How can I populate a select dropdown list from a JSON feed with AngularJS?

63

I have been looking hard for examples but could not find anything at all. The only thing I know is that I could use the http module to get my data. Here is what I am currently doing, but it's coded with Knockout. Can someone give me some advice on how I could recode this feature using AngularJS?

HTML

<select id="testAccounts" 
   data-bind="options: testAccounts, optionsValue: 'Id', optionsText: 'Name', optionsCaption: 'Select Account', value: selectedTestAccount">
</select>

Javascript

<script type='text/javascript'>
    $(document).ready(function () {

        var townSelect = function () {
        var self = this;
        self.selectedTestAccount = ko.observable();
        self.testAccounts = ko.observableArray();
        var townViewModel = new townSelect();
        ko.applyBindings(townViewModel);

        $.ajax({
            url: '/Admin/GetTestAccounts',
            data: { applicationId: 3 },
            type: 'GET',
            success: function (data) {
                townViewModel.testAccounts(data);
            }
        });
    });
</script>

The proper way to do it is using the ng-options directive. The HTML would look like this.

<select ng-model="selectedTestAccount" 
        ng-options="item.Id as item.Name for item in testAccounts">
    <option value="">Select Account</option>
</select>

JavaScript:

angular.module('test', []).controller('DemoCtrl', function ($scope, $http) {
    $scope.selectedTestAccount = null;
    $scope.testAccounts = [];

    $http({
            method: 'GET',
            url: '/Admin/GetTestAccounts',
            data: { applicationId: 3 }
        }).success(function (result) {
        $scope.testAccounts = result;
    });
});

You'll also need to ensure angular is run on your html and that your module is loaded.

<html ng-app="test">
    <body ng-controller="DemoCtrl">
    ....
    </body>
</html>

<select name="selectedFacilityId" ng-model="selectedFacilityId">
         <option ng-repeat="facility in facilities" value="{{facility.id}}">{{facility.name}}</option>
     </select>  

This is an example on how to use it.
