Angularjs 动态ng模型值不适用于双向数据绑定

我是个新手

我使用动态字段创建了表单。在这里我需要创建动态ng模型值，比如字段[lable.LabelID]，这里lable.LabelID是动态值

这是我的模板页面

 <form ng-submit="" ng-controller="saveOrder">
  <table class="col-xs-12 col-sm-8 col-sm-offset-4">
     <tr ng-repeat="lable in Grp.Label">
       <td style="width:30%" class="no-wrap text-left col-xs-text-center text-primary">
        <h4>{{lable.LabelName}}</h4>
       </td>
       <td style="width:60%" class="no-wrap  text-left">
           <input type="{{input_type[lable.InputType]}}" 
           name="{{lable.LabelID}}" ng-model="Field[lable.LabelID]" 
            ng-init="Field[lable.LabelID] = Field[lable.LabelID] || {}"/>
       </td>
    </tr>
 </table>

我的服务器数据如下

{
   "GroupName": "Order Form",
   "Label": [
     {
        "InputType": "1",
        "LabelID": "1",
        "LabelName": "BillingDetails"
     },
     {
        "InputType": "1",
        "LabelID": "2",
        "LabelName": "shipping Details"
     }
    ]
 }

对于这种情况，我得到的错误如下

  TypeError: Cannot set property '1' of undefined

我发现这类问题很多。但我无法为我的场景找到解决方案。请帮我解决这个问题

任何类型的帮助都是可观的。

尝试设置

$scope.Field=[]在控制器内，并删除
ng init
指令。在您当前的代码中，当编译发生时，
$scope.Field
是未定义的。
您在哪里设置Grp.Label？我从服务器调用中获取所有这些数据，格式如下{“GroupName”：“Order Form”，“Label”：[{“InputType”：“1”，“LabelID”：“1”，“LabelName”：“BillingDetails”}，{“InputType”：“1”，“LabelID”：“2”，“LabelName”：“shipping Details”}]}您是否尝试设置
$scope.Field=[]；
在控制器中并删除ng init指令？@CorySilva是的。我尝试了，但出现了相同的错误..TypeError:无法设置的属性“1”undefined@CorySilva我试过使用$scope.Field=[]；现在工作正常..谢谢兄弟。。。。
