Question

Utilizing the powerful combination of AngularJS and Ionic, leverage the ng-repeat feature to seamlessly insert elements between

There are 2 loops in our code structure. They look like this:

<ion-list>
  <ion-item ng-repeat="pair in items">
      <div class="row">
          <ion-item ng-repeat="item in pair" class="col-45">
              {{item}}
          </ion-item>
      </div>
  </ion-item>
</ion-list>

I am looking to add an element between items in the second loop, specifically with a class of col-10. What would be the optimal approach to achieve this? Is there a way to modify ng-repeat to include a custom element between iterations? Or perhaps replace it with a traditional for loop?

The desired final layout is as follows:

<div class="row"> 
  <div class="col-45"></div>
  <div class="col-10"></div>
  <div class="col-45"></div>
</div>

UPD: The controller sends an array called pair containing [1,2]. The expected result should be:

<div class="row"> 
  <div class="col-45">1</div>
  <div class="col-10"></div>
  <div class="col-45">2</div>
</div>

Revised Solution:

After some consideration, I came up with a solution using jQuery without the need for additional divs. However, I am still exploring potential ways to achieve the same outcome in pure Angular, possibly through a directive or ng-include. Here is the revised approach:

<ion-list>
      <ion-item ng-repeat="(parentIndex, pair) in items">
          <div class="row">
              <ion-item ng-repeat="item in pair"
                        class="col-45 item-{{parentIndex}}-{{$index}}"
                        ng-init="insertAfter(parentIndex, $index)">
                  {{item}}
              </ion-item>
          </div>
      </ion-item>
  </ion-list>

In the controller, you would have something like this:

$scope.items = [
   [ "someValue", "someOtherValue" ],
   [ "someValue", "someOtherValue" ]
];

$scope.insertAfter = function(parentIndex, index){
   if(index < $scope.items[parentIndex].length){
       $timeout(function(){
           jQuery( "<div class='col-10'> or maybe include a template here </div>" )
                 .insertAfter(".item-"+parentIndex+"-"+index );
       }, 0);
   }
};

If you intend to insert directives, it's essential to compile them first. Therefore, a directive that handles these actions would be preferable over relying solely on the controller.

Initial Approach:

Previous method was more of a quick fix rather than a comprehensive solution

<ion-list>
   <ion-item ng-repeat="pair in items">
       <div class="row some-container">
           <div ng-repeat="item in pair">
               <ion-item class="col-45">
                   {{item}}
               </ion-item>
               <div class="col-10"></div>
           </div>
       </div>
   </ion-item>
</ion-list>

.some-container div.col-10:last-child { display: none; }

Although the markup may not align precisely with your requirements, it could provide some assistance.

To implement conditional classes in AngularJS, you can leverage the $odd property with ng-class. Here is an example of how you can achieve this:

<ion-list>
 <ion-item ng-repeat="pair in items">
  <div class="row">
      <ion-item ng-repeat="item in pair" ng-class="{true:'col-45', false:'col-10'}[$odd]">
          {{item}}
      </ion-item>
  </div>

Alternatively, you can use ng-class-odd and ng-class-even directives for applying odd and even classes:

<ion-list>
 <ion-item ng-repeat="pair in items">
  <div class="row">
      <ion-item ng-repeat="item in pair" ng-class-odd="'col-45'" ng-class-even="'col-10'">
          {{item}}
      </ion-item>
  </div>
