`In AngularJS, the default selection option is not functioning as expected`

I'm struggling with a particular issue in my code.

<select ng-model="selected_student" class="form-control">
    <option ng-repeat="obj in students" value="{{obj.id}}">{{obj.name}}</option>
</select>

When I try to set the selected_student in the controller like this:

$scope.selected_student = $scope.students[0];

it doesn't seem to be working as expected.

If you would like to take a look at my code, here's the link to my fiddle

Answer №1

Consider using the ng-options directive:

<select ng-model="selected_book" class="form-control" ng-options="book.id as book.title for book in library">

In your controller:

$scope.selected_book = $scope.library[0].id;

Check out this working example on jsfiddle:

This solution should meet your needs.
