按 "city" 对数组进行降序排序：

<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"},
