ng-repeat中的Angular ng-options

I am unable add option elements to a select element using the ng-options directive. But am able to do this using the ng-repeat directive. Why?

我无法使用ng-options指令将选项元素添加到select元素。但是我可以使用ng-repeat指令来做到这一点。为什么？

<div ng-app ng-controller="DescAttrCtrl">

        </div>
        <select name="dattr-{{$index}}" ng-options="v for v in dattr.values">
                <option value=""> --- select a value --- </option>
         <!--   <option ng-repeat="v in dattr.values">{{v}}</option> -->
        </select>
    </div>
