C# 使用引导进度条在模式中显示上载进度
我正在构建一个c#MVC应用程序,它提供一个表单并允许用户上传一些文件。当用户单击submit(提交)时,将显示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modal的进度栏中 所以,在谷歌搜索了一段时间后,我想出了一个办法,但我不确定如何适应我目前的情况 这是我的密码: Index.cshtmlC# 使用引导进度条在模式中显示上载进度,c#,jquery,asp.net-mvc,twitter-bootstrap,C#,Jquery,Asp.net Mvc,Twitter Bootstrap,我正在构建一个c#MVC应用程序,它提供一个表单并允许用户上传一些文件。当用户单击submit(提交)时,将显示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modal的进度栏中 所以,在谷歌搜索了一段时间后,我想出了一个办法,但我不确定如何适应我目前的情况 这是我的密码: Index.cshtml <h4>Please fill out the form below and select at least one f

上传。。。

我使用以下代码获取进度条,但仍让控制器完成上传文件的工作
在我的头脑中包括了这些脚本
<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" />
然后是表单的主体和脚本

有人能帮忙吗?或者给我指出正确的方向?这是一个值得讨论的问题,但进度条实际上只是向用户显示正在发生的事情。许多人已经不再使用实际进度,而只是显示“加载轮”或类似的内容。有一个准确的进度条需要很多开销,附加值很少。我喜欢格雷哈默先生
