javascript - Why my angular code turns to comment? -

-

i use angularjs. html comment after render. why? before render code:

<select data-ng-model="selecteddate"> <option data-ng-repeat="date in oldrecords" value="{{}}">{{date}}</option> </select>

after render:

<section>      <select data-ng-model="selecteddate" class="ng-pristine ng-valid">         <!-- ngrepeat: date in oldrecords -->     </select>  </section>

its better use ng-options in case ,

there comment shown because $scope.oldrecords either doesn't exist or empty.
