Question

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

我的问题是如何在第二个ng-repeat中获取数据，如下所示的循环示例。

例如：

for(i=0;i<=10;i++)
{
for(j=0;j<=5;j++)
{
console.log(i+"_"+j)
}
}

Answer 1

您可以将ngInit用于此

<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>

Answer 2

如果您只想尝试获取索引，可以使用$parent.$index

Json模型

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

嵌套ng-repeats

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

工作example

Answer 3

试试这个：

<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>

希望它有所帮助......！

Answer 4

您可以像这样传递外部ng-repeat数据

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