一步销毁集合中的主干模型? [英] Destroying a Backbone Model in a Collection in one step?

问题描述

删除模型是否必须执行这两个步骤?

Are these two steps mandatory to delete a Model?

var model = collection.get(id);
model.destroy();
collection.remove(model);

当模型从集合中移除时，没有办法销毁模型吗?

Isn't there a way to destroy a model when it is removed from its collection?

推荐答案

Model.bind("remove", function() {
  this.destroy();
});
...
var model = new Model();
...
collection.remove(model);

从集合中移除模型会触发 "remove" 事件.

Removing a model from a collection triggers the "remove" event.

因此，如果您愿意，可以让模型绑定到它们并销毁它们自己.

So if you want to, you can get models to bind to them and destroy themselves.
