嗨我正在使用一个应该允许选择多个fileupload的代码，当上传文件时，它应该显示一个带有加载百分比的进度条
这是我的代码
Webform.aspx

},
/* progress bar call back*/
uploadProgress: function (event, position, total, percentComplete) {
var pVel = percentComplete + '%';
progressbarDiv.width(pVel);
progressbarLabel.html(pVel);
},
success: function () {
progressbarLabel.text('Terminé');
progressbarDiv.fadeOut(2000);

UploadHandler.ashx
public class UploadHandler : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
if (context.Request.Files.Count > 0)
{
HttpFileCollection files = context.Request.Files;
for (int i = 0; i < files.Count; i++)
{
System.Threading.Thread.Sleep(1000);
HttpPostedFile file = files[i];
string fileName = context.Server.MapPath("~/Uploads/" + System.IO.Path.GetFileName( file.FileName));
file.SaveAs(fileName);
}
}
}
public bool IsReusable
{
get
{
return false;
}
}
}
它不起作用，进度条没有出现，文件没有存储在Uploads目录
