I have a data array which contains many objects (JSON format). The following can be assumed as the contents of this array:

var data = [
  {
    "name": "Jim",
    "age" : 25
  },
  {
    "name": "Jerry",
    "age": 27
  }
];

Now, I display these details as:

 ng-repeat="person in data | filter: query">

Here, query is modeled to an input field in which the user can restrict the data displayed.

Now, I have another location in which I display the current count of people / person being display, i.e Showing {{data.length}} Persons

What I want to do is that when the user searches for a person and the data displayed is filtered based on the query, the Showing...persons also change the value of people being shown currently. But it is not happening. It always displays the total persons in data rather than the filtered one - how do I get the count of filtered data?

<body ng-controller="MainCtrl">
     ng-model="search" type="text">
    
Showing {{data.length}} Persons;
Filtered {{counted}}
    ng-repeat="person in data | filter:search"> {{person.name}}
body> <script> var app = angular.module('angularjs-starter', []) app.controller('MainCtrl', function($scope, $filter) { $scope.data = [ { "name": "Jim", "age" : 21 }, { "name": "Jerry", "age": 26 }, { "name": "Alex", "age" : 25 }, { "name": "Max", "age": 22 } ]; $scope.counted = $scope.data.length; $scope.$watch("search", function(query){ $scope.counted = $filter("filter")($scope.data, query).length; }); });
