Backbone 集合add使用案例

Backbone 集合add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();

books.on("add",function(book) {

alert("添加"+ book.get("title") + "!");

});

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

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

注意add方法还带有可选参数，{at:index, merge:true/false }具体用法参看push方法。
