javascript - AngularJS 多维数组

Question

我正在寻找一种方法来将范围内的三维数组中的数据与我的视图绑定..

我的范围（短版）看起来像这样

$scope.publicationData = [ 
    { pubId:'1' , pubName:'Level 1 A' , pubCat:[
        { pubCatId:'1' , pubCatName:'Level 2 A', pubSubCat:[ 
            { pubSubCatId:'1' , pubSubCatName:'Level 3 A' }, 
            { pubSubCatId:'2' , pubSubCatName:'Level 3 B' }
            ]
        },
        { pubCatId:'2' , pubCatName:'Level 2 B', pubSubCat:[
            { pubSubCatId:'3' , pubSubCatName:'Level 3 C' },
            { pubSubCatId:'4' , pubSubCatName:'Level 3 D' }
            ]
        }
        ]
    }];

在视图中，我的代码成功呈现了第一个和第二个数组维度中的内容，但我无法从 pubSubCatId 或 pubSubCatName 获取值

HTML + 角度视图

<div ng-controller="myPublictionCtrl">

<div ng-repeat="publication in publicationData">

    <ul>
        <li >
                            <!-- This works -->
            {{publication.pubId}}. {{publication.pubName}}
        </li>
    </ul>

    <ul>
                    <!-- This works -->

        <li ng-repeat="category in publication.pubCat">
            {{category.pubCatId}}. {{category.pubCatName}}
        </li>

    </ul>

    <ul>
                    <!-- This doesn't work -->

        <li ng-repeat="subcategory in publication.pubCat.pubSubCat">
            {{subcategory.pubSubCatName}}
        </li>
    </ul>
</div>
</div>

我将如何从范围的更深层次检索数据。AngularJS 可以做到这一点吗？

Answer 1

第三个循环必须嵌套在第二个循环内，并使用

subcategory in category.pubSubCat

Answer 2

<div ng-controller="myPublictionCtrl">
        <div ng-repeat="publication in publicationData">
            <ul>
                <li style="text-align:left">                       
                    {{publication.pubId}}. {{publication.pubName}}
                </li>
            </ul>
            <ul>
                <li ng-repeat="category in publication.pubCat" style="text-    align:left">{{category.pubCatId}}. {{category.pubCatName}}               
                <ul> 
                <li ng-repeat="subcategory in category.pubSubCat" style="text-align:left">{{category.pubCatId}}.{{subcategory.pubSubCatId}}.     {{subcategory.pubSubCatName}}
                </li>
                </li>
                </ul>
            </ul>
        </div>
    </div>
