Description
const createImageWithFallback = (options: any, fallbackImage?: string) => {
const image = createImage({ image: defaultImage, ...options});
(image as any).failCallback = () => {
image.setAttribute('image', fallbackImage || defaultImage);
};
return image;
}
export default createImageWithFallback;
直接设置也不生效，加载还是显示默认的图
