Question

我正试图让 owl carousel在Angular中工作。

我想在我看来这样做标记，因为我有很多画廊：

<owl-carousel owl-options="owlOptions">
  <div ng-repeat="image in gallery" class="item">
    <p>hello</p>
  </div>
</owl-carousel>

基本上所有指令应该做的是转盘的初始化。该指令完美无缺，除非我使用ng-repeat。我猜这个指令是在处理ng-repeat之前加载的。

有没有人对如何解决这个问题有任何想法，而不为每种类型的滑块构建模板和指令？

非常感谢你！

这是指令：

angular.module('dir.owlCarousel', [])
  .directive('owlCarousel',[function() {
    return {
      restrict: 'EA',
      transclude: false,
      scope: {
        owlOptions: '='
      },

      link: function(scope, element, attrs) {
        $(element).owlCarousel(scope.owlOptions);
      }

    };
  }]);

Answer 1

你想看看这些答案：

ng-repeat finish event

AngularJS event for when model binding or ng-repeat is complete?

angular.module('dir.owlCarousel', [])
  .directive('owlCarousel',[function() {
    return {
      restrict: 'EA',
      transclude: false,
      scope: {
        owlOptions: '='
      },
      link: function(scope, element, attrs) {
          scope.initCarousel = function() {
            $(element).owlCarousel(scope.owlOptions);
          };
        }
      }
    };
  }])
  .directive('owlCarouselItem',[function() {
     return function(scope) {
     if (scope.$last) {
        scope.initCarousel();
     }
    };
  }]);

<owl-carousel owl-options="owlOptions">
  <div owl-carousel-item ng-repeat="image in gallery" class="item">
    <p>hello</p>
  </div>
</owl-carousel>

必须对您的指令进行一些更改，以便它可以在同一页面上使用多个轮播。以下是工作plnkr

的链接

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());
            }
        }
    };
}]);

Owl Carousel没有识别ng-repeat的元素
