如何使用路由到操作的URL创建链接（MVC）
我正在开发 MVConlineShop 项目，这是我到目前为止所做的：
我的SQL server中有类别和产品的数据库，现在我想按任何类别来显示产品，它会显示它们而不是图像中所示的第一个产品和第二个产品，对于如何做到这一点的任何想法，请检查Ajax，但它会为我做这个吗？
这是我的_Layout.cshtml：

答案 0 :(得分：1)
正确的方法是
- 创建部分视图以加载类别
- 创建部分视图以加载产品
- 创建索引视图并在索引 中加载
- 使用ajax更新类别点击产品视图
答案 1 :(得分：1)
使用id，slug或其他唯一标识该类别的内容，您可以使用URL创建链接，该URL会路由到类别/产品控制器中的操作（具体取决于您如何分解它）。
然后，您可以使用此标识符查找类别或与该类别相关的所有产品。同样，您可以通过多种方式解决这个问题，因此这取决于您的需求。如果您查找该类别，则需要使用Include同时热切地加载相关产品。
然后，您可以将产品的类别/列表直接返回到视图，或者您可能希望首先映射到视图模型。如果你走第二条路线，你只需返回你的视图模型。
