html - 以 Angular 6 动态创建 html 导航标签

Question

我对 angular 6 很陌生，我在 HTML 中创建了选项卡，我需要将它转换为 angular 6 并使其动态化。下面是我的 HTML 代码-

<ul class="nav nav-tabs side_nav" role="tablist">
  <li role="presentation" class="dashboard_li active">
     <a href="#one" class="coin_name" aria-controls="one" role="tab" data-toggle="tab"></a>
  </li>
  <li role="presentation" class="dashboard_li">
    <a href="#two" class="coin_name" aria-controls="two" role="tab" data-toggle="tab"></a>
  </li>
</ul>
<div class="tab-content">
  <div role="tabpanel" class="tab-pane active" id="one"></div>
  <div role="tabpanel" class="tab-pane active" id="two"></div>
</div>

我已将其转换为 angular 6，以下是我的 angular 代码 -

<ul class="nav nav-tabs side_nav" role="tablist">
  <li *ngFor="let wallet of coinwallet; let first = first;" [ngClass]="{firstItem: first}" role="presentation" class="accounts_li" [class.active]="selectedwallet===wallet">
    <a (click)="selectedwallet = coinwallet" aria-controls="one" role="tab" data-toggle="tab"></a>
  </li>
</ul>

<div class="tab-content">
  <div role="tabpanel" class="tab-pane active" id="one"></div>
  <div role="tabpanel" class="tab-pane active" id="two"></div>
</div>

现在我这里有两品脱——
1- 我将如何根据标签使标签内容动态化
2- 当前选项卡不起作用，因为我正在从一个选项卡更改为另一个选项卡，选项卡内容始终保持不变，不会根据选项卡更改。
任何帮助，将不胜感激。提前致谢。

您需要使用 *ngIf 显示/隐藏标签内容 Angular Directive(指令)

<ul class="nav nav-tabs side_nav" role="tablist">
  <li *ngFor="let wallet of coinwallet; let first = first;" [ngClass]="{firstItem: first}" role="presentation" class="accounts_li" [class.active]="selectedwallet===wallet">
    <a (click)="selectedwallet = wallet" aria-controls="one" role="tab" data-toggle="tab">{{wallet}}</a>
  </li>
</ul>

<div class="tab-content">
  <div *ngIf="selectedwallet === coinwallet[0]" role="tabpanel" class="tab-pane active" id="one">wallet 1 content</div>
  <div *ngIf="selectedwallet === coinwallet[1]" role="tabpanel" class="tab-pane active" id="two">wallet 2 content</div>
</div>

.ts:

  coinwallet: string[] = ['wallet1','wallet2'];
  selectedwallet = this.coinwallet[0];
