ngx-画廊不显示图像

Question

I am using @ngx-gallery/lightbox to display an image gallery. But it does not display any images. This I provide some code and Stackblitz demo as your reference

HTML

<button mat-button (click)="lightbox.open(0, 'lightbox')">Open Gallery</button>

Component

 items: GalleryItem[];

  constructor(public gallery: Gallery, public lightbox: Lightbox) {

  }
 ngOnInit() {
    // This is for Basic example
    this.items = imageData.map(item => {
      return new ImageItem(item.srcUrl, item.previewUrl);
    });

    // This is for Lightbox example
    this.gallery.ref('lightbox').load(this.items);
  }

}

Answer 1

The issue is that the ImageItem class expects a single parameter in form of an object.

This should fix your issue:

this.items = imageData.map(item => {
      return new ImageItem({ src: item.srcUrl, thumb: item.previewUrl });
    });

Answer 2

Seems like you have not initialised ImageItem properly, try this

this.items = imageData.map(item => new ImageItem({ src: item.srcUrl, thumb: item.previewUrl }));

instead of

this.items = imageData.map(item => {
      return new ImageItem(item.srcUrl, item.previewUrl);
    });

I'm not sure what api u were reading from, but according to their official api , this demo should work
