Question

在按钮上单击我调用了一个js函数，该函数调用为action方法。但如果json结果为0（不是错误），我想重定向到局部视图。 JS功能：

function AssignButtonClicked(step, parent, show) {
    alert("coming: " + step + " parent: " + parent + " show is : " + show);

    $.ajax({

        type: "POST",

        url: "/Jobs/PassInstructionTest",

        data: "{stepGuid: '" + step + "', parentGuid: '" + parent + "'}",

        contentType: "application/json; charset=utf-8",

        dataType: "json",

        success: function (response) {

            alert("resp is : " + response);
            if (response == '0') {
                alert('qa called!');
                $("#forqa").show();                   
            }
            if (response == '1') {

            }
        },

        error: function (response) {
            alert(response.responseText + " error for fail");
        },

    });
    return false;
}

控制器中的操作方法：

public ActionResult PassInstructionTest(Guid stepGuid, Guid parentGuid, string show)
{
  bool isQA = false;
  if (!isQA)
  {
    return Json(0, JsonRequestBehavior.AllowGet);
  }
  else
  {
    return PartialView("MyPartialView");
  }
}

当调用MyPartialView时，它会抛出错误，因为执行子请求时出错。

请提供解决方案。

将Html转换为字符串然后将其作为json传递。

public virtual string RenderPartialViewToString(string viewName, object model)
    {
        //Original source code: http://craftycodeblog.com/2010/05/15/asp-net-mvc-render-partial-view-to-string/
        if (string.IsNullOrEmpty(viewName))
            viewName = this.ControllerContext.RouteData.GetRequiredString("action");

        this.ViewData.Model = model;

        using (var sw = new StringWriter())
        {
            ViewEngineResult viewResult = System.Web.Mvc.ViewEngines.Engines.FindPartialView(this.ControllerContext, viewName);


            var viewContext = new ViewContext(this.ControllerContext, viewResult.View, this.ViewData, this.TempData, sw);
            viewResult.View.Render(viewContext, sw);

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



  public ActionResult PassInstructionTest(Guid stepGuid, Guid parentGuid,string show)
  {
   bool isQA = false;
   if (!isQA)
   {
      return Json(0, JsonRequestBehavior.AllowGet);
   }
   else
   {
       return update_section = new
            {
          ShippingMethodUpdateHtml =   this.RenderPartialViewToString("MyPartialView", null)
            },
   }
  }

从ajax调用返回局部视图
