Accessing the i and i+1 elements within a ng-repeat iteration

I'm currently learning Angular and struggling with a seemingly simple issue. My goal is to achieve the following HTML structure in AngularJS:

<div>
  <div>
    {{bar[i]}}
    {{bar[i+1]}}
  </div>
  <div>
    {{bar[i+2]}}
    {{bar[i+3]}}
  </div>
</div>

My attempt involves iterating over my model using ng-repeat in this manner:

<div ng-repeat="bar in bars">
  <div>
    <div ng-include="bar.html"></div>
    <div ng-include="bar.html"></div>
  </div>
</div>

The problem arises from both ng-include referencing the same variable bar.

Is there a way to access elements at index i and

i+1</code within a <code>ng-repeat
loop?

Any help would be appreciated!

Answer №1

To access the current index, you can utilize $index:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app>
  <div ng-repeat="foo in ['x','y','z']">
    <div>
      <h1>Item: {{foo}}</h1>
      <div>{{$index*2}}</div>
      <div>{{$index*2+1}}</div>
    </div>
  </div>
</div>

You can also incorporate ng-include in this manner:

<div ng-include="items[$index*2].html"></div>
<div ng-include="items[$index*2+1].html"></div>
