ASP.NET MVC - 结合JSON结果用的ViewResult [英] ASP.NET MVC - Combine Json result with ViewResult

问题描述

我可以返回也包含了渲染视图一个JSON结果？

Can I return a Json result that contains also a rendered view?

我需要它与它的HTML和其他一些属性一起返回提交表单的新ID。

I need it to return the new ID of a submitted form along with its HTML and some other properties.

也是可以帮助时，我需要返回一个JSON对象中从一个操作两个（或更多）查看结果。

Also that can be helpful when I need to return two (or more) view results from one action inside a Json object.

谢谢！

推荐答案

您也可以呈现PartialViewResult为一个字符串，然后通过JSON传递这个字符串你的看法，使用jQuery在你的页面渲染它。

You can also render a PartialViewResult to a string, and then pass this string via JSON to your view, rendering it in your page using jQuery.

您可以看到，在这个帖子：<一href=\"http://www.atlanticbt.com/blog/asp-net-mvc-using-ajax-json-and-partialviews/\">http://www.atlanticbt.com/blog/asp-net-mvc-using-ajax-json-and-partialviews/.

我创建了一个扩展，使其更容易：

I've created an extension to make it easier:

public static class MvcHelpers
{
    public static string RenderPartialView(this Controller controller, string viewName, object model)
    {
        if (string.IsNullOrEmpty(viewName))
            viewName = controller.ControllerContext.RouteData.GetRequiredString("action");

        controller.ViewData.Model = model;
        using (var sw = new StringWriter())
        {
            ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(controller.ControllerContext, viewName);
            var viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, sw);
            viewResult.View.Render(viewContext, sw);

            return sw.GetStringBuilder().ToString();
        }
    }
}

在我的控制器我叫它如下：

In my controller I call it as follows:

const string msg = "Item succesfully updated!";
return new JsonResult
           {
               Data = new
                          {
                              success = true, 
                              message = msg,
                              view = this.RenderPartialView("ProductItemForm", model)
                          },
               JsonRequestBehavior = JsonRequestBehavior.AllowGet
           };

在哪里这的情况下，控制器，ProductItemForm是我的看法和模式是我productItem对象：）

Where "this" is the controller in the case, "ProductItemForm" is my view and "model" is my productItem object :)
