Question

我正在为我的控制器使用标准脚手架：

# 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

我的应用程序布局文件：

<!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>

单击删除链接时，将显示节目视图，而不是确认或删除。很困惑。

的 EDIT2： 的我添加了＆lt;％= javascript_include_tag'应用'％＆gt;到我的application.html.erb文件，该记录被删除但我现在收到一个错误加载页面，以及服务器中的以下内容：

编辑： 这是来自服务器的响应。我以为删除是DELETE而不是GET？

Answer 1

我有类似的问题。我的解决方案是：

1-确保application.js包含以下内容

//= require jquery
//= require jquery_ujs

2-确保application.js包含在我的应用程序布局中

= javascript_include_tag 'application'

3-删除旧版本的JQuery我也在我的应用程序布局中包含（这个让我感到困惑的一点）

希望有所帮助！

Answer 2

设置confirm或delete只会设置一些data- *属性。您可以在页面上使用这些属性来创建所需的行为。没有任何JavaScript，它只是一个简单的旧链接。

jquery-ujs库提供此功能。
