提问by overflow

I tried the above method but it is directly deleting without any alert message. What wrong I made. Can any one correct it.
我尝试了上述方法，但它直接删除而没有任何警报消息。我犯了什么错误。任何人都可以纠正它。

Answer for rails 4.1.8 (question doesn't include version)
rails 4.1.8 的答案（问题不包括版本）
and standard resource (also not specified)
和标准资源（也未指定）
//= jquery_ujsmust be included in application.js (possibly missing)- url is
user_path(@user) - specify
:method => :delete(missing) - confirm message within
:data(was good) - destroy methodin controller (not delete)
//= jquery_ujs必须包含在 application.js 中（可能缺少）- 网址是
user_path(@user) - 指定
:method => :delete（缺失） - 确认消息
:data（很好） - 控制器中的销毁方法（不删除）
= link_to t(:delete) , user_path(@user), :method => :delete, :class => "btn btn-danger", :data => {:confirm => t(:are_you_sure )}
= link_to t(:delete), user_path(@user), :method => :delete, :class => "btn btn-danger", :data => {:confirm => t(:are_you_sure )}
The url in the question seems to create a GET, rather than a DELETE method. This may work if :method was specified. imho it is unfortunate that there is no seperate named url helper for this.
问题中的 url 似乎创建了一个 GET，而不是一个 DELETE 方法。如果指定了 :method，这可能会起作用。恕我直言，不幸的是，没有单独的命名 url 助手。

Rails confirmation popup box for destroy action:
用于销毁操作的 Rails 确认弹出框：
<%= link_to 'Show', article_path(article),{:class=>'btn btn-success show_article' }%>
<%= link_to 'Edit', edit_article_path(article),{:class=>'btn btn-warning edit'} %>
<%= link_to 'Destroy', '#', "data-toggle"=>"modal", "data-target" => "#delete-#{article.id}",:class=>'btn btn-danger' %>
<div class="modal fade" id="delete-<%= article.id %>" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">Confirmation Box</button>
</div>
<div class="modal-body">
<p>Are you sure to delete this article</p>
</div>
<div class="modal-footer">
<div class="modal-footer">
<%= link_to 'Delete', article_path(article), method: :delete, :class => 'btn btn-danger' %>
<a href="#" data-dismiss="modal" class="btn btn-warning">Cancel</a>
</div>

I think you should use :method option
<%= link_to 'Delete',url_for(action: :delete,id: @user.id), method: :delete, confirm: "Are you sure?" %>It's probably better to use button (and form) for this kind of action
我认为你应该使用 :method 选项
<%= link_to 'Delete',url_for(action: :delete,id: @user.id), method: :delete, confirm: "Are you sure?" %>使用按钮（和表单）进行此类操作可能会更好

Make sure you have both the jQuery library and the jQuery driver for Rails included. The jquery-railsgem will take care of both of these in the later versions of Rails, from what I know.
确保包含 jQuery 库和 Rails 的 jQuery 驱动程序。据jquery-rails我所知，gem 将在 Rails 的更高版本中处理这两个问题。
Also, for better chances of compatibility with future versions of the jQuery driver, move the :confirmoption outside :dataand let the jquery-railsgem decide what to do with it.
此外，为了更好地与 jQuery 驱动程序的未来版本兼容，请将:confirm选项移到外面:data，让jquery-railsgem 决定如何处理它。
