如何将下拉菜单更改为单选按钮? [英] How do I change a dropdown menu to radio buttons?

问题描述

我有一个带有选择列表的下拉菜单:

I have a drop-down menu with a list of choices:

select_tag(:"answers[#{question.question_no}]", options_for_select( [['Agree Strongly', 7], ['Agree Mostly', 6], ['Agree Somewhat', 5], ['Neither Agree Nor Disagree', 4], ['Disagree Somewhat', 3], ['Disagree Mostly', 2], ['Disagree Strongly', 1]] ))

我希望它显示七个单选按钮.这怎么可能.如果有的话?

I would like it so that it displays seven radio buttons instead. How is this possible. if at all?

推荐答案

   <%- [['Agree Strongly', 7],
       ['Agree Mostly', 6],
       ['Agree Somewhat', 5],
       ['Neither Agree Nor   Disagree', 4],
       ['Disagree Somewhat', 3],
       ['Disagree Mostly', 2],
       ['Disagree Strongly', 1]].each do |button| %>
      <%= radio_button_tag :name, button.first, :value => button.last %>
    <% end %>

甚至更好地列出控制器

...控制器

  def some_action
  @choices = [['Agree Strongly', 7],
           ['Agree Mostly', 6],
           ['Agree Somewhat', 5],
           ['Neither Agree Nor   Disagree', 4],
           ['Disagree Somewhat', 3],
           ['Disagree Mostly', 2],
           ['Disagree Strongly', 1]]
  end
