The Problem is when I start my angular application the image slider using bootstrap carousel is working fine. But when I routing to the other view and coming back to the image slider view it's not auto sliding and also I can use next and prev button to change the images but it is not auto-sliding. It works only when I reload the page. How to solve this ? Here is my code .html file <div id="myCarousel" class="carousel slide carousel-fade" data-bs-ride="carousel" data-bs-pause="false"> <!-- CAROUSEL INDICATORS --> <div class="carousel-indicators"> <div *ngFor="let image of images;index as i;first as isFirst" [class.active]="isFirst"> <button type="button" data-bs-target="#myCarousel" [attr.data-bs-slide-to]="i" aria-current="true"> </button> </div> </div> <!-- CAROUSEL IMAGES --> <div class="carousel-inner"> <div class="carousel-item active" data-bs-interval="2000" *ngFor="let image of images;first as isFirst" [class.active]="isFirst"> <img id="carouselImage" src="{{image}}" class="d-block w-100" height="707vh" alt=""> <div class="carousel-caption d-none d-md-block"> <h3>It Differentiates Your Brand From Others</h3> <p>Kajah Industrial is The leading Industrial In The Country.</p> <button class="btn" (click)="btnService()">Watch Our Services</button> </div> </div> </div> <!-- NEXT AND PREV BUTTON --> <button class="carousel-control-prev" type="button" data-bs-target="#myCarousel" data-bs-slide="prev"> <span class="carousel-control-prev-icon" aria-hidden="true"></span> <span class="visually-hidden">Previous</span> </button> <button class="carousel-control-next" type="button" data-bs-target="#myCarousel" data-bs-slide="next"> <span class="carousel-control-next-icon" aria-hidden="true"></span> <span class="visually-hidden">Next</span> </button> </div> .ts file import { bootstrap } from 'bootstrap'; ... ngOnInit() { var myCarousel = document.querySelector('#myCarousel') var carousel = new bootstrap.Carousel(myCarousel) } angular.json file "styles": [ "node_modules/bootstrap/dist/css/bootstrap.min.css", "node_modules/font-awesome/css/font-awesome.min.css", "./node_modules/aos/dist/aos.css", "src/styles.css" ], "scripts": ["./node_modules/jquery/dist/jquery.min.js", "./node_modules/popper.js/dist/umd/popper.min.js", "./node_modules/bootstrap/dist/js/bootstrap.min.js", "./node_modules/aos/dist/aos.js" ] And also I found this error in the console *ERROR TypeError: Cannot read property 'Carousel' of undefined at HomeComponent.ngOnInit * Continue reading...
