javascript - Ember.js 从控制器获取数据

Question

我有一个控制器，我在其中定义TakenSeatNumbers变量：

TravelClient.TourSeatsController = Ember.ObjectController.extend({
  selectSeat: function(seat) {
    var orderTransaction = TravelClient.store.transaction();
    var takenSeatNumber = orderTransaction.createRecord(TravelClient.TakenSeatNumber, {number: seat.get('id')});
  }
});

如何TakenSeatsNumbers从tour/seats模板访问？该模型Tour在TourSeatsController.

根据我的评论，将该函数变量 ( takenSeatsNumber) 提升为控制器内的一个属性，以便它是公共的，类似于以下内容：

TravelClient.TourSeatsController = Ember.ObjectController.extend({
  takenSeatNumber: null, 
  selectSeat: function(seat) {
    var orderTransaction = TravelClient.store.transaction();
    this.set('takenSeatNumber', 
             orderTransaction.createRecord(TravelClient.TakenSeatNumber, {number: seat.get('id')})
    );
  }
});
