当我下降到使用 ng-repeat 创建的元素时如何向下滚动

Question

我有一个用 ng-repeat 创建的列表和两个向上或向下按钮。用户可以选择列表的任何元素并使用两个按钮向上或向下。

当我使用向下按钮下降所选元素时，滚动条仍然固定我无法再看到所选元素。

我想在元素隐藏时向下滚动。

        <div class="panel-body panelBodySelectedData" style="padding-left: 10px">
        <nav>
            <ul ng-repeat="item in resultJson.items" class="nav nav-pills nav-stacked span2">
                <li class="itemReporting" ng-click="selectItem($index)"  ng-class="{selectedReportingItem: $index==selectedIndex}" >{{item.label}}</li>
            </ul>
        </nav>
    </div>


$scope.goUp = function(){
    if($scope.selectedIndex > 0){
        console.log('goUp');
        $scope.aux = $scope.resultJson.items[$scope.selectedIndex];
        $scope.selectedIndex -- ;
        $scope.resultJson.items[$scope.selectedIndex+1] = $scope.resultJson.items[$scope.selectedIndex];
        $scope.resultJson.items[$scope.selectedIndex] = $scope.aux;
    }
};

$scope.goDown = function(){
    if($scope.selectedIndex < $scope.resultJson.items.length -1){
        console.log('goDown');
        $scope.aux = $scope.resultJson.items[$scope.selectedIndex];
        $scope.selectedIndex ++ ;
        $scope.resultJson.items[$scope.selectedIndex-1] = $scope.resultJson.items[$scope.selectedIndex];
        $scope.resultJson.items[$scope.selectedIndex] = $scope.aux;
        $location.hash('bottom');

          // call $anchorScroll()
          $anchorScroll();

    }
};
