使用 JavaScript 在 Rails 3 中加载远程表单
我是 Rails 和 javascript 的新手。这可能是一个非常简单的问题，但我仍然无法弄清楚。 目标是，我有一个按钮链接，单击该按钮后应在同一页面上加载地址表单。代码的链接是
<%= link_to "添加地址", new_address_path, {:class => “按钮”}，{：远程=>正确}%>
地址文件“addresses/new.html.erb”是：
<div id="newaddr">
<%= render :partial => 'form', :local => @address %>
</div>
表单是“addresses/_form.html.erb”：
<%= form_for(@address, :remote => true) do |f| %>
<%= render 'shared/error_messages', :object => f.object %>
<%= f.text_field :line_1 %>
<%= f.submit %>
<% end %>
javascript 文件“addresses/new.js.erb”：
$('#newaddr').append("<%= escape_javaScript(render 'form', :local => @address) %>");
addresses_controller 文件中的新方法是：
def new
@title = "Add Address"
@address = Address.new
respond_to do |format|
format.js
end
end
但它不起作用。我在这里缺少什么吗？
谢谢！
I am new in rails and javascript. This may be a very simple question but I am still unable to figure it out.
The goal is that, I have a link to button that when clicked should load a address form on the same page. The link to code is
<%= link_to "Add Address", new_address_path, {:class => "button"}, {:remote => true} %>
The address file "addresses/new.html.erb" is:
<div id="newaddr">
<%= render :partial => 'form', :local => @address %>
</div>
The form is "addresses/_form.html.erb":
<%= form_for(@address, :remote => true) do |f| %>
<%= render 'shared/error_messages', :object => f.object %>
<%= f.text_field :line_1 %>
<%= f.submit %>
<% end %>
The javascript file "addresses/new.js.erb":
$('#newaddr').append("<%= escape_javaScript(render 'form', :local => @address) %>");
The new method in addresses_controller file is:
def new
@title = "Add Address"
@address = Address.new
respond_to do |format|
format.js
end
end
But it doesn't work. Is there anything I am missing here?
Thanks!

您收到的错误表明您的链接正在作为普通 HTML 链接执行，而不是 js。你的控制器方法只接受js，所以它返回406，不可接受。
最明显的原因是
rails.jsjavascript 未包含在您的application.html.erb中。通常添加以下行就足够了：或者，如果这不起作用，请明确执行：
希望这会有所帮助。
The error you get indicates that your link is being executed as a normal HTML link, not a js. Your controller method only accepts the js, so it returns the 406, not acceptable.
The most obvious reason for this is that the
rails.jsjavascript is not included in yourapplication.html.erb. Normally adding the following line is sufficient:or, if that does not work, do it explicitly:
Hope this helps.
更改您的 new.js.erb 文件：
