JavaScript在Rails中未作为响应执行

Question

I have a form that creates messages in my view, and I want the list of messages on the same page to update on create. 我有一个在我的视图中创建消息的表单，并且我希望同一页面上的消息列表在创建时进行更新。 So I am using Ajax. 所以我正在使用Ajax。 The return from the create action seems to be html, and not just the js script, and the script is not executing. 从create动作返回的似乎是html，而不仅仅是js脚本，并且该脚本未执行。 (I tried putting in an alert function to test). （我尝试放入警报功能进行测试）。

Instead the script is appended to the end of the response. 而是将脚本附加到响应的末尾。 What am I doing wrong? 我究竟做错了什么？

My controller action: 我的控制器动作：

def create
    @order = Order.find(params[:order_id])
    @customer = @order.customer
    @message = current_user.messages.create(
      body: message_params[:body],
      order_id: @order.id
      )
    respond_to do |format|
      if @message.save
        format.html { redirect_to @message, notice: 'Message was successfully created.' }
        format.js
      end
    end

create.js.haml: create.js.haml：

%script(type="text/javascript")
  $("#messages").append("<p>Hello</p>");

My form 我的表格

= simple_form_for :message, remote: true, url: order_messages_path(@order), method: :post do |f|
  = f.error_notification
  = f.hidden_field :customer_id, value: @order.customer.id
  .form-inputs
    = f.text_field :body
  .form-actions
    = f.button :submit

And the response comes back with the full html: 并返回完整的html：

  (...)
  </head>
  <body>
    <nav>
      (...)
    </nav>
    <script type='text/javascript'>
      $("#messages").append("<p>Hello</p>");
      console.log("Hello");
    </script>
    </div>
  </body>
</html>

Server response: 服务器响应：

Answer 1

First of all, I think the %script(type="text/javascript") is not necessary. 首先，我认为％script（type =“ text / javascript”）是不必要的。 Try removing it and putting 尝试将其删除并放入

format.js { render "create.js.haml" }

The #messages element exists, right? #messages元素存在，对吗？
