道理相通,我简单分享下在.net MVC下的实装。

1.制作Model类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
 
namespace RCRS.WebApp.LG.EM.Models
{
  //----------------------------------------------------------------
  /// 
  /// Import画面用
  /// 
  //----------------------------------------------------------------
  public class tmp_UploadFile
  {
    /// 
    public HttpPostedFileBase FileName { get; set; }
  }
}

2.实装controller里的对应方法,我这个处理逻辑比较复杂,懒得修改了,反正就这个意思

    public virtual ActionResult UploadFile()
    {
      HttpPostedFileBase uploadedFile = Request.Files["FileName"];
      string message = "アップロード失敗しました。";
      bool isUploaded = false;
      string path = "";
      string dateTimeNow = DateTime.Now.ToString("yyMMdd-hhmmss");
      string userName = User.Identity.GetUserName();
      string uploadMsg = string.Empty;
 
      if (uploadedFile != null && uploadedFile.ContentLength != 0)
      {
        string pathForSaving = Server.MapPath("~/App_Data/Uploaded/");
        try
        {
          if (BsnssBihin.IsExcel(uploadedFile.FileName))
          {
            path = System.IO.Path.Combine(pathForSaving, dateTimeNow + "_" + uploadedFile.FileName);
            uploadedFile.SaveAs(path);
            isUploaded = BsnssBihin.UploadBihinChange(path, userName, ref uploadMsg);
            if (isUploaded)
            {
              message = "アップロード成功しました!" + "\n" + uploadMsg;
              Logger.Info("[成功]備品アップロード, " + dateTimeNow + ", " + "[" + userName + "]" + "[" + path + "]" + uploadMsg);
            }
            else
            {
              message = "アップロード失敗しました。" + "\n" + uploadMsg;
              Logger.Info("[失敗]備品アップロード, " + dateTimeNow + ", " + "[" + userName + "]" + "["+path + "]" + uploadMsg);
            }
          }
          else
          {
            message = "ファイルの形式は不正です。";
          }
        }
        catch (Exception ex)
        {
          message = string.Format("失敗しました: {0}", ex.Message);
          Logger.Info("[失敗]備品アップロード: " + ex.Message + dateTimeNow + ", " + "[" + userName + "]" + "[" + path + "]");
        }
      }
      return Json(new { isUploaded = isUploaded, message = message }, "text/html");
    }

3.页面的实装

@model RCRS.WebApp.LG.EM.Models.tmp_UploadFile
選 択 @Html.TextBoxFor(m => m.FileName, new { id = "file-upload", type = "file", accept = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel" })
処理中、少々お待ちください

JQuery fileupload插件实现文件上传功能
@section scripts{ @Scripts.Render("~/bundles/jquery") @Scripts.Render("~/bundles/jqueryui") @Scripts.Render("~/bundles/jqueryval") @Scripts.Render("~/bundles/common") @Scripts.Render("~/bundles/fileupload") }

就是这个样子

还附赠了一个简易loding的实现

贴出CSS代码:

.dvloader {
  display:none;
  position:absolute;
  top:40%;
  left:40%;
  width:20%;
  height:20%;
  z-index:1001;
  text-align:center;
  font-size:1.5em;
}
 
.loadingOver {
  display:none;
  position:absolute;
  top:0;
  left:0;
  width:100%;
  height:100%;
  background-color:#f5f5f5;
  opacity:0.5;
  z-index:1000;
}

这里,多说一嘴:
关于input 的accept属性,这里只想读入Excel,所以
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel
