ruby-on-rails – 如何使用bootstrap的模式显示“删除确认对话框”？不喜欢浏览器的默认值

我正在看这个页面( http://lesseverything.com/blog/archives/2012/07/18/customizing-confirmation-dialog-in-rails/)它显示了一些代码,但我不明白我如何将它实现到我的应用程序.

我使用Rails3.2,Bootstrap.css和JQuery.
有人能告诉我究竟需要做些什么来显示带有bootstrap模式的“删除确认对话框”吗？

更新：

资产/ Java脚本/ application.js中

// This is a manifest file that'll be compiled into application.js,which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory,lib/assets/javascripts,vendor/assets/javascripts,// or vendor/assets/javascripts of plugins,if any,can be referenced here using a relative path.
//
// It's not advisable to add code directly here,but if you do,it'll appear at the bottom of the
// the compiled file.
//

解决方法

The blog entry使用coffeescript.假设您在rails表单中使用：confirm选项,那么您需要覆盖Rails中的默认操作,方法是将以下代码放在资产管道中的< controller> .js.coffee文件中(app / assets / javascript )：

$.rails.allowAction = (link) ->
  return true unless link.attr('data-confirm')
  $.rails.showConfirmDialog(link) # look bellow for implementations
  false # always stops the action since code runs asynchronously

$.rails.confirmed = (link) ->
  link.removeAttr('data-confirm')
  link.trigger('click.rails')

$.rails.showConfirmDialog = (link) ->
  message = link.attr 'data-confirm'
  html = """
         <div class="modal" id="confirmationDialog">
           <div class="modal-header">
             <a class="close" data-dismiss="modal">×</a>
             <h3>#{message}</h3>
           </div>
           <div class="modal-body">
             <p>Are you sure you want to delete?</p>
           </div>
           <div class="modal-footer">
             <a data-dismiss="modal" class="btn">Cancel</a>
             <a data-dismiss="modal" class="btn btn-primary confirm">OK</a>
           </div>
         </div>
         """
  $(html).modal()
  $('#confirmationDialog .confirm').on 'click',-> $.rails.confirmed(link)

然后,您可以在视图中使用此类链接,它们应显示Bootstrap模式而不是标准浏览器弹出窗口：

<%= link_to 'Delete',item,:method => :delete,:confirm=>'Are you sure?' %>

UPDATE

这适用于我使用：remote =>真正的选择.

因此,如果我在index.html.erb视图中有类似以下内容：

<table>
  <tr>
    <th>Name</th>
    <th>Title</th>
    <th>Content</th>
    <th></th>
    <th></th>
    <th></th>
  </tr>

<% @posts.each do |post| %>
  <tr id="<%= post.id %>">
    <td><%= post.name %></td>
    <td><%= post.title %></td>
    <td><%= post.content %></td>
    <td><%= link_to 'Show',post %></td>
    <td><%= link_to 'Edit',edit_post_path(post) %></td>
    <td><%= link_to 'Destroy',post,method: :delete,:remote => true,data: { confirm: 'Are you sure?' } %></td>
  </tr>
<% end %>
</table>

并且控制器中的destroy动作在respond_to中有format.js：

# DELETE /posts/1
  # DELETE /posts/1.json
  def destroy
    @post = Post.find(params[:id])
    @post.destroy

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

这在destroy.js.erb中：

$("tr#<%= @post.id %>").fadeOut();

一切都行之有效.单击“销毁”链接时,将弹出“引导程序确认”对话框,单击“确定”后,该行将淡出并在服务器上销毁.
