Topic: carousel.component.ts line: 145 -- error message

jespenhain premium asked 5 years ago


Actual behavior After Upgrading from 7.5.2 to 7.5.3 the following error message is displayed in console: Cannot read property 'classList' of undefined at DefaultDomRenderer2.push../node_modules/@angular/platform-browser/fesm5/platform-browser.js.DefaultDomRenderer2.addClass (platform-browser.js:1102) at BaseAnimationRenderer.push../node_modules/@angular/platform-browser/fesm5/animations.js.BaseAnimationRenderer.addClass (animations.js:239) at DebugRenderer2.push../node_modules/@angular/core/fesm5/core.js.DebugRenderer2.addClass (core.js:28546) at CarouselComponent.push../node_modules/ng-uikit-pro-standard/fesm5/ng-uikit-pro-standard.js.CarouselComponent.ngAfterViewInit (ng-uikit-pro-standard.js:1410)

i realized the code which cause this problem is: (carousel.component.ts line: 145)

if (this.isControls) {
  this.carouselIndicators = this.el.nativeElement.querySelectorAll('.carousel-indicators > li');
  if (this.carouselIndicators.length && this.activeSlideIndex) {
    this.renderer.addClass(this.carouselIndicators[this.activeSlideIndex], 'active');
  } else {
    this.renderer.addClass(this.carouselIndicators[0], 'active');
  }
}

Resources (screenshots, code snippets etc.) `

    <mdb-carousel-item *ngFor="let item of imagesBasic" class="carousel-inner">
        <div class="view w-100">
            <div class="carousel-items w-100 overlay zoom" (click)="openImageModal(item.caption)"
                 [ngStyle]="{'background-image': 'url(' + item.img + ')','background-position': 'center center','height': '200px'}">
            </div>
        </div>
    </mdb-carousel-item>`

Hello,

Thank you for reporting this problem, we will take care of that.

Do you load the carousel data asynchronously?

This problem will be fixed in the next version of MDB Angular.
