Two examples of binding JSON-annotated object with select in HTML using AngularJS

angular_select

$scope.sort = 'relevance';

$scope.sorting = {
  'relevance': 'Relevant',
  'date-posted-desc': 'Recent',
  'interestingness-desc': 'Interesting'
};

$scope.sorting2 = [
  {'id': 'relevance', 'text': 'Relevant'},
  { 'id': 'date-posted-desc', 'text': 'Recent'},
  { 'id': 'interestingness-desc', 'text': 'Interesting'}
];

<!-- No options is rendered if ng-models is missing. -->
<select ng-model="sort" ng-options="k as v for (k,v) in sorting"></select>
<select ng-model="sort" ng-options="sort.id as sort.text for sort in sorting2"></select>
