Angularjs 如何从嵌套的ng repeat中获取值

我的问题是如何在第二次ng重复中获取数据，如下面给出的循环示例所示

例如：

ng-repeat="question in questions"
{{$index+1}}
ng-repeat="option in  question.choiceBeanList"
{{questionObj.questionId}} --> Here I have to get both data's

您可以使用ngInit进行此操作

检查文档：

如果您只是想获取索引，可以使用$parent.$index

Json模型

<div ng-repeat="innerList in list" ng-init="outerIndex = $index">
  <div ng-repeat="value in innerList" ng-init="innerIndex = $index">
     <span class="example-init">list[ {{outerIndex}} ][ {{innerIndex}} ] = {{value}};</span>
  </div>
</div>

嵌套ng重复序列

  $rootScope.makes = [
    {
      name: 'BMW',
      models: ['335i', 'M3', 'M4']
    },
    {
      name: 'Mercedes',
      models: ['C250', 'E350']
    }
  ];

工作

尝试以下方法：

<ul ng-repeat="make in makes">
  <li ng-repeat="model in make.models">
    ({{$parent.$index}},{{$index}}): {{make.name}} {{model}}
  </li>
</ul>

希望它能帮助

您可以像这样传递外部ng重复数据

<div ng-repeat="question in questions">
  <div ng-repeat="option in  question.choiceBeanList">
    {{questions.indexOf(question)}}   // To get the index value of FIRST ng-repeat
    {{$index}}  // To get the index value of current ng-repeat 
  </div>
</div>

使用ng init，如下所述：

<div ng-repeat="question in questions">
  <div ng-repeat="option in  question.choiceBeanList">
    {{questions.indexOf(question)}}   // To get the index value of FIRST ng-repeat
    {{$index}}  // To get the index value of current ng-repeat 
  </div>
</div>

<div ng-repeat="question in questions">
   <div ng-repeat="option in question.choiceBeanList">
      {{$parent.$index+1}}_{{$index}}
   </div>
</div>
