高亮值angularjs

Question

我想通过以下方式获得结果，

预期工作流程图，

这是默认视图，

方案1：当单击数字“ 1”时，从左到右，孩子们需要如下所示突出显示

方案2：考虑方案1的结果，请从左到右单击数字“ 3”，子级需要删除如下所示的突出显示，因为3被我们视为父级/根级，< / p>

方案3：考虑默认视图，默认情况下没有选择当单击数字“ 18”时，所有父值都需要如下所示突出显示，

方案4：考虑方案3的结果，当仅对18单击数字“ 18”时，需要删除高亮显示，如下所示，不需要从右到左父级取消选择任何值。

注意：在单击任意值时，无需取消从右到左父级的选择。在这种情况下，只需单击值即可删除突出显示。

以下是代码：JSFiddle

 $scope.setActiveSelectedItem = function() {
 return $scope.groupOfCheckboxes[i].RowValues[j].isActive = !$scope.groupOfCheckboxes[i].RowValues[j].isActive;
    }

    $scope.setActivePrevNext = function(arr, id) {
     let keys = Object.keys(arr);
     let nextIndex = keys.indexOf(id) +1;
     let nextItem = keys[nextIndex];
     return $scope.groupOfCheckboxes[i].RowValues[nextIndex].isActive = !$scope.groupOfCheckboxes[i].RowValues[nextIndex].isActive;
    }

    $scope.setBinary = function (id) {

        for(i=0; i<$scope.groupOfCheckboxes.length; i++) {
          for(j=0; j<$scope.groupOfCheckboxes[i].RowValues.length; j++) {

             if($scope.groupOfCheckboxes[i].RowValues[j].td == id) { 
             $scope.setActiveSelectedItem();
             $scope.setActivePrevNext($scope.groupOfCheckboxes, id);

             } 

             }

        }


    }

});
