以下是我的观点:
<%= form_tag({ :action => "display"}, :method => "get") do %>
<%= select(:music, :type, MusType::TYPES, {:include_blank => true}) %>
这是模型中的数组常量:
class MusType < ActiveRecord::Base
TYPES = ['Jazz','Rock','Blues']
end
我的选择菜单从数组中提取值。在按下提交按钮后,如何将所选值作为参数传递给控制器?
答案 0 :(得分:0)
你可以做下面的事情。
查看代码
<%= form_tag(:url => {:controller => "mycontroller" :action => "display"}, :method => "get") do %>
<%= select_tag(:music, :type, MusType::TYPES, {:include_blank => true}) %>
<%= submit_tag "Search", :id => 'search' %>
<% end %>
读取mycontroller.rb中的选定值
def display
value = params[:music][:type]
// do something with value
end
