Utilizing the ng-if directive to choose the second element within an iteration of an ng-repeat loop

I am currently working on a project where I need to organize and group content by day. While the grouping function is working fine, I am facing an issue with treating the first two items in the loop differently from the rest. I have experimented with using ng-if in the code snippet below, with conditions like ng-if="$first || $index == 1" and ng-if="!$first || !$index != 1", but it doesn't seem to be achieving the desired outcome.

Can anyone guide me on the correct method to select the first and second items in an ng-repeat loop?

<div class="col-sm-12 day-block" ng-repeat="(key,value) in article.items | groupBy:'posted|date: MMM:dd' | toArray:true ">
  <div class="col-sm-2 timestamp">
    <h3>March 9</h3>
    <h1>Day 4</h1>
  </div>
  
  <div class="col-sm-10" ng-repeat="article in value | orderBy:'posted' | unique: 'nid'">
      <div class="col-sm-12">
        <div class="row">
          <div class="col-xs-6" ng-if="$first || $index == 1">
            <span ng-class="blog-post-thumbnail" ng-bind-html="to_trusted(article.main_image)"></span>
            <h2 ng-bind-html="to_trusted(article.node_title)"></h2>
            <h4 ng-bind-html="to_trusted(article.author)"></h4>
            <h4 ng-bind-html="to_trusted(article.posted)"></h4>
         </div>

         <div class="row" ng-if="!$first || $index != 1">
           <div class="col-xs-4">
             <span ng-class="blog-post-thumbnail" ng-bind-html="to_trusted(article.main_image)"></span>
           </div>

           <div class="col-xs-8">
             <h3 ng-bind-html="to_trusted(article.node_title)"></h3>
             <h4 ng-bind-html="to_trusted(article.author)"></h4>
           </div>
         </div>
     </div>
   </div>
  </div>
</div>

Answer №1

If you want your condition to be true for all indexes except 1, you can use the expression ng-if="!$first || !$index == 1". To specifically select the first and second indexes, you can try

ng-if="$index == 0 || $index == 1"
.

For all other indexes, you can try using

ng-if="!($index == 0 || $index == 1)"
.
