我有下表：Lot Table View
我使用三个ng-repeat来显示以下响应。 Response from backend overview
Detailed response from backend
第一次ng重复是在<tbody>。第二次ng重复是在<tr>。第三个是重复批次详情，Trx数量和余额，这是<span>。
以下是我的HTML代码：
<table id="lotTable" class="table table-striped table-bordered table-vmiddle">
<thead>
<tr>
<th>S No.</th>
<th>Lot No.</th>
<th>Lot Qty</th>
<th>Unit Cost</th>
<th>Lot Details</th>
<th>Trx Qty</th>
<th>Balance</th>
</tr>
</thead>
<tbody ng-if="isDataLot=='yes'" ng-repeat-start="l in lotData track by $index"
ng-init="parentIndex = $index" id=parentRow{{$index}}
data-id="{{l.lotNo}}">{{$index}}
<tr ng-repeat="k in l track by $index">
<td class="indextrack" >{{$index+1}}
</td>
<td class="lotNo">
<input type="hidden" class="hiddenLotNo" value="{{l.lotNo}}"/>
{{ k.lotNo }} <br>
{{k.grnNo}} ({{k.grnDate}}) <br>
{{k.inPermit}} {{k.physicalLocationName}}
</td>
<td class="lotQty">{{k.lotQty}}
</td>
<td class="cost">{{ k.unitPrice | number:4}}
</td>
<!-- Lot Details -->
<td class="lotDetails" style=" line-height: 28px; ">
<span ng-repeat="c in k.lotDetails">
<input type="hidden" class="hiddenLotDetails m-b-5"
id="lotDetails{{$parent.$parent.$index}}{{$parent.$index}}{{$index}}"
ng-model="xxx[$index]" value="{{c}}"/>
{{c | ctnchange : c}}<br>
{{$parent.$parent.$index}}{{$parent.$index}}{{$index}}
</span>
</td>
<!-- Transaction Quantity -->
<td class="trxQty" style="padding-top: 10px; padding-bottom: 10px;">
<span ng-repeat="c in k.lotDetails track by $index" >
<input class="trxQuantity m-b-5 text-right"
id="trx{{$parent.$parent.$index}}{{$parent.$index}}{{$index}}"
autocomplete="off"
ng-model="trx[$parent.$index][$index]"
ng-keyup="calculateBal($parent.$index,$index); checkParentCheckbox($event);addTrxQty();"
style="width: 60px;" integers-only/><br>
</span>
</td>
<!-- Balance -->
<td class="balanceNew" style="padding-top: 10px; padding-bottom: 10px;">
<span ng-repeat="c in k.lotDetails track by $index">
<input ng-disabled="true" class="balanceNew m-b-5 text-right"
id="balNew{{$parent.$parent.$index}}{{$parent.$index}}{{$index}}"
type="text" style="width: 60px;"/>
<br>
</span>
</td>
</tr>
</tr>
</tbody>
<tbody ng-repeat-end></tbody>
我想动态命名Lot Details，Trx Qty和Balance的模型。我使用id="trx{{$parent.$parent.$index}}{{$parent.$index}}{{$index}}为交易数量命名了ID。我想为ng-model实现同样的目标。
我用过ng-model="trx[$parent.$index][$index]。但我有三个嵌套的ng-repeat。这适用于两个嵌套的ng-repeat。怎样才能进行三次重复？另外，我必须在控制器中设置$scope.trx[i][j]值。命名模型的正确方法是什么，以便我们也可以在控制器中设置其值？
我将HTML代码更改为：
<table id="lotTable" ng-table="tableSorting" class="table table-striped table-bordered table-vmiddle">
<thead>
<tr>
<th ng-hide="true"></th>
<th>S No.</th>
<th>Lot No.</th>
<th>Lot Qty</th>
<th>Unit Cost</th>
<th>Lot Details</th>
<th>Trx Qty</th>
<th ng-hide="true">Balance</th>
<th>Balance</th>
</tr>
</thead>
<tbody ng-if="isDataLot=='yes'" ng-repeat-start="l in lotData track by $index" ng-init="parentIndex = $index" id=parentRow{{$index}} data-id="{{l.lotNo}}">
<tr ng-repeat="k in l track by $index" ng-init="lotDataChildIndex = $index">
<td header-class="'text-center'" ng-hide="true">

<input type="checkbox" class="checkhead" id="lotHiddenCheckbox{{parentIndex}}{{lotDataChildIndex}}">

为了在控制器中获取它，我使用了以下代码：
var quantity = $scope.lotDetailsValues[parentIndex+ '' +childIndex+ '' +index];
