Angular 无法循环通过角度为的对象的对象的对象

我试图循环一个对象的一个对象的一个对象的一个对象。因此，基本上，对象层次结构是

FundClassViewModel
FundDetailsViewModel
FundClassDetailsViewModel

我需要打印FundClassDetailsViewModel的值

目前我没有收到错误消息，但也没有打印值。我只能看到正在打印的列标题

<div *ngIf="FundClasses && FundClasses.FundDetailsViewModel"> 
<!-- <div *ngIf="fundClassKeys">  -->
    <!-- {{fundClassKeys.length}} -->
    <table class="fundClassesTable" id="toggled-element">

        <tr>
            <td class="tableItem bold">Accounting Class Name</td>
            <td class="tableItem bold">Class ID</td>
            <td class="tableItem bold">Legal Fund Class</td>
            <td class="tableItem bold">Inception Date</td>
            <td class="tableItem bold">Invested Amount</td>
            <td class="tableItem bold">Vehicle Type</td>
            <td class="tableItem bold">Closure Status</td>
            <td class="tableItem bold">Is Side Pocket?</td>
            <td class="tableItem bold">Is Thematic?</td>
            <td class="tableItem bold">Codency Class?</td>
        </tr>

        <tr *ngFor="let fundClass of FundClasses | keyvalue" class="rowItem">
            <td class="tableItem">{{fundClass.value.Description}}</td>
            <td class="tableItem">{{fundClass.value.Id}}</td>
            <!-- <td class="tableItem">{{fundClass}}</td>
        <td class="tableItem">{{fundClass}}</td>
        <td class="tableItem">{{fundClass}}</td>
        <td class="tableItem">{{fundClass}}</td>
        <td class="tableItem">{{fundClass}}</td>
        <td class="tableItem">{{fundClass}}</td>
        <td class="tableItem">{{fundClass}}</td> -->
        </tr>


    </table>
</div>

你可以试试这些方法

<div *ngFor="let fundClass of FundClasses.FundDetailsViewModel" class="rowItem">
   <tr *ngFor="let f of fundClass['FundClassDetailsViewModel'] | keyvalue">
      <td class="tableItem">{{ f.value.Description}}</td>
      <td class="tableItem">{{f.value.Id}}</td>
  </tr>
</div>

{{f.value.Description}
{{f.value.Id}

应在MyResponse.FundDetailsViewModel.FundClassDetailsViewModel上提供。

<div *ngFor="let fundClass of FundClasses.FundDetailsViewModel" class="rowItem">
   <tr *ngFor="let f of fundClass['FundClassDetailsViewModel'] | keyvalue">
      <td class="tableItem">{{ f.value.Description}}</td>
      <td class="tableItem">{{f.value.Id}}</td>
  </tr>
</div>
