Ember.js:从嵌套路由调用ApplicationRoute的操作

Question

假设我有一个ApplicationRoute动作goBack(正如你在评论中看到的那样,由于不同移动浏览器中的错误,我需要自己处理goBack):

Mobile.ApplicationRoute = Em.Route.extend
    actions:
        goBack: ->
            # TODO: Remove when iOS 7 fixed their history
            # If there's no route to go back, go to front
            # TODO: Remove when Microsoft fixed their
            # back button in offline mode
            if not (Nn.MobileHelper.isiPhone() or Nn.MobileHelper.isIeMobile()) and @get("router.recentRoute")?
                return window.history.back()

            @get("controller").set("isHitBackButton", true)

            @transitionTo("front").then => @get("controller").set("isHitBackButton", false)

如何从其他路线触发此操作？请注意,因为我需要调用@transitionTo,所以这段代码必须在路由中.

默认情况下,操作会冒泡到应用程序路径!只需{{action 'goBack'}}在您的模板中使用,或从代码(减去组件)调用this.send('goBack').从组件中您需要连接事件调用稍微不同并使用this.sendAction('internalActionName').
