"Expand your list in AngularJS by automatically adding more items if the ng-repeat count is

I am struggling with this section of code. It currently shows a box with the first four linked resource images. However, I need it to display additional images if there are less than four. I tried looking for a solution, but couldn't find one.

<div class="collection_box" ng-repeat="i in collections">
    <div class="inner_collection_box">
        <div ng-repeat="r in i.resources || limitTo:4" class="collection_resource_image_div">
            <img class="collection_resource_image" src="/images/resource_images/{{ r.image }}" alt="{{ r.name }}" />
        </div>
        <strong>{{ i.name }}</strong>
    </div>
</div>

Answer №1

To enhance your view with additional images, consider using a filter. Your view code could be structured like this:

<div ng-repeat="r in i.resources | limitTo:4 | addImages">...</div>

The filter itself could be defined as follows:

yourApp.filter('addImages', function () {
  return function ($input) {
    var defaultImgs = [ ... ]; // your collection of default images

    if ($input.length < 4) {
      $input.concat(defaultImgs.slice(0, 4 - $input.length));
    }

    return $input;
});
