我正在使用Backbone-nested插件，将我的声明Models为Backbone.NestedModel.extend()：https ://github.com/afeld/backbone-nested
这使我可以这样检索数据：this.model.get('tasks.title')
我遇到的问题是渲染每个嵌套项目。我可以使用 1 输出this.model.get('tasks[0].title')。
但是，如果我编写一个循环来迭代每个嵌套的，当在方法return this;之后调用时，将 追加回，它会失败。render()$elCollection $el
问题
如何编写一种有效的方法将嵌套元素呈现到集合视图？
集合视图
App.Views.Tasks = Backbone.View.extend({
el: '#taskList',
initialize: function() {
Event.on('tasks:show', this.show, this);
this.collection.on('add', this.addOne, this);
},
render: function() {
this.collection.each(this.addOne, this);
return this;
},
addOne: function(project) {
console.log(project.toJSON());
var taskView = new App.Views.Task({ model: project });
this.$el.append(taskView.render().el);
},
show: function(id) {
var project = this.collection.get(id);
var taskView = new App.Views.Task({ model: project });
this.$el.html(taskView.render().el);
}
});
