Backbone.js 主干.木偶项目视图事件冒泡问题

我有一个团队列表，团队中有一个任务列表。JSON数据如下所示：

{
    {"teamId":38,
     "teamName":"Analytics",
     "tasks":{
        {
            "taskId":93561,
            "taskName":"Analytics Country Report"
        }
      }
    },
    {"teamId":32,
     "teamName":"Client Service - Team Beaumont",
     "tasks":{
        {
            "taskId":93558,
            "taskName":"Project Management"
        }
      }
    },
    {"teamId":34,
     "teamName":"Copy",
      "tasks":{
        {
            "taskId":93580,
            "taskName":"Copy"
        }
      }
    },
    {"teamId":48,
     "teamName":"Engineering  - Team LZ",
     "tasks":{
        {
            "taskId":93573,
            "Front-end Development"
        },
        {
            "taskId":93562,
            "taskName":"Quality Control"
        }
      }
    }
}

View.SchedulingTask = Backbone.Marionette.ItemView.extend({
    template: 'resource-planning/scheduling/templates/_scheduling-task',
    className: 'scheduling-task-handle',

    initialize: function() {
        var _this = this;
        App.vent.on( "scheduling:task:remove:" + _this.model.get('taskId'), function(){
            console.log('Task removed' + _this.model.get('taskId');
            _this.trigger('task:remove');
            _this.remove();
        })
    },
});

View.SchedulingTeam = Backbone.Marionette.CompositeView.extend({
    template: 'resource-planning/scheduling/templates/_scheduling-team',
    itemView: View.SchedulingTask,

    initialize: function(){
        this.collection = _this.model.get('tasks');
        this.on('itemview:task:remove', function(itemView){
            console.log("Team: task removed: " + _this.model.get('teamId'));
    // If the collection is empty, I need to remove the team as well
        });
    }
});

我的观点：

{
    {"teamId":38,
     "teamName":"Analytics",
     "tasks":{
        {
            "taskId":93561,
            "taskName":"Analytics Country Report"
        }
      }
    },
    {"teamId":32,
     "teamName":"Client Service - Team Beaumont",
     "tasks":{
        {
            "taskId":93558,
            "taskName":"Project Management"
        }
      }
    },
    {"teamId":34,
     "teamName":"Copy",
      "tasks":{
        {
            "taskId":93580,
            "taskName":"Copy"
        }
      }
    },
    {"teamId":48,
     "teamName":"Engineering  - Team LZ",
     "tasks":{
        {
            "taskId":93573,
            "Front-end Development"
        },
        {
            "taskId":93562,
            "taskName":"Quality Control"
        }
      }
    }
}

View.SchedulingTask = Backbone.Marionette.ItemView.extend({
    template: 'resource-planning/scheduling/templates/_scheduling-task',
    className: 'scheduling-task-handle',

    initialize: function() {
        var _this = this;
        App.vent.on( "scheduling:task:remove:" + _this.model.get('taskId'), function(){
            console.log('Task removed' + _this.model.get('taskId');
            _this.trigger('task:remove');
            _this.remove();
        })
    },
});

View.SchedulingTeam = Backbone.Marionette.CompositeView.extend({
    template: 'resource-planning/scheduling/templates/_scheduling-team',
    itemView: View.SchedulingTask,

    initialize: function(){
        this.collection = _this.model.get('tasks');
        this.on('itemview:task:remove', function(itemView){
            console.log("Team: task removed: " + _this.model.get('teamId'));
    // If the collection is empty, I need to remove the team as well
        });
    }
});

在另一个视图的某个地方，我触发了以下事件：我希望删除任务93558。 App.vent.trigger（“调度：任务：删除：93558”）

我希望看到的是：

'任务已删除93558'

“团队：任务已删除：32”

但我们看到的是：

'任务已删除93558'

“团队：任务已删除：48”

似乎itemView事件冒泡未冒泡到正确的CollectionView

请有人帮我解释一下。

如果你这样做会发生什么而不是

var\u this=this？是的，我知道你可能不再研究这个了，但我想知道这与
这个
是如何绑定的。或者，您可能需要在
View.SchedulingTeam.initialize
的主体中添加一条或另一条语句。
