Backbone.js 如何让触发器正确监听

我很难让我的触发器做出正确的反应。我有很多工作，但其中一个没有，我不明白为什么

这是我的AppController类

class ProjectOrder.View.AppController extends Backbone.View
  initialize: ->
    @promptOfficeSearch()

  promptOfficeSearch: ->
    officeSearch = new ProjectOrder.View.OfficeSearch
    officeSearch.on 'createOffice', @promptOfficeCreate
    officeSearch.on 'createTicket', @promptTicketCreate
    officeSearch.on 'accountAndTicketExist', @killProcessAccountExists


 promptOfficeCreate: (serial) ->
   @officeModel = new ProjectOrder.Model.OfficeModel()
   @officeModel.set('serial_number', serial)

   officeCreate = new ProjectOrder.View.OfficeCreator({model: @officeModel})
   officeCreate.on 'createTicketOffAccount', @promptTicketCreate

 promptTicketCreate: (model) ->
   console.log 'promptTicketCreate'
   model = model || @officeModel
   ticketModel = new ProjectOrder.Model.TicketModel()
   new ProjectOrder.View.TicketCreator({ticketModel: ticketModel, officeModel: model})

 killProcessAccountExists: (ticket_id) ->
   msg = document.createElement 'div'
   msg.className = 'account-exists-msg'
   msg.innerHTML = "Account already exists. Redirecting to ticket #{ticket_id}..."

   $('#create-order-div').append(msg)
   setTimeout((->
     window.location = "/pto/#{ticket_id}"
   ), 2000)

promptOfficeSearch函数中officeSearch对象的所有触发器都工作正常。它们分别按如下方式触发：

@trigger 'createOffice', serial
@trigger 'createTicket', data.model[0]
@trigger 'accountAndTicketExist', data.model

但是，对于promptOfficeCreate中的officeCreate对象，它不会响应CreateTicketOffFaccount事件，该事件在my OfficeCreator类的submitOffice ajax成功回调中注册：

class ProjectOrder.View.OfficeCreator extends Backbone.View
  template: _.template($("#OfficeCreator").html())
  id: 'office-creator'
  events:
    'click .submit'     : 'submitOffice'

  initialize: ->
    @render()

  render: ->
    @$el.html(@template(@model.toJSON()))
    $('#create-order-div').append(@$el)

  submitOffice: ->
    @setModelData()
    @model.save(null,{
      success: (model) =>
        @trigger 'createTicketOffAccount', model
        #@$el.remove()
      error: ->
        alert 'error'
    })

  setModelData: ->
    @model.set({
      office_name:    $('#office').val()
      doctor_name:    $('#doctor').val()
      emr:            $('#has-emr').is(':checked')
      forms_builder:  $('#has-forms').is(':checked')
      iehr:           $('#has-iehr').is(':checked')
      clipboard:      $('#has-clip').is(':checked')
      specialty_id:  $('#specialty').val()
    })

你知道我的触发器为什么不工作吗？

我想你需要在你的

AppController

类中的所有方法上加上粗箭头

此事件激发时：

officeSearch.on 'createOffice', @promptOfficeCreate

promptOfficeCreate

函数作为普通函数调用，而不是作为

this

绑定到控制器实例的方法调用，因此发生这种情况时：

officeCreate.on 'createTicketOffAccount', @promptTicketCreate

---

@prompticketcreate

未定义，事件绑定未正确连接。

我没有将事件处理程序绑定到模型实例。它绑定到了officeCreate的一个实例（它是一个主干视图）

officeCreate

。是的，你完全正确。该方法在错误的对象上被调用，失去了AppController上此的焦点。谢谢你的帮助！
