Question

我有一个json

[ { "qpid": "41", "qbid": "4", "presentqb": "banktest", 
    "difficulty": [ 0, 0, 2, 0, 0 ], 
    "selQ": [ 0, 0, 0, 0, 0 ] }, 
  { "qpid": "41", "qbid": "6", "presentqb": "bank 29th", 
    "difficulty": [ 1, 1, 1, 0, 1 ], "selQ": [ 0, 0, 0, 0, 0 ] } ]

我希望根据json中的enteries数量使用下拉列表。下拉数量取决于selQ。下拉值中的值根据json中的难度而变化。当下拉值改变时，它应该进入json的selQ。我使用下面的代码

<div class="well" id="selectedQBs" style="height:200px" 
     ng-repeat="(k,selQB) in selQBs">
   <ul>
      <li>{{selQB.presentqb}}
          <a href ng-click="selQBs.splice($index, 1)">
              <span class="btn btn-mini btn-danger"><strong>x</strong></span>
          </a>
          <div>
             <div id="{{selQB.qbid}}" 
                  ng-repeat="sq in selQB.selQ track by $index" 
                  ng-hide="allocationtype == 4">

                 <select ng-model="selQBs[k].selQ[$index]" 
                         ng-options="n for n in range(selQB.difficulty[$index])">
                 </select>

             </div>
          </div>
      </li>
   </ul>
</div>

通过上面的代码，我无法将下拉列表的更改值与相应的div的selQ绑定

angular js使用ng-model动态绑定数据
