Dynamic Tab + bootstrap + angular5 - node.js

Question

I am new to Front-End and angular part. I need to load tabs dynamically from what it returned from Backend...
Consider i am getting an array as like below :
*["tab1","tab2","tab3"].*
I have show tabs in a page with tab1, tab2, tab3.
What i have tried is hardcoded , its working,
<div class="nav-tabs-custom">
<ul class="nav nav-tabs" >
<li class="active"><b>tab1</b></li>
<li><b>tab2</b></li>
<li><b>tab3</b></li>
<li><b>tab4</b></li>
</ul>
</div>
<div class="tab-content">
<div class="tab-pane active" id="tab_1"> </div>
<div class="tab-pane active" id="tab_2"> </div>
<div class="tab-pane active" id="tab_3"> </div>
<div class="tab-pane active" id="tab_4"> </div>
</div>
Also i have to make sure that on click of the tab it should call a method with clicked name. All should be dynamic. Please suggest your ideas.Thanks.

Answer 1

you have to change href="#id" to data-target="#id"
<div class="nav-tabs-custom">
<ul class="nav nav-tabs" >
<li class="active"><a data-target="#tab_1" data-toggle="tab" (click)="loadData('abc')"><b>tab1</b></a></li>
<li><a data-target="#tab_2" data-toggle="tab" (click)="loadData('xxx')"><b>tab2</b></a></li>
<li><a data-target="#tab_3" data-toggle="tab" (click)="loadData('xyz')"><b>tab3</b></a></li>
<li><a data-target="#tab_4" data-toggle="tab" (click)="loadData('fgfgfg')"><b>tab4</b></a></li>
</ul>
</div>
<div class="tab-content">
<div class="tab-pane active" id="tab_1"> </div>
<div class="tab-pane active" id="tab_2"> </div>
<div class="tab-pane active" id="tab_3"> </div>
<div class="tab-pane active" id="tab_4"> </div>
</div>

I achieved such functionality using ngx-Bootstrap
Array of tabs:
tabs: any[] = [{
title: 'Dynamic Title 1',
content: 'Dynamic content 1'
},
{
title: 'Dynamic Title 2',
content: 'Dynamic content 2'
},
{
title: 'Dynamic Title 3',
content: 'Dynamic content 3',
removable: true
}
];
Display tabs:
<tabset>
<tab heading="Static title">Static content</tab>
<tab *ngFor="let tabz of tabs"
[heading]="tabz.title"
[active]="tabz.active"
(select)="tabz.active = true"
[disabled]="tabz.disabled"
[removable]="tabz.removable"
(removed)="removeTabHandler(tabz)"
[customClass]="tabz.customClass">
{{tabz?.content}}
</tab>
</tabset>

So, there are different ways of implementing it. One way as suggested by #Comann will definitely work. The other way of doing the same thing would be installing bootstrap dependency - try doing
npm install --save bootstrap
Import this in your styles.css file
#import '~bootstrap/dist/css/bootstrap.css';
You can also import it in your angular.json file assuming you might have generated the project using angular-cli. I prefer it to be in styles.css.
Create a separate navbar component and in the template
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" routerLink="/route1">Route1<span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" routerLink="/route2">Route 2</a>
</li>
</ul>
</div>
</nav>
<router-outlet></router-outlet>
Instead of having the two router links hard coded you will loop around with *ngFor on the array of tabs and populate it. Hope this helps.
