ruby-on-rails - :confirm is generating two confirm messages

Question

我正在使用以下代码:

<li class="dele-yaniv"><%= link_to "delete", order, :method => :delete,
                                     :confirm => "You sure you want to delete " +order.name+"?",
                                     :title => order.name %></li>

当用户单击删除链接时，他会收到一条确认消息“您确定要删除吗？”

点击确定后，另一条消息再次出现，第二行“复选框阻止此页面创建其他对话框

发生了什么事？

Answer 1

您应该只对变量进行插值。我认为问题是您如何传递 :confirm 选项的结果。您可以通过将变量括在 #{ 和 } 中来将变量包含在引号内，如下所示:

<li class="dele-yaniv">
  <%= link_to "delete", order, :method => :delete,
                               :confirm => "You sure you want to delete #{order.name}?",
                               :title => order.name %>
</li>
