We take sample example for counties, we have list item show in the DOM pages. This item is have all counties, i want specific country is available from the list to check using angular filter concept. Filter is apply to search a specific country from the list.         This fetch ng-repeat filter concept using angular, this is fetch a corresponding scope of array object only. This happen DOM itself, no need to write logic from. HTML:    <div ng-app="searchApp"> <div ng-controller="searchCtrl">     Search : <input type="text" ng-model="search"/>     <ul ng-repeat="country in countries | filter:search">         <li>{{country.name}}</li>     </ul>     <p ng-show="(countries | filter:search).lengt...

An angularjs variable define is have a assign any value or not to find a default properties is angular.isUndefined. I will give a sample logic is undefined checking logic. HTML Code <div ng-app="testApp">     <div ng-controller="TestCtrl">         Variable $scope.name is undefined ==>> {{value1}}         <br/>        Variable $scope.place is undefined ==>> {{value2}}     </div> </div>   AngularJS  var app = angular.module('testApp',[]); app.controller('TestCtrl', function($scope){     $scope.name;     $scope.value1 = angular.isUndefined($scope.name);     $scope.place = "chennai";     $scope.value2 = angular.isUndefined($scope.place); }); Result: Demo

              Angular directive implements to custom filter concept is apply to filter large data array object will filter specific terms and condition write to yours. Angularjs have some basic filters directive is there. Some more filter need your project means, will try own filter concept is available from angularjs.            Custom filter is more reuse more project from this custom logic.
