进度条虽帅,我只取一瓢饮
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
{
    //----------------------------------------------------------------
    /// <summary>
    
/// Import画面用
    
/// </summary>
    //----------------------------------------------------------------
    public class tmp_UploadFile
    {
        /// <summary></summary>
        public HttpPostedFileBase FileName { getset; }
    }
}

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
//----------------------------------------------------------------
        /// <summary>
        
/// アップロード
        
/// </summary>
        
/// <returns></returns>
        //----------------------------------------------------------------
        [HttpPost]
        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
<table align="center" style="margin-bottom:200px">
    <tr>
        <td>
            <div style="width:470px">
                <input type="text" id="tbx-file-path" value="ファイルを選択してください" readonly="readonly" />
            </div>
        </td>
        <td>
            <div style="width: 60px">
                <span class="btn btn-primary fileinput-button">
                    <span>選 択</span>
                    @Html.TextBoxFor(m => m.FileName, new { id = "file-upload", type = "file", accept = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel" })
                </span>
            </div>
        </td>
        <td>
            <div style="width:60px">
                <class="btn btn-primary" href="#" id="hl-start-upload">アップロード</a>
            </div>
        </td>
    </tr>
</table>

<div id="loadingOver" class="loadingOver"></div>
<div id="dvloader" class="dvloader">
    <span class="label label-info" style="align-content:center"> 処理中、少々お待ちください</span><br />
    <br />
    <img id="loadingGif" src="../Content/img/loader.gif" alt="" />
</div>

@section scripts{
    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/jqueryui")
    @Scripts.Render("~/bundles/jqueryval")
    @Scripts.Render("~/bundles/common")
    @Scripts.Render("~/bundles/fileupload")
    <script type="text/javascript">
        
var data_upload;
        $(document).ready(
function () {
            'use strict';
            $('#file
-upload').fileupload({
                url: '..
/Bihin/UploadFile',
                dataType: 'json',
                add: 
function (e, data) {
                    data_upload 
= data;
                },
                done: 
function (event, data) {
                    
if (data.result.isUploaded) {
                        $(
"#tbx-file-path").val("ファイルを選択してください");
                        data_upload 
= "";
                    }

                    $(
"#dvloader").css("display""none");
                    $(
"#loadingOver").css("display""none");

                    alert(data.result.message);
                },
                fail: 
function (event, data) {
                    data_upload 
= "";
                    
if (data.files[0].error) {

                        $(
"#dvloader").css("display""none");
                        $(
"#loadingOver").css("display""none");

                        alert(data.files[
0].error);
                    }
                }
            });
        });

        $(
"#hl-start-upload").on('click', function () {
            
if (data_upload) {
                $(
"#dvloader").css("display""block");
                $(
"#loadingOver").css("display""block");
                data_upload.submit();
            }
            
return false;
        });

        $(
"#file-upload").on('change', function () {
            $(
"#tbx-file-path").val(this.files[0].name);
        });

        
</script>
}

√,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
有点长啊,还好,并不忧伤
就酱。
