javascript-仅重新渲染Marionette.js CollectionView的更改部分

下面是我当前拥有的代码,这些代码在每次添加或删除模型时都会重新呈现collectionView.但是,这似乎效率低下,因为每次我真正需要的只是删除一个modelView或添加一个modelView时,都必须渲染整个事物.那么我该如何实现呢？

var CollectionView = Marionette.CollectionView.extend({

    childView: ModelView,

    initialize: function() {
        [ "add", "remove" ].forEach(function(eventName) {
            this.listenTo(this.collection, eventName, this.render, this);
        }.bind(this));
    }

});

在此先感谢您提供的任何帮助！

解决方法:

这已经完成了automatically in Marionette：

When a model is added to the collection, the collection view will
render that one model in to the collection of item views.

When a model is removed from a collection (or destroyed / deleted),
the collection view will close and remove that model’s item view.
