Question

我试图循环一个对象的一个对象。所以基本上对象层次是

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。我只能看到列标题被打印

<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>

FundClass组件

export class FundClassesComponent implements OnInit {

    //@Input() FundClasses;
    private _fundClasses : any;
    public fundClassKeys = [];


    public get FundClasses(): any {
        return this._fundClasses;
    }
    @Input()
    public set FundClasses(value: any) {
        this._fundClasses = value;
    }

    ngOnInit() {
        this.init();
    }

    init() {
        // if(this.FundClasses) {
        // this.fundClassKeys = Object.keys(this.FundClasses.FundDetailsViewModel.FundClassDetailsViewModel);
       // }
    }
}

Answer 1

您可以尝试这些方式

<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>
