要设置空值，这是控制器-

function display($scope) {
   $scope.obj ={"selected":null};
   $scope.objects = [{id: 1, value: "Yes"}, {id: 0, value: "No"}]
}

以下是模板-

<div ng-controller = "display">
   <select ng-model = "obj.selected"
      ng-options = "value.id as value.value for value in objects">
      <option value = "">Unknown</option>
   </select>
<br/>
   {{obj}}
</div>
