使用对象作为过滤器：

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

进行“严格”比较，除非值与表达式完全相同，否则不会返回匹配项：

<div ng-app="myApp" ng-controller="arrCtrl">
<ul>
<li ng-repeat="x in customers | filter : 'London' : true">
    {{x.name + ", " + x.city}}
</li>
</ul>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('arrCtrl', function($scope) {
    $scope.customers = [
        {"name" : "London Food", "city" : "London"},
        {"name" : "London Catering", "city" : "London City"},
        {"name" : "London Travel", "city" : "Heathrow, London"}
    ];
});
</script>
