AngularJS – isObject() method

The isObject() method in AngularJS basically checks if a reference is an Object or not. This method will return True if the reference passed inside the function is an Object, else it will return False.

Note − NULL values are not considered as an Object, but JavaScript arrays are objects.

Syntax

angular.isObject(value)

Example − Check if the reference is an Object or not

Create a file "isObject.html" in your Angular project directory and copy-paste the following code snippet.

<!DOCTYPE html>
<html>
   <head>
      <title>angular.isObject()</title>

      <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.2/angular.min.js">
      </script>
   </head>

   <body ng-app="app" style="text-align:center">
      <h1 style="color:green">
         Welcome to Tutorials Point
      </h1>
      <h2>AngularJS | angular.isObject()</h2>

      <div ng-controller="example">
      <b>Value: {{value}}</b>
      <br><br>
      {{isObject}}
      <br><br>
      <b>Value: null</b>

   </div>

   <!-- Script for passing the values and checking... -->
   <script>
      var app = angular.module("app", []);
      app.controller('example',['$scope', function ($scope)
      {

         $scope.value = {name: "Tutorials Point"};
         $scope.value2 = null;
         $scope.value3 = [{id:'1'},{id:'2'},{id:'3'},{id:'4'},{id:'5'}];
         $scope.value4 = "Tutorials Point";

         $scope.isObject = angular.isObject($scope.value) == true
            ? "$scope.object is an object."
            : "$scope.object is not an object.";

         $scope.isObject1 = angular.isObject($scope.value2) == true

         $scope.isObject2 = angular.isObject($scope.value3) == true

         $scope.isObject3 = angular.isObject($scope.value4) == true
