获取骨干示范实例的模型/类名 [英] Get a Backbone Model instance's model/class name

问题描述

由于主干模型的实例，我怎么能知道阶级这个实例的（这么说）？

例如：

 类汽车扩展Backbone.Modelmycar =新车（）
 

和我需要的是：

  mycar.modelName＃=＆GT; '汽车'
 

解决方案

这是一般的问题，我想。我要建议一些在这里提到的选项（<一个href=\"http://stackoverflow.com/questions/332422/how-do-i-get-the-name-of-an-objects-type-in-javascript\">How我是否能够得到在JavaScript中对象的类型的名称？），但我是有第一个选项的问题。你总是可以延长你所有的车型有返回的名称为模型的功能，但我能理解为什么您可能会发现不尽如人意。

Given an instance of Backbone model, how can I know the "class" (so to speak) of this instance ?

For instance:

class Car extends Backbone.Model

mycar = new Car()

And what I need is:

mycar.modelName # => 'Car'

解决方案

It's problematic in general, I think. I was going to suggest some of the options mentioned here ( How do I get the name of an object's type in JavaScript? ) but I was having issues with the first option. You could always extend all your models to have a function that returned a "name" for the model, but I can understand why you might find that less than satisfactory.
