服务端代码：
using System;using System.Collections.Generic;using System.Linq;using System.IO; using System.Net;using System.Web;using System.Web.Services;namespace JQueryUploadDemo{ /// <summary> /// $codebehindclassname$ 的摘要说明 /// </summary> [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] 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(uploadPath file.FileName); //下面这句代码缺少的话，上传成功后上传队列的显示不会自动消失 context.Response.Write("1"); } else { context.Response.Write("0"); } } public bool IsReusable { get { return false; } } }}
