jquery uploadify插件实现上传文件进度条效果
时间：2022-06-25 17:45:25 编辑：袖梨 来源：一聚教程网
一、jquery进度条代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="UpLoad.aspx.cs" Inherits="UploadifyDemo_UpLoad" %>
css" rel="stylesheet" type="text/css" />
二、后端程序代码，产生jquery进度条的数据源：
<%@ WebHandler Language="C#" Class="UploadHandler" %>
using System;
using System.Web;
using System.IO;
public class UploadHandler : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
context.Response.Charset = "utf-8";
HttpPostedFile file = context.Request.Files["Filedata"];
string uploadPath = HttpContext.Current.Server.MapPath(@context.Request["folder"]);
if (file != null)
{
if (!Directory.Exists(uploadPath))
{
Directory.CreateDirectory(uploadPath);
}
file.SaveAs(Path.Combine(uploadPath, file.FileName));
context.Response.Write("1");
}
else
{
context.Response.Write("0");
}
}
public bool IsReusable
{
get
{
return false;
}
}
}
