ng-options loop through an array of objects within an object?

Question

I have this object format

{
      first_name : "Bob",
      last_name : "Smith",
      addresses : [
        {address:"1 Baker Street",
          city: "london"
        },
        {address:"2 Baker Street",
          city: "london"
        }
        ]
    }

I want to set the address bits in the select dropdown i.e. "1 Baker Street", "2 Baker Street",

This is my code

<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>

<div ng-app="myApp" ng-controller="myCtrl">

<select ng-model="selectedAddress" ng-options="item for item in testObject">
</select>

</div>

<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.testObject =     {
          first_name : "Bob",
          last_name : "Smith",
          addresses : [
            {address:"1 Baker Street",
              city: "london"
            },
            {address:"2 Baker Street",
              city: "london"
            }
            ]
        }
});
</script>

</body>
</html>

I'm struggling to get my head around how to loop through the objects with AngularJS. Any help?

your missing the testObject.addresses on html binding

You have to call the child object of array and the property. Take a look this code.

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.testObject =     {
          first_name : "Bob",
          last_name : "Smith",
          addresses : [
            {address:"1 Baker Street",
              city: "london"
            },
            {address:"2 Baker Street",
              city: "london"
            }
            ]
        }
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app="myApp" ng-controller="myCtrl">

<select ng-model="selectedAddress" ng-options="item.address for item in testObject.addresses">
</select>

</div>

Check this one:

 <select ng-model="selectedItem" 
         ng-options="selectedItem as selectedItem.address       
                     for selectedItem in testObject.addresses">  
</select>

You can also set default selectedItem as 1st item in list

$scope.selectedItem = $scope.testObject.addresses[0];
