Detailed explanation of the use of JQuery.uploadify upload file plug-in for ASP.NET_jquery

Later, a friend recommended an upload plug-in called uploadify. It seemed to be very good, so I downloaded a sample from the official website and ran it. It felt very good. I just beautified it a little and it was OK...!

Let’s talk about the usage process:

1. Download

Official website: http://www.uploadify.com/

Direct download: jquery.uploadify-v2.1.0.rar

My Demo: MyUpload.rar The official website also has a demo

After downloading and unzipping:

 

Note: It contains demo but it is for PHP, and there is also a help document: uploadify v2.1.0 Manual.pdf.

2. Create project:

The structure is as shown in the figure>>

File description:

All files in the A.js folder: required, unzip and copy them from the downloaded package, you can change the name yourself

B.Default.aspx: Test page, no code in the background

Copy code The code is as follows:

<%@ Page Language="C#" AutoEventWireup="true" Codebehind="Default.aspx.cs" Inherits="WebApplication2._Default" %>

Upload| Cancel upload

C.Upload.aspx: Process uploaded files

Copy code The code is as follows:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Upload.aspx.cs" Inherits="WebApplication2. Upload" %>

Code

Copy code The code is as follows:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.IO;
namespace WebApplication2
{
public partial class Upload : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
HttpPostedFile file = Request.Files["FileData"];
string uploadpath = Server.MapPath(Request["folder"] "\");
if (file != null)
{
if (!Directory.Exists(uploadpath))
{
Directory.CreateDirectory(uploadpath);
}
file.SaveAs(uploadpath file.FileName);
Response.Write("1");
}
else
{
Response.Write("0");
}
}
}
}

D.upload这个文件加也是必需
3.运行结果：

  

4.最后说说：这个只是一个简单的入门例子，至于界面可以根据自己的需要去改
