如果我在页面上有一个下拉列表,其中列出了一些在数据库表中的值。
在下拉菜单旁边,我有一个东西,当点击它时会出现一个文本框。有点像即时编辑。是否可能在那里输入一些值并按回车键,使该值加载到下拉菜单中?

如果选择框是一个Dongle列表,而“Dongle”是一种资源:
在你的 SomethingElseController
中:
@new_dongle = Dongle.new
在你的看法中:
<% remote_form_for @new_dongle do |dongle_form| %>
<%= dongle_form.text_field :name %>
<% end %>
查看remote_form_for 的api文档。如果你想要刚创建对象的id,请查看同一页的link_to_remote
的回调参数。
