Definisie en gebruik
Die filterfilter laat ons toe om 'n skikking te filtreer, en 'n skikking terug te gee wat slegs die ooreenstemmende items bevat.
Hierdie filter kan slegs vir skikkings gebruik word.

items from the array. The expression can be of type: String: The array items that match the string will be returned. Object: The object is a pattern to search for in the array. Example:

{{x.name + ", " + x.city}}

Voorbeeld
Doen 'n "streng" vergelyking, wat nie 'n passing gee nie, tensy die waarde presies dieselfde is as die uitdrukking:
<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"}
];
});
