我正在开发我的 MVConlineShop 项目，这是我目前所做的：

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其中的产品，它将显示它们而不是如图所示，第一个产品和第二个产品，请知道这是如何完成的吗？我已经检查了Ajax，但它会为我做这个吗？这是我的_Layout.cshtml：

S.O.不是人们为您工作的地方。在寻求帮助之前至少需要付出一些努力，如果尝试后遇到问题，那么您可以寻求帮助
我知道，但是你能告诉我如何制作它的过程，我应该做什么步骤，我会做@Louis-RochTessier
请转到以下链接并学习 AjaxLink，据我所知，这将完全符合您的目标。 c-sharpcorner.com/UploadFile/abhikumarvatsa/…

标签： javascript html ajax asp.net-mvc partial-views

【解决方案1】：

您使用一个 URL 创建链接，该 URL 路由到您的 Category/Product 控制器中的操作（取决于您如何分解它），并带有一个 id、slug 或其他唯一标识该类别的东西。

然后，您可以使用此标识符来查找类别或与该类别相关的所有产品。同样，有多种方法可以解决这个问题，所以这取决于你想要什么。如果您查找类别，您会希望同时使用 Include 热切加载相关产品。

然后，您可以将产品类别/列表直接返回到视图，或者您可能希望先映射到视图模型。如果你走第二条路线，你只需返回你的视图模型。

【解决方案2】：

正确的做法是

创建部分视图以加载类别
创建局部视图以加载产品
创建一个索引视图并在索引中加载两者
使用 ajax 在类别点击上更新产品视图

【讨论】：

仅供参考，在布局中做所有事情都不是正确的方法。布局适用于应用程序通用的页眉、页脚和菜单等
是的，我知道，我有类、视图和控制器，但是这些类别在 _Layout.cshtml 中使用它们是错误的？ @克里希纳
不是这样的，如果一个页面到另一个页面之间发生变化，那么你不应该保持布局。假设您的菜单显示关于、联系方式等，您会在这些页面中显示类别吗？这就是为什么不应该存在类别的原因
但我想继续在左侧显示类别，这就是我在 _Layout.cshtml 中使用它的原因，这是正确的吧？ @克里希纳
