Javascript 用复杂的JSON填充嵌套的ng repeat

我试图用AngularJS的ng repeat在另一个ng repeat中填充一行多个值的

td

。在我尝试访问第三个嵌套对象之前，它一直在工作

对象海卡希：

对象

-renewalUIs

--patentUI

--property.patentApplicationNumber（这是我想要访问的）

最初我是从一个

$开始的。每个
函数循环遍历每个对象，然后我遇到了这个线程，它解释了循环遍历数据更有效、更容易。我的问题是我可以访问
renewalUIs
的属性，但是当我向我的
ng repeat
语法添加额外对象时，不会显示任何数据

此代码适用于：

<tr ng-repeat="transaction in $ctrl.transactionHistory">
    <td>
        <span ng-repeat="item in transaction.renewalUIs">{{item.renewalDueDate}}<br></span> 
    </td>
</tr>

patentUI是每个renewalUI的财产吗

如果是这种情况，ng repeat将无法正常工作。您可以使用指令ng repeat来迭代集合对象（就像数组一样）

ngRepeat指令对一个模板中的每个项目实例化一次模板
收藏


因此，代码可能会起作用

<tr ng-repeat="transaction in $ctrl.transactionHistory">
    <td>
        <span ng-repeat="item in transaction.renewalUIs">{{item.patentUI.patentApplicationNumber}}<br></span>   
    </td>
</tr>


{{item.patentUI.patentApplicationNumber}

因为RenewalUI可能是一个数组？因此，您可能需要指定索引或使用一个或多个字符串，注意您没有任何JSON。你只有一个目标。JSON是一种字符串格式@谢谢。我会调查一下，你能发布你希望迭代的
事务
示例的JSON吗？这完全可能是因为结构与您尝试的不匹配。添加了JSON，尽管已经提供了解决方案。谢谢大家，谢谢@jmltalarn。有一个RenewalUI，两个PatentuIrenewalUI是一个数组，因此是可移植的。此数组中的对象具有属性parentUI并包含一个对象，它不是一个正确的数组，在这种情况下将不会被迭代。感谢您的反馈
