Change the $index value during every iteration within ng-repeat

Question

Change the $index value during every iteration within ng-repeat

After each iteration of ng-repeat in angularjs, I need to increment the $index value. I attempted to do so using ng-init in this way, but unfortunately it didn't work as expected and incremented at the start of the ng-repeat loop. Can someone provide guidance on how to achieve this?

   

 <div class ="row" ng-repeat ="offer in offers track by $index" ng-init="$index=$index+5">
    <div class="col-md-6">
   <span>offers[$index].title</span>
    <span>offers[$index+1].title</span></div>
    <div class="col-md-4"><span>offers[$index+2].title</span>
    <span>offers[$index+3].title</span>
    <span>offers[$index+4].title</span></div>
    </div>

The issue arises when trying to display two titles alternatively in the first row, and then three other titles in the next row during a second iteration. The duplication occurs because of the $index value being 2. Therefore, there is a need to adjust the $index value to ensure that the titles are displayed in the correct order.

Answer №1

In AngularJs, there is a provision to provide an index value for each iteration. This index value can be utilized to modify the count accordingly.

<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>

<body ng-app="myApp" ng-controller="myCtrl">
Count =  {{count}}
<h1 ng-repeat="x in records  track by $index">{{x}} {{$index}} Count : {{count+$index}}</h1>

<script>
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
  $scope.count = 5;

  $scope.records = [
    "Iteration : ",
"Iteration : ",
  "Iteration : ",
"Iteration : ",
  ]
});
</script>

</body>
</html>
