Using angularjs ng-repeat in combination with owl-carousel

<div class="owl-carousel">
    <div ng-repeat="items in itemlist"> 
        <a href="series.html"><img ng-src="{{items.imageUrl}}" /></a>
    </div>
    <div> 
      <a href="series.html><img src="http://placehold.it/350x150" /></a>
    </div>
 </div>

Take a look at the carousel here: Owl-carousel2

I have encountered an issue where applying the ng-repeat directive to the carousel causes the items to stack vertically instead of being arranged horizontally.

When I remove the ng-repeat and use static items, everything works as intended.

Is there a specific directive that I can write and apply to owl-carousel to maintain the horizontal layout?

What is it about ng-repeat that breaks the carousel?

Could Angular be removing the owl-carousel classes from the carousel somehow?

**Note**: If I manually build the list and then iterate through and append the elements using:

var div = document.createElement('div');
var anchor = document.createElement('a');
var img = document.createElement('img');            
.....       
carousel.appendChild(div);

and then call owl.owlCarousel({..}), it works. However, I'm not sure if this is the best workaround since ng-repeat makes everything easier.

I found a hack where if I wrap the owl init in a timeout, then ng-repat works.

setTimeout(function(){
      ...call owl init now  
},1000);

<link rel="stylesheet" href="css/owl.carousel.css"/>
<link rel="stylesheet" href="css/owl.theme.default.min.css"/>

.....
    <script src="/js/lib/owl.carousel.min.js"></script> 
        <script>
              $(document).ready(function() {
               var owl = $('.owl-carousel');
               owl.owlCarousel({
                 .....
               });
               owl.on('mousewheel', '.owl-stage', function(e) {
                 if (e.deltaY > 0) {
                   owl.trigger('next.owl');
                 } else {
                   owl.trigger('prev.owl');
                 }
                 e.preventDefault();
               });
             })

        </script>

Successfully adapted a directive created by DTing in another post to enable multiple carousels on the same page. Check out a functional example on this link

-- Update -- Included an additional plnkr to demonstrate how to add items. Performing a reinit() did not yield results because every time the owl carousel is destroyed, it loses the data-elements and cannot be initialized again.

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.items1 = [1,2,3,4,5];
  $scope.items2 = [1,2,3,4,5,6,7,8,9,10];
}).directive("owlCarousel", function() {
    return {
        restrict: 'E',
        transclude: false,
        link: function (scope) {
            scope.initCarousel = function(element) {
              // provide any default options you want
                var defaultOptions = {
                };
                var customOptions = scope.$eval($(element).attr('data-options'));
                // combine the two options objects
                for(var key in customOptions) {
                    defaultOptions[key] = customOptions[key];
                }
                // init carousel
                $(element).owlCarousel(defaultOptions);
            };
        }
    };
})
.directive('owlCarouselItem', [function() {
    return {
        restrict: 'A',
        transclude: false,
        link: function(scope, element) {
          // wait for the last item in the ng-repeat then call init
            if(scope.$last) {
                scope.initCarousel(element.parent());
            }
        }
    };
}]);

Answer №2

After experimenting with various directives without success, I stumbled upon a solution that may be considered somewhat of a hack, but it gets the job done.

Here is how my div was set up:

<div ng-repeat="item in mediaitems">
  <img ng-src="item.imageurl" />
</div>

The $scope.mediaitems data is fetched through an ajax call. I discovered that delaying the initialization of owl until after the list was populated ensured proper rendering. If you ever need to dynamically update your list, simply call the setupcarousel function (shown below) after the list has been updated to reinitialize the carousel.

It's worth noting that the carousel initialization is contained within an external file inside an anonymous function. This is just my personal preference, feel free to organize yours differently.

In my controller, I included something like this :

$scope.populate = function(){
     $timeout(function(){   
      $scope.mediaitems  = returnedlist;   //list of items returned from server
       utils.setupcarousel();              //invoke owl initialization
     });
};

var utils = (function(){
    var setupcarousel = function(){
        console.log('setting up carousel..');
         var owl = $('.owl-carousel');
         if(typeof owl.data('owlCarousel') != 'undefined'){
             owl.data('owlCarousel').destroy();
             owl.removeClass('owl-carousel');
         }

        owl.owlCarousel({
            loop: false,
            nav: true,
            margin: 10,
            responsive: {
              0: {items: 3 },
              600: {items: 5},
              960: { items: 8},
              1200:{items: 10},
              1600:{items: 12}
            }
          });
    };

    return{
      ....
    }

})();

The talented Angular UI Team has created a fantastic collection of bootstrap components in the form of angular directives. These components are not only visually appealing but also quick to implement. Plus, since they are directives, you won't encounter any compatibility issues with using jquery in an angular project. One particularly useful directive is their carousel component. You can access it here and here. I spent quite some time experimenting with carousels in angular projects. While I eventually managed to get the owl carousel working after much trial and error, the implementation by AngularUI is undeniably easier.

Similar to the response by JKOlaf, I have enhanced it with responsive design for improved user experience. Two key upgrades include:

  • Code that is fully responsive, enhancing UX across various devices.
  • The "autoHeight" property now manages smaller image thumbnails.

Here's the updated code snippet:


I was able to adapt a directive from DTing in another thread to work with multiple carousels on one page. Here's a functioning plnkr

-- Edit -- Another plnkr demonstrates adding an item. Reinit() didn’t work as destroying the owl carousel loses data- elements preventing reinitialization.

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.items1 = [1,2,3,4,5];
  $scope.items2 = [1,2,3,4,5,6,7,8,9,10];
}).directive("owlCarousel", function() {
    return {
        restrict: 'E',
        transclude: false,
        link: function (scope) {
            scope.initCarousel = function(element) {
              // Add preferred default options
                var defaultOptions = {
                };
                var customOptions = scope.$eval($(element).attr('data-options'));
                for(var key in customOptions) {
                    defaultOptions[key] = customOptions[key];
                }
                defaultOptions['responsive'] = {
                    0: {
                        items: 1
                    },
                    600: {
                        items: 3
                    },
                    1000: {
                        items: 6
                    }
                };
                $(element).owlCarousel(defaultOptions);
            };
        }
    };
})
.directive('owlCarouselItem', [function() {
    return {
        restrict: 'A',
        transclude: false,
        link: function(scope, element) {
            if(scope.$last) {
                scope.initCarousel(element.parent());
            }
        }
    };
}]);

You can adjust the responsive item counts based on your needs, setting lower values for larger image thumbnails. Hopefully, this solution proves helpful to others as well. Many thanks to the original contributor of this answer.
