    <img [src]="getImageUrl(image, true);" *ngFor="let image of sampleImages" [ERROR ->](click)="openSampleImage(image)">
</div>")

html代码是

    <div class="samples" *ngIf="sampleImages" >
    <img [src]="getImageUrl(image, true);" *ngFor="let image of sampleImages" (click)="openSampleImage(image)">
</div>

，组件代码为：

public getImageUrl(image: SampleImage, useThumbnail = false) : string {
    const url = (image.thumbnail && useThumbnail) ? image.thumbnail : image.url;
    // prefix relative link with base url, if needed
    if (url.indexOf('//') === -1) {
        return this.config.getAssetUrl(url);
    } else {
        return url;
    }
}
