我最近在onsen-ui上工作,当我试图在Tabbar和Navigator组件中引用Carrousel var(var="carousel")时,我遇到了困难。

代码一直有效,直到我尝试使用Tabs。我收到以下错误:

  

未捕获(承诺)TypeError:无法读取未定义的属性

我已经厌倦了'pageinit'解决方案,但似乎没有用。

这里是HTML。

                    <ons-icon icon="ion-ios-location" size="20px" fixed-width="true" ng-class="{'custom-icon': iconIndex == 'carouselWhere'}"></ons-icon>

            </ons-page>
        </ons-navigator>
    </ons-template>
</body>
</html>

和app.js

var module = ons.bootstrap('my-app', ['onsen']);

module.controller('AppCtrl',['$scope', function($scope) {

}]);

module.controller('carouselCtrl',['$scope', function($scope) {

    ons.ready(function() {

        $scope.iconIndex = $scope.carousel._attrs.$$element[0].children[$scope.carousel.getActiveIndex()].id;
        $scope.$apply();

        $scope.carousel.on('postchange', function (event) {
            $scope.iconIndex = $scope.carousel._attrs.$$element[0].children[$scope.carousel.getActiveIndex()].id;
            $scope.$apply()
        });

   });

}]);

你知道问题的来源吗?

非常感谢你的时间。

我在HTML中添加了一个标签,并将其放在codepen上。它似乎有用吗?你能说明收到错误后会发生什么吗?
