JavaScript在Rails中未作為響應執行
[英]JavaScript not executing as response in Rails
問題描述
我有一個在我的視圖中創建消息的表單，並且我希望同一頁面上的消息列表在創建時進行更新。 所以我正在使用Ajax。 從create動作返回的似乎是html，而不僅僅是js腳本，並且該腳本未執行。 （我嘗試放入警報功能進行測試）。
而是將腳本附加到響應的末尾。 我究竟做錯了什么？
我的控制器動作：
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：
%script(type="text/javascript")
$("#messages").append("<p>Hello</p>");
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
並返回完整的html：
(...)
</head>
<body>
<nav>
(...)
</nav>
<script type='text/javascript'>
$("#messages").append("<p>Hello</p>");
console.log("Hello");
</script>
</div>
</body>
</html>
服務器響應：

首先，我認為％script（type =“ text / javascript”）是不必要的。 嘗試將其刪除並放入
format.js { render "create.js.haml" }
#messages元素存在，對嗎？
