定义和用法
orderBy 过滤器允许我们对数组进行排序。
默认情况下，字符串按字母顺序排序，数字按数值顺序排序。
语法
{{ array | orderBy : expression : reverse }}
参数值
| 值 | 描述 |
|---|---|
| expression | 用于确定顺序的表达式。表达式可以是以下类型： 字符串：如果数组是对象数组，您可以按某个对象属性的值对数组进行排序。请参阅下面的示例。 函数：您可以创建一个函数来组织排序。 数组：如果您需要多个对象属性来确定排序顺序，请使用数组。数组项可以是字符串和函数。 |
| reverse | 可选。如果想反转数组顺序，请将其设置为 true。 |

按“city”对数组进行排序
<div ng-app="myApp" ng-controller="orderCtrl">
<ul>
<li ng-repeat="x in customers | orderBy : 'city'">{{x.name + ", " + x.city}}</li>
</ul>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('orderCtrl', function($scope) {
$scope.customers = [
{"name" : "Bottom-Dollar Marketse" ,"city" : "Tsawassen"},
{"name" : "Alfreds Futterkiste", "city" : "Berlin"},
{"name" : "Bon app", "city" : "Marseille"},
{"name" : "Cactus Comidas para llevar", "city" : "Buenos Aires"},
{"name" : "Bolido Comidas preparadas", "city" : "Madrid"},
{"name" : "Around the Horn", "city" : "London"},
{"name" : "B's Beverages", "city" : "London"}
