Backbone:如何从模型中引用Collection

const Backbone = require('backbone');
const MyModel = require('../models/MyModel');

const MyCollection = Backbone.Collection.extend({
  model: MyModel
});

module.exports = MyCollection;

const MyCollection = require('../collections/MyCollection');

const myCollection = new MyCollection();

// 添加模型到Collection中
const myModel = new MyModel({ name: 'John Doe' });
myCollection.add(myModel);

// 从Collection中获取模型
const firstModel = myCollection.at(0);
console.log(firstModel.get('name')); // 输出 "John Doe"
