What is the best way to design an angular directive or service specifically for straightforward pagination featuring only next and previous options?

Within a block of div tags, an ng-repeat directive is being used to display sets of 3 divs at a time. By clicking on the next button, the next set of 3 divs should be displayed, and the same goes for the previous button.

Check out the HTML code below:

<div ng-click="">next</div>
<div ng-click="">prev</div>
<div ng-repeat="event in events" ng-hide="$index>2"> 
<div class="event-description">{{event.description}}</div> 
<span class="event-time">{{event.time}}</span> 
<span class="event-product">{{event.product}}</span>
</div>

Answer №1

If you're looking to incorporate a similar feature, consider the following approach:

$scope.hiddenIndex = 0;

$scope.next = function() {
    $scope.hiddenIndex += 3;
    if ($scope.hiddenIndex >= $scope.events.length) {
        $scope.hiddenIndex = 0;
    }
};

To utilize this in your HTML code, follow these steps:

<div ng-repeat="event in events" 
     ng-hide="$index < hiddenIndex || $index >= hiddenIndex + 3">
    <!-- ... -->
</div>
