Javascript 如何在引导ngb选项卡集的angular 6中以编程方式加载选项卡

我想使用angular 6 typescript以编程方式加载选项卡。当前，当我单击选项卡时，它会加载。一、 要通过代码加载。这是我尝试过的示例代码，但仍然在单击选项卡时加载

<ngb-tabset #t="ngbTabset" [activeId]="activeIdString" (tabChange)="tabChangeEvent($event)">
  <ngb-tab title="Workforce Plan-Headcount" id="wf1">
    <ng-template ngbTabContent>
      <app-workforce-plan-headcount></app-workforce-plan-headcount>
    </ng-template>
  </ngb-tab>
  <ngb-tab title="Workforce Plan-Cost" id="wf2">
    <ng-template ngbTabContent>
      <app-workforce-plan-cost></app-workforce-plan-cost>
    </ng-template>
  </ngb-tab>
  <ngb-tab title="Current Vacancies" id="wf3">
    <ng-template ngbTabContent>
      <app-current-vacancies></app-current-vacancies>
    </ng-template>
  </ngb-tab>
  <ngb-tab title="Data Entry" id="wf4">
    <ng-template ngbTabContent>
      <app-data-entry></app-data-entry>
    </ng-template>
  </ngb-tab>
</ngb-tabset>

我尝试了这段代码，它在第一次加载时加载第三个选项卡。然后它不会加载第三个选项卡。是否有最好的方式以编程方式加载选项卡

这是我的有效解决方案，可能对其他人有用

<ngb-tabset #t="ngbTabset" (tabChange)="beforeChange($event)">

public beforeChange($event: NgbTabChangeEvent) {
        if (condition) {
        // prevent from loading
            $event.preventDefault();   
        }
    else{
        this.t.select($event.nextId);
    }
    }
