我正在使用Angular4应用程序，在这里我有一个旋转木马，我展示产品和产品名称和价格。目前我有6个产品（3 + 3）。如果我点击左侧旋转木马将有2个按钮将显示右侧按钮右侧的3个产品将显示右侧的3个产品。
问题是当我添加新产品轮播时会生成一个新行，而不是像产品系列那样显示。
如何解决是。

在stackblitz中，没有添加新产品的按钮。要么手动添加新产品，要么从解决方案中遗漏代码。
如果手动添加，可能是将其添加为新行而不是其他列。由于您使用的是bootstrap布局，因此您的代码将屏幕区域分为12个部分，每个图像使用4个部分（分别为sm-12，sm-4）。现在，当您添加另一个产品时，会创建一个新行，因为当前行中没有剩余空间。
要解决这个问题，而不是按部分分配，给每个产品卡一个固定的尺寸，然后让整个滚动水平。
或者，创建另一个sm-12行（第3个carousal）并向其添加元素。您将需要创建一个托管3个产品的组件，每个左/右按钮将在主要的托盘中循环。任何产品添加都将放入空组件中，一旦填充，将创建另一个实例来托管产品。
---下面的伪代码，用实际值自定义----
@Component( {} }
export class ProductsContainerComponent {
products: Product[]
// template shows 3 products
}
@Component()
export class ProductCarousalComponent {
carousal: ProductsContainerComponent[]
btnPrevious, btnNext: Button => Each set the current pointer to a given container in list, which gets displayed
addNewProduct() {
ProductsContainerComponent container;
carousal.each(prod => if (prod.products.length < 3) { container = prod; break; } );
if (container == null)
{ container = new ProductsContainerComponent(); carousal.push (container); }
// construct your new product here (url, images, text etc)
container.products.push (new Product() );
}
