如何在Backbone View中添加多个模型/集合？

var MyView = Backbone.View.extend({
  model: new Backbone.Model(),
  collection: new Backbone.Collection()
});

var MyView = Backbone.View.extend({
  model: new Backbone.Model(),
  collection: new Backbone.Collection(),

  initialize: function() {
    this.model.set('name', 'John');
    this.collection.add({ id: 1, name: 'Item 1' });
  }
});

var MyView = Backbone.View.extend({
  model: new Backbone.Model(),
  collection: new Backbone.Collection(),

  initialize: function() {
    this.model.set('name', 'John');
    this.collection.add({ id: 1, name: 'Item 1' });
  },

  render: function() {
    var html = '<h1>' + this.model.get('name') + '</h1>';
    this.collection.each(function(item) {
      html += '<p>' + item.get('name') + '</p>';
    });
    this.$el.html(html);
    return this;
  }
});
