params[:id]) 
 @test_queues = testQueue.where(:host => queue.host) 
end

move your show.html.erb to a partial like _show.html.erb

then in hello.js.erb write

$("#show_hosts").html('#{escape_javascript(render "show.html.erb")}');
