Question

I m New to MVC, and I m implementing a web app with Much of AJAX and part perspectives.

我有2个观点:1个基本观点和1个部分观点。每个观点都有自己的控制者。基本观点通过模型向部分观点发送数据。

我想让部分观点/控制者向基调/控制员发送数据。这样做的最佳方式是什么? 是否有办法从部分观点行动中恢复基本观点?

        public ActionResult SendDataToBaseView()
        {
            return View("BaseView", viewModel);
        }

Answer 1

It s not quite clear what your setup is.

If you re updating HTML that was rendered from the main view, then you ll likely have another controller action on the same controller on which you called an action to render the base view. This other controller action may return JSON or HTML (as a Partial View perhaps) and it will be your responsibility on the client side to take the result of the AJAX call and populate the sections of the page that were rendered by the base view with this new data.

在这方面,我想采取的步骤正在采取。

Controller action called to render base view. Let s call the controller BaseController and the action Index
Inside the base view a call is made to render a partiaol view, via Html.RenderPartial(), Html.RenderAction() or Html.Action()
Response is sent to client
Event happens on client requiring update to data rendered by base view.
AJAX request is made to BaseController Update action that returns a JsonResult containing data that can be used to updates parts of the response outputted by the base view.
Receive response on client side and update those parts of the DOM.
