我正在使用带有 jquery 客户端脚本的 MVC 4 和 Backload 文件上传器。我使用 nuget 获取了 Demo 包，该包下载了控制器并作为起点查看。
我的问题在我的本地服务器和在线服务器上，在我上传文件后，应用程序无法准确显示所有上传的文件。通常它会卡住只显示 4 或 5 个文件而忽略其余文件。即使我删除其中一个正在显示的文件并刷新页面，它仍然显示相同的 4 或 5 张图像。我已验证应用程序正在上传和/或删除文件。我尝试通过按 cntl F5 清除缓存，但无济于事。
谁能指出我正确的方向来纠正这个问题。下面是来自从 NuGet 下载的演示的视图和控制器。
控制器：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace Spotless_Interiors.Controllers
{
[Authorize]
public class BackloadDemoController : Controller
{
public ActionResult Index()
{
return View();
}
}
}
看法：
@{
ViewBag.Title = "File Upload";
}
