Question

我正在尝试编写一个小弹出窗口，在我的应用上添加一个新事件，在rails和Ajax上使用ruby。

我已经实现了Ajax并使操作正常工作，但是在responseText中发送的字符串包含的不仅仅是我试图显示的部分。

从服务器端看，由于它显示的输出，它是有意义的：

Started GET "/events/new.html" for 127.0.0.1 at 2018-01-11 21:58:18 +0100
Processing by EventsController#new as HTML
  Rendering events/new.html.erb within layouts/application
  Rendered shared/_error_messages.html.erb (0.4ms)
  Rendered events/new.html.erb within layouts/application (3.9ms)
  Rendered layouts/_rails_default.erb (223.3ms)
  Rendered layouts/_shim.html.erb (0.3ms)
  User Load (0.2ms)  SELECT  "users".* FROM "users" WHERE "users"."id" = ? LIMIT ?  [["id", 1], ["LIMIT", 1]]

  Rendered layouts/_footer.html.erb (0.4ms)
Completed 200 OK in 248ms (Views: 244.1ms | ActiveRecord: 0.2ms)

我可以看到我的服务器从我的事件控制器发送new.html但是我得到了一个错误和一些其他渲染的操作。有谁知道为什么会这样？

我在这里添加了我已实施的代码，以防可能有用

my_app.erb

$(".new_event_button").click(function(){
  console.log("click on add new event");
  // $("body").append("</%= escape_javascript(render 'events/new') %>");

  $("body").append("<div class='new_event_window'></div>");

  var req = new XMLHttpRequest();
  req.open("GET","/events/new.html");
  req.send();

  req.onreadystatechange = function () {
    console.log(req.readyState);
    if (req.readyState === 4) {
        $(".new_event_window").append(req.responseText);
    }
  }
});

事件/ new.html.erb

<h1>New Event</h1>

<div class="row">
  <div class="col-md-6 col-md-offset-3">
    <%= form_for(@event, url: create_event_path) do |f| %>
      <%= render 'shared/error_messages', object: f.object %>

      <%= f.label :title %>
      <%= f.text_field :title, class: 'form-control' %>

      <%= f.submit "Create my account", class: "btn btn-primary" %>

      <%= f.button :cancel, label: "Cancel", class: "btn btn-primary" %>
    <% end %>
  </div>
</div>

最后是我的事件控制器events_controller.erb

class EventsController < ApplicationController

  def new
    @event = Event.new
  end

  def create
  end
end

Answer 1

尝试使用其他方式：

在视图中使用链接

<%= link_to "view", work_path(w), remote: true %>

在控制器上使用响应js

respond_to do |format|
    format.js
end

在view.js.erb

中

$(".new_event_window").html("<%= j(render 'events/new') %>");
$('#myModal').modal('show')

Answer 2

你试试这个：

class EventsController < ApplicationController      
  layout false, only: [:new]

  def new
    @event = Event.new
  end

  def create
  end
end

Ajax responseText呈现多个部分
