问题描述

我需要通过 Ajax 调用更新 Multiple ，我很困惑如何从 Controller Action 方法返回这些 Multiple 视图.

I need to update Multiple from an Ajax call , I am confused as in how to return these Multiple views from the Controller Action method.

推荐答案

你只能从一个函数返回一个值，所以你不能从一个操作方法返回多个部分.
如果您尝试将两个模型返回到一个视图，请创建一个包含您要发送的两个模型的视图模型，并使您的视图模型成为新的 ViewModel.例如

You can only return one value from a function so you can't return multiple partials from one action method.
If you are trying to return two models to one view, create a view model that contains both of the models that you want to send, and make your view's model the new ViewModel. E.g.

你的视图模型看起来像:

Your view model would look like:

public class ChartAndListViewModel 
{
   public List<ChartItem> ChartItems {get; set;};
   public List<ListItem> ListItems {get; set;};
}

那么您的控制器操作将是:

Then your controller action would be:

public ActionResult ChartList() 
{
   var model = new ChartAndListViewModel();
   model.ChartItems = _db.getChartItems();
   model.ListItems = _db.getListItems();

   return View(model);
}

最后你的观点是:

@model Application.ViewModels.ChartAndListViewModel

<h2>Blah</h2>

@Html.RenderPartial("ChartPartialName", model.ChartItems);

@Html.RenderPartial("ListPartialName", model.ListItems);
