AngularJs ng-repeat with index

Question

我只想在单击显示按钮时在此部分中显示名称。我正在尝试使用索引进行检测，但没有成功。
Code :

<div ng-repeat="c in customers">

   <a ng-click="display(c.id[$index])" ng-hide="need to hide after click this one">{{vm.updateText}}</a>
   <div ng-show="c.id[$index]" class="updateSection">
        <input type="text" name="id" data-ng-model="id" />
          <input type="button" ng-click="vm.veryId(id)" value="{{vm.verifyButtonText}}">
          <input type="button" ng-click="vm.Cancel()" value="{{vm.cancelButtonText}}">
       </div>
    </div>
    // will show ng-click="vm.veryId(id)"
    <rpe-progress data-ng-show="vm.showProgress" block="true"></rpe-progress>
    // if id is working will show following error message:
    <rpe-alert show="vm.mpnIdAlert">{{vm.errormessage}}</rpe-alert>        



<script>
   vm.display= function (index) {    
      vm.id[index] = true;  
  //   I want show updatesection & hide Update text   
   }
vm.cancel= function () {   
//   I want hide updatesection & show Update text 
       }


  vm.veryId= function (id) {   
    //  If id is wrong show error message.
           }
</script>

如果我正确理解你的问题，你应该使用 track by

举个例子:

<div ng-repeat="n in [42, 42, 43, 43] track by $index">
  {{n}}
  <p ng-show="$index === 3">Index is 3</p>
</div>
