Backbone 集合:reset使用案例

Backbone 集合:reset使用案例

例子1

varBook = Backbone.Model.extend({

defaults : {

title :'unknown',

author :'unknown'

}

,publish:function(){

alert(this.get("title"));

}

});

varjava = new Book({ title:"java", author:"java author"})

,ruby= new Book({ title:"ruby", author:"ruby author"})

,jsp= new Book({ title:"jsp", author:"jsp author"});

varbooks = new Backbone.Collection();

//三个弹出框，输出："添加java!","添加ruby!","添加jsp!"

books.add([java, ruby, jsp ]);

books.remove([java,ruby]); // books.length == 1 且books.at(0)指向jsp

//此时重置集合，books包含java、ruby两个book对象

books.reset([java,ruby]);

//此时重置集合，books包含0个book对象，books.length== 0

books.reset();
