How can I change a selected TAB with [Previous], [Next] buttons using type script function-CodePudding

How can I switch tabs using previous and next buttons in angular type sript. Below I'm written some sample code, I don't know how to sync between buttons and tabs.

Sample code:

<div>
  <ng-container>
      <tabset>
        <tab>
          <ng-template tabHeading>
            <span title="Flash mobile">Flash</span>
          </ng-template>
          <p> Flashing mobile </p>
        </tab>
        <tab>
          <ng-template tabHeading>
            <span title="Restore mobile">Restore</span>
          </ng-template>
          <p> Restore mobile </p>
        </tab>
      </tabset>
    </ng-container>
 </div>

<div>
<button class="btn" (click)="updatePrev()"> Previous </button>
<button class="btn" (click)="updateNext()"> Next </button>
</div>

If you are using bootstrap tab, you can provide ids to your tabs. Reference your tabset component using template reference variable and use the select method to select the tabs by id. Refer the sample code below:

<ngb-tabset #t="ngbTabset">
  <ngb-tab id="tab-selectbyid1" title="Simple">
    <ng-template ngbTabContent>

</ngb-tabset>

<p>
  <button class="btn btn-outline-primary" (click)="t.select('tab-selectbyid2')">Selected tab with "tab-selectbyid2" id</button>
</p>

Please check this solution as per your example, with some minor changes.

Change 1: Added Id's to each tabs. So that each Tabs will have unique id's

<tab>
   <ng-template tabHeading>
    <span title="Restore mobile">Restore</span>
   </ng-template>
   <p> Restore mobile </p>
</tab>

<tab id="1">
  <ng-template tabHeading>
    <span title="Restore mobile">Restore</span>
  </ng-template>
 <p> Restore mobile </p>
</tab>

During Next and previous operations, the IDs will be added/subtracted by one. The below Stackblitz sample with more than two tabs is self-explanatory. The sample is developed upon ngx-bootstrap.
