ngx画廊不显示图像

Question

我正在使用@ngx-gallery/lightbox显示图像库。但是它不显示任何图像。我提供一些代码和Stackblitz演示供您参考

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

我不确定您正在读取什么api，但according to their official api，this demo should work

Answer 2

问题是ImageItem类期望对象形式的单个参数。

这应该可以解决您的问题：

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

Answer 3

似乎您尚未正确初始化ImageItem，请尝试此操作

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

而不是

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