使用引导进度条以模态显示上传进度

【中文标题】使用引导进度条以模态显示上传进度【英文标题】：Display Upload Progress in Modal with Bootstrap Progress Bar 【发布时间】：2015-04-20 03:01:02 【问题描述】：我正在构建一个 c# MVC 应用程序，它显示一个表单并允许用户上传一些文件。当用户点击提交时，会出现一个带有进度条的模式，设置为 100% 并显示一条消息“请稍候，等等。”
我希望能够捕获上传过程的进度并将其显示在模态的进度条中。
所以经过一些 Google 搜索后，我想出了this solution，但我不确定如何使其适应我目前的情况。
这是我的代码：
索引.cshtml
<h4>Please fill out the form below and select at least one file to upload.</h4>
@using (Html.BeginForm("Index", "Home", FormMethod.Post, new enctype = "multipart/form-data", id = "upldFrm" ))
<div class="row">
<div class="col-md-2">
<h5>Your Name:</h5>
</div>
<div class="col-md-4">
<input type="text" name="uname" class="form-control" required placeholder="John Smith">
</div>
</div>
<div class="row">
<div class="col-md-2">
<h5>Your Email:</h5>
</div>
<div class="col-md-4">
<input type="email" name="email" class="form-control" required placeholder="test@test.com">
</div>
</div>
<div class="row">
<div class="col-md-2">
<h5>Your Company:</h5>
</div>
<div class="col-md-4">
<input type="text" name="company" class="form-control" required placeholder="Test Company, Inc">
</div>
</div>
<div class="row">
<div class="col-md-2">
<h5>Choose file(s) to upload (Max 500MB):</h5>
</div>
<div class="col-md-4">
<input name="files" type="file" id="files" multiple="multiple" class="form-control" required />
</div>
</div>
<div class="row">
<div class="col-md-2">
<h5></h5>
</div>
<div class="col-md-4">
<input id="sbmtBtn" type="submit" name="submit" value="Upload" class="btn btn-primary" data-toggle="modal" data-target="#myModal" />
</div>
</div>
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" data-backdrop="static">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h1>Uploading...</h1>
</div>
<div class="modal-body">
Please wait while we are uploading your files
<div class="progress">
<div class="progress-bar progress-bar-striped active" role="progressbar" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100" style="width: 100%">
</div>
</div>
</div>
</div>
</div>
</div>
<script>
$('sbmtBtn').on('click', function ()
$('#upldFrm').submit();
);
</script>
这是我的控制器
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Net.Mail;
namespace vidup.Controllers
public class HomeController : Controller
public ActionResult Index()
return View();
[HttpPost]
public ActionResult Index(List<HttpPostedFileBase> files)
var userName = Request["uname"].ToString();
var userEmail = Request["email"].ToString();
var userCompany = Request["company"].ToString();
ViewBag.Username = userName;
ViewBag.UserCompany = userCompany;
ViewBag.UserEmail = userEmail;
int i = 0;
var path = Path.Combine(Server.MapPath("~/Uploads"), userCompany, userName, DateTime.Now.ToString("MM-dd-yyyy h-mm-tt"));
if (!Directory.Exists(path))
DirectoryInfo di = Directory.CreateDirectory(path);
foreach (HttpPostedFileBase item in files)
i++;
if (item != null && item.ContentLength > 0)
var fileName = Path.GetFileName(item.FileName);
var fullPath = Path.Combine(path, fileName);
ViewBag.Message3 = fileName;
ViewBag.Message4 = fullPath;
try
item.SaveAs(fullPath);
var fileCount = i + " File(s) uploaded successfully";
ViewBag.Message = fileCount;
catch (Exception e)
ViewBag.Message = e;
else
ViewBag.Message = "No File selected";
return View("Status");
public ActionResult Status()
return View();
编辑：
我尝试在我提供的帖子中添加代码，但出现错误
Uncaught ReferenceError: formdata is not defined
这就是我现在的视图，谁能指导我为什么会出现这个错误？或者如何解决？
<div class="row">
<div class="col-md-2">

</div>
</div>
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" data-backdrop="static">
<div class="modal-dialog">

</div>
</div>
<script>
function submitForm()
$('#myModal').modal('show');
var file=document.getElementById('files').files[0];
var formData = new FormData();
formdata.append("file_name", file);
ajax = new XMLHttpRequest();
ajax.upload.addEventListener("progress", progressHandler, false);
ajax.addEventListener("load", completeHandler, false);
ajax.open("POST", '@Url.Action("Index","Home")', true)
ajax.send(formdata);
function progressHandler(event)
var percent = (event.loaded / event.total) * 100;
$('.bar').width(percent);
function completeHandler()
$('#myModal').modal('hide');
$('.bar').width(100);
//$('sbmtBtn').on('click', function ()
//
// $('#upldFrm').submit();
//);
</script>
【问题讨论】：
有人可以帮忙吗？或指出我正确的方向？ 这是有争议的事情，但进度条实际上只是为了向用户显示 IMO 正在发生的事情。许多人已经不再使用实际进度，而只是显示“加载轮”或类似的东西。有一个准确的进度条和附加值很少。 【参考方案1】：我使用以下代码来获取进度条，并且仍然让控制器完成上传文件的工作。
在头部我包含了这些脚本
<script src="~/Scripts/jquery-2.1.3.js"></script>
<script src="http://malsup.github.com/jquery.form.js"></script>
<script src="~/Scripts/bootstrap.js"></script>
<script src="~/Scripts/modernizr-2.8.3.js"></script>
<link href="~/Content/Site.css" rel="stylesheet" type="text/css" />
<link href="~/Content/bootstrap.css" rel="stylesheet" type="text/css" />
然后是表单的正文和脚本。
@using (Ajax.BeginForm("Index", "Home", new AjaxOptions() HttpMethod = "POST" , new enctype = "multipart/form-data" ))
<div class="row">
<div class="col-md-2">
<h5>Your Name:</h5>
</div>
<div class="col-md-4">
<input type="text" name="uname" class="form-control" required placeholder="John Smith">
</div>
</div>
<div class="row">
<div class="col-md-2">
<h5>Your Email:</h5>
</div>
<div class="col-md-4">

</div>
</div>
<br />
<div class="progress">
<div class="progress-bar">0%</div>
</div>
<div id="status"></div>
<script>
(function ()
var bar = $('.progress-bar');
var percent = $('.progress-bar');
var status = $('#status');
$('form').ajaxForm(
beforeSend: function ()
status.empty();
status.html("Please Wait While We Upload Your File(s)");
var percentValue = '0%';
bar.width(percentValue);
percent.html(percentValue);
,
uploadProgress: function (event, position, total, percentComplete)
var percentValue = percentComplete + '%';
bar.width(percentValue);
percent.html(percentValue);
,
success: function (d)
var percentValue = '100%';
bar.width(percentValue);
percent.html(percentValue);
$('#fu1').val('');
status.empty();
alert(d);
,
complete: function (xhr)
status.html("You can Upload again or close this page.");
);
)();
