srcmini本文概述
在Backbone.js中，排序收集方法用于对集合中的项目进行排序。它与比较器属性一起使用，以便对项目进行排序。
句法：
collection.sort(options)参数说明
options：它指定两个参数“ true”或“ false”以启用或禁用排序。
让我们以一个示例来部署排序收集方法。
请参阅以下示例：

<title>Sort Collection Example</title>

<body>
<script type="text/javascript">
var Player = Backbone.Model.extend(); //'Player' is a model name
//Players names will be displayed in ascending order.
var Players = [
{player: 'Ronaldo', id: '12'}, {player: 'Pele', id: '32'}, {player: 'Neymar', id:'18'}
];
//'myteam' is a collection instance and model 'Player' is specified using model property
var myteam = new Backbone.Collection(Players, {
model:Player, //The comparator method is used to maintain the collection in sorted order
comparator: 'player'
});
//display the sorted records, records are sorted based on player as we have set comparator to 'player'
document.write("The sorted items are: ", JSON.stringify(myteam.toJSON()));
</script>
</body>

将以上代码保存在sort.html文件中，然后在新的浏览器中打开该文件。
