javascript - collection_radio_buttons 自动提交？

Question

有没有办法在点击collection_radio_button时表单会自动提交？

这样他们就不必单击提交按钮，它会自动发生。

<%= simple_form_for(@challenge) do |f| %>
  <%= f.text_field :action %>
    Or choose a featured challenge:
  <%= f.collection_radio_buttons :action, [['Lose 10 Pounds','Lose 10 Pounds'], ['Exercise','Exercise'], ['Quit Smoking','Quit Smoking'], ['Run a 5K','Run a 5K'], ['Meditate','Meditate'], ['Visit Rome','Visit Rome'], ['Read a Chapter','Read a Chapter'], ['Walk 10,000 Steps','Walk 10,000 Steps'], ['Study a Foreign Language','Study a Foriegn Language'], ['No T.V.','No T.V.'], ['Backpack through Europe','Backpack through Europe'], ['Journal','Journal'], ['Go Vegetarian','Go Vegetarian']], :first, :last %>
  <%= f.submit %>
<% end %>

你可以试试这个...

$('input[type=radio]').on('change', function() {
    $(this).closest("form").submit();
});

此处使用了属性选择器，您可能希望将其更改为类或更具体的内容以满足您的需求。
