表达：
它用于决定请求。很可能是字符串, 作品或集群。
反转：是自由裁量权。如果希望以相反的顺序显示数据, 请确保参数中的反向条件设置为true。
示例：通过名称进行排序

</ script >
< body >
< div ng-app = "myApp" ng-controller = "orderCtrl" >

< script >
var app = angular.module('myApp', []);
app.controller('orderCtrl', function($scope) {

});
</ script >
< p >The array items are arranged by "name".</ p >

示例：当我们通过"-"和" +" orderBy遍历gdp时, 按情况进行排序
