angularjsHow do I use the AngularJS filter pipe?

The AngularJS filter pipe is used to filter an array of data to return a subset of the data that meets certain criteria.


<div ng-app="myApp" ng-controller="MyController">
    <li ng-repeat="person in people | filter:myFilter">
      {{ person.name }}

  var app = angular.module('myApp', []);

  app.controller('MyController', function($scope) {
    $scope.people = [
      {name: 'John', age: 25},
      {name: 'Jane', age: 30},
      {name: 'Jim', age: 27}
    $scope.myFilter = function(person) {
      return person.age > 25;

Output example

  • Jane
  • Jim

The code above uses the AngularJS filter pipe to filter the array of people and return only the people with an age greater than 25.

The code consists of the following parts:

  1. A <div> element with an ng-app and ng-controller attribute to define the application and controller.
  2. An <ul> element with an ng-repeat attribute to loop through each item in the people array.
  3. A filter:myFilter expression in the ng-repeat attribute to use the myFilter function to filter the people array.
  4. A $scope.people array of objects with each object containing a name and age property.
  5. A $scope.myFilter function to filter the people array and return only the people with an age greater than 25.

For more information on the AngularJS filter pipe, see the AngularJS documentation.
