How to iterate over the keys and values with ng-repeat in AngularJS ?

Last Updated : 12 Jul, 2025

The task is to iterate over a JS object (its keys and values) using the ng-repeat directive. This can be done using parenthesis in the ng-repeat directive to explicitly ask for a key-value pair parameter from angularJS. Here the variable key contains the key of the object and value contains the value of the object.

Syntax:

<element ng-repeat="(key, value) in JSObject">
     Contents... 
</element>

Example 1: In this example, we will simply display all the keys and values of a JS object using ng-repeat. In first iteration, key = name and value = "GeeksforGeeks". In the 2nd iteration, key = location and value = "Noida India Sector 136"...This keeps on iterating until all the keys and their values are covered at least once similar to a for-each loop.

HTML

<!DOCTYPE html>
<html ng-app="myApp">

<head>
    <script src=
"https://ajax.googleapis.com/ajax/libs/angularjs/1.7.8/angular.min.js">
    </script>
</head>

<body ng-controller="MyController">
    <center>
        <h1 style="color: green;">
            GeeksforGeeks
        </h1>
        <h3>
           Iterating the keys & values with ng-repeat in AngularJS 
        </h3>
        <div ng-repeat="(key, value) in gfg">\
        
            <!-- First Iteration-->
            <p>{{key}} - {{value}}</p>
        </div>
    </center>
    <script type="text/javascript">
        var myApp = angular.module('myApp', []);
        myApp.controller('MyController', ['$scope', function($scope) {
            $scope.gfg = {
                Name: "GeeksforGeeks",
                Location: "Noida India Sector 136",
                Type: "Edu-Tech",
            }
        }]);
    </script>
</body>
</html>

Output: On loading the page, we see that all the key-value pairs of the objects are already listed there. This is because the ng-repeat is called on load as the HTML gets loaded.

Example 2: In this example, we will loop over a nested object using the ng-repeat directive. In the first iteration, key = diamond and value = {hardness:"Ultra Hard", goodFor:"Display, cutting"} in the next iteration key = gold and value is its respective object. This keeps on iterating like a for-each loop over the key-value pairs of the object materials.

            <div ng-repeat="(key1, value1) in value">
                
                <!-- since the "value" variable itself is
                an object. We can iterate over its keys
                and values again using ng-repeat. -->
