設置在編輯之前將值選擇爲值

Question

我有一個表中填充了從使用AngularJS捕獲的服務中檢索到的對象的記錄。我在表格中有一個複選框，可以對該行進行編輯。在行內，我有一個選擇框，當我點擊行中的「編輯」複選框時，我仍然需要將其默認值設置爲行中的原始值，同時仍然使用所有其他值來填充選擇內容。

下面是填充表格和選擇框的代碼。

 <thead> 
      <tr> 
       <th class="col-lg-2">Sub Program</th> 
       <th class="col-lg-6">Description</th> 
       <th class="col-lg-2">Program</th> 
       <th class="col-lg-1">Edit</th> 
       <th class="col-lg-1">Update/Delete</th> 
      </tr> 
     </thead> 
     <tbody> 
      <tr ng-repeat="timeAllocationSubProgram in timeAllocationSubPrograms"> 
       <td ng-hide="checked">{{timeAllocationSubProgram.subProgramName}}</td> 
       <td ng-hide="checked">{{timeAllocationSubProgram.subProgramDescription}}</td> 
       <td ng-hide="checked">{{timeAllocationSubProgram.programName}}</td> 
       <td ng-show="checked"> 
        <input class="form-control" value="{{timeAllocationSubProgram.subProgramName}}" 
          ng-model="timeAllocationSubProgram.subProgramName" /> 
       </td> 
       <td ng-show="checked"> 
        <input class="form-control" value="{{timeAllocationSubProgram.subProgramDescription}}" 
          ng-model="timeAllocationSubProgram.subProgramDescription" /> 
       </td> 
       <td ng-show="checked"> 
        <select class="form-control" ng-options="timeAllocationProgram as timeAllocationProgram.programName 
          for timeAllocationProgram in timeAllocationPrograms track by timeAllocationProgram.programName" ng-model="timeAllocationProgram" 
          ng-change="selectProgram(timeAllocationProgram)"></select> 
       </td> 
       <td> 
        <input type="checkbox" ng-model="checked" aria-label="Toggle ngShow"/> 
       </td> 
       <td> 
        <button class="btn btn-xs btn-primary" ng-click="editTimeAllocationSubProgram(timeAllocationSubProgram)" 
          ng-show="checked"> 
         Update 
        </button> 
        <button class="btn btn-xs btn-primary" ng-click="deleteTimeAllocationSubProgram(timeAllocationSubProgram)" 
          ng-hide="checked"> 
         Delete 
        </button> 
       </td> 
      </tr> 
     </tbody> 
    </table>

隨着我卑微的經驗，爲默認值設置爲鏈接到NG-模型角度投入的最好辦法，就是設定的默認值了NG-模型。

NG選項這裏remplacing

<options ng-repeat="timeAllocationProgram in timeAllocationPrograms"> 

因此，如果timeAllocation（因爲它寫的是什麼在NG-模型指令）設置爲你想要的時候，你從服務加載數據的默認值，它應該顯示它的權利。
