我的引导模式不会触发控制器中的销毁操作

Question

我想将销毁操作中的默认浏览器确认更改为引导模式窗口。我找到了this implementation，我需要对其进行更改以符合 Bootstrap 3 模态 HTML。不幸的是，当我单击“删除”时，什么也没有发生。我尝试将remote: true 放在视图中的销毁操作链接中，并在控制器的销毁操作中响应format.js。

我还查看了here 和here，但找不到将解决方案应用于我的代码的方法。

这是我的代码：

视图中的链接：

<%= link_to '', task, method: :delete, 
                          data: { confirm: 'Do you want to delete this task?' }, 
                          class: "destroy-btn glyphicon glyphicon-trash" %>

tasks.js.coffee：

# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://coffeescript.org/
jQuery ->
    $('.best_in_place').best_in_place()

    $.rails.allowAction = (link) ->
      return true unless link.attr('data-confirm')
      $.rails.showConfirmDialog(link)
      false #if I remove this line, destroy works, but automatically, without pressing the button

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

    $.rails.showConfirmDialog = (link) ->
      message = link.attr 'data-confirm'
      html = """
                <div class="modal fade" id="confirmationDialog">
                          <div class="modal-dialog">
                            <div class="modal-content">
                              <div class="modal-header">
                                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                                <h4 class="modal-title">Delete task?</h4>
                              </div>
                              <div class="modal-body">
                                <p>#{message}</p>
                              </div>
                              <div class="modal-footer">
                                <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
                                <button type="button" class="btn btn-danger confirm">Delete</button>
                              </div>
                            </div>
                          </div>
                        </div>
             """
      $(html).modal()
      $('#confirmationDialog .confirm').on 'click', -> $.rails.confirmed(link)

控制器：

  def destroy
    @task.destroy
    respond_to do |format|
      format.html { redirect_to tasks_url }
      format.json { head :no_content }
    end
  end

application.js：

// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,

关于如何使销毁操作真正与引导模式一起工作的任何提示？

Answer 1

首先检查你的点击事件是否被捕获，如果没有，那是因为选择器。

这是我的情况，我可以通过将 $('#confirmationDialog .confirm').on 'click' 更改为来解决它 $(html).find('.confirm).on 'click'
