EmberJS：拒绝即将到来的转型 [英] EmberJS: reject an upcoming transition

问题描述

我有一个emberjs应用程序，用于编辑对象的表单。

此页面包含一个保存按钮，将数据保存到数据库中。

I have an emberjs app, with a form to edit an object.
This page contains a "Save" button, which persists the data into the database.

如果对象很脏，并且用户将要转换到应用程序中的其他路径，我需要警告他们，如果拒绝该确认，则取消转换。

If the object is dirty and the user is going to be transitioned to an other path in the app, I need to warn them about that, and cancel the transition if they reject the confirmation.

App.ObjectEditRoute = Ember.Route.extend
  exit: ->
    if @get('model.isDirty')
      if confirm('All your changes will be lost')
        # We just keep rolling the chain of events and do the transition
      else
        # We want to cancel the transition

似乎没有任何

推荐答案

自从路由器改装以来，这很容易使用willTransition事件。

Since the router facelift, this is pretty easy to do using the willTransition event.

App.ObjectEditRoute = Ember.Route.extend
  events:
    willTransition ->
      if @get('model.isDirty')
        if confirm('All your changes will be lost')
          transition.perform()
        else
          transition.abort()
