javascript - Dynamic Nested Form link_to_add called twice

Question

I am using ryan bates nested_form gem to dynamically add some nested field to a form.

e.g.

<%= f.fields_for :phones do |phone_form| %>
<%= phone_form.text_field :phone_number %>
<% end %>
<%= f.link_to_add "Add a phone", :phones %></p>

Everything works, except TWO empty fields are added every time the link is clicked.

I placed a breakpoint on $('form a.add_nested_fields').live('click', function() and see it is called twice...

I am using chrome on a mac

看看你的标题。你会看到这里有两次：

<script src="/assets/nested_form.js?body=1" type="text/javascript"></script>

只需删除第二个引用（可能在您的 application.html.erb 中），它就会起作用。

对于那些使用 rails 4 / turbolinks 并且没有找到包含两次 nested_form.js 的人，请尝试从 application.js 中删除 turbolinks。一旦我这样做并退回服务器，这个问题就解决了。

您可能已经加载了两次嵌套的表单 js 文件

检查是否加载了多个 js 文件，如果您在多个项目中工作，请确保清除浏览器缓存
