Backbone 集合:sort【有bug，版本号：1.1.0】经典案例

例子1

varchapters = new Backbone.Collection;

chapters.comparator= 'page';

chapters.add(newBackbone.Model({page: 9, title: "The End"}), { sort: false});

chapters.add(newBackbone.Model({page: 5, title: "The Middle"}));

chapters.add(newBackbone.Model({page: 1, title: "The Beginning"}));

/*

注意：此处有bug，page:9不参加排序，而又第一个插入，所以排序

应为：page9，page1，page5，不应为page1，page5，page9

*/

alert(chapters.pluck('title'));// The Beginning,The Middle,The End

例子2

varchapters = new Backbone.Collection;
