如何在Backbone

Question

如何在Backbone中添加多个模型到集合

    formatChannelIds: function() {

    _this = this;

    // var activeIds ='';


    _.filter(_this.modelChannelList.toJSON(), function(channelObj) {
      if (channelObj['isactive'] == true) {
        //   activeIds =activeIds+','+channelObj['id'];
        console.log(channelObj['id']);
        _this.modelChannelStats.fetch({
          data: {
            channel: channelObj['id']
          },
          processData: true
        }, {
          success: function(model, response, options) {



            _this.channelstatsCollection.push(model);



          }

        });

      }

    });

    console.log(_this.channelstatsCollection);
    console.log(_this.modelChannelStats);


  }

我的集合在数组中显示为null。

Fetch方法接受一个包含所有必要参数的对象。

_this.modelChannelStats.fetch({
         data: {
           channel: channelObj['id']
         },
         processData: true,
         success: function(model, response, options) {
           _this.channelstatsCollection.push(model);

        }

    });

尝试使用这段代码。
