茅曾琪
Model集合，Collection，用法类似java中的ArrayList。

//1、为dom注册事件，设备加载完成后回调createObject()方法
$(document).ready(function(){
document.addEventListener("deviceready", createObject, false);
});
//2、定义一个模型
var TodoItem=Backbone.Model.extend({
initialize: function(){
}
});
//3、定义一个Collection，是一个Model的集合，可以理解为java中的ArrayList
var TodoList=Backbone.Collection.extend({
//Collection中允许的Model类
model:TodoItem
});
var todoList=new TodoList();
//4、创建2个TodoItem类的对象，放入到Collection中
function createObject(){
var todoItem1=new TodoItem({
item:"todoItemTest1"
});
var todoItem2=new TodoItem({
item:"todoItemTest2"
});
todoList.add(todoItem1);
todoList.add(todoItem2);
}
//5、点击按钮，获取Collection的长度
function onClickFuc(){
alert(todoList.length);
}
