コントローラーに標準の足場を使用しています。

# DELETE /addresses/1
# DELETE /addresses/1.json
def destroy
  @address = Address.find(params[:id])
  @address.destroy

  respond_to do |format|
    format.html { redirect_to addresses_url }
    format.json { head :no_content }
  end
end

私のアプリケーションレイアウトファイル:

<!DOCTYPE html>
<html>
<head>
    <title>DemoRailsApp</title>
    <link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />
    <script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
    <script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script>

    <%= csrf_meta_tags %>
</head>
<body>
  <div data-role="page" data-theme="a" data-fullscreen="true">
    <%= yield %>
  </div>

index.html.erb

<div data-role='header'>
<h1>Addreses</h1>
<%= link_to "Add" , new_address_path, "data-icon"=> "plus" , "class" => "ui-btn-right" %>
</div>

<div class="content" data-role="content">
<ul data-role="listview">
    <% @addresses.each do |address| %> 
    <li>
        <%= link_to address.address1, edit_address_path(address) %>
        <%= link_to 'Destroy', address, confirm: 'Are you sure?', method: :delete, "data-icon" => "delete" %>
    </li>
    <% end %>
</ul>
</div>
</body>
</html>

削除リンクをクリックすると、確認または削除ではなく、ショー ビューが表示されます。非常に混乱。

Edit2: <%= javascript_include_tag 'application' %> を application.html.erb ファイルに追加し、レコードは削除されましたが、ページの読み込み中にエラーが発生し、サーバーから次のメッセージが表示されます:

編集： これはサーバーからの応答です。削除はGETではなくDELETEだと思いましたか？

同様の問題がありました。私の解決策は次のとおりでした：

1- application.js に以下が含まれていることを確認します

//= require jquery
//= require jquery_ujs

2- application.js がアプリケーションのレイアウトに含まれていることを確認します

= javascript_include_tag 'application'

3-アプリケーションレイアウトにも含めていた古いバージョンのJQueryを削除します（これには少し戸惑いました）

それが役立つことを願っています!

いくつかのデータを設定するconfirmか、delete単に設定します-*属性。これらの属性を使用して目的の動作を作成するJavascriptをページに配置するのはあなた次第です。javascriptがなければ、それは単なる古いリンクです。

jquery-ujsライブラリはこれを提供します。
