Jquery.Uploadify v3.2 使用经验

最近项目要用到多文件上传，HTML里没有这个功能，然后上网找到了Uploadify，一个非常不错的JQuery上传插件。然后上网找到了个uploadify-v2.1.0版的例子，写得很好，可是Uploadify v3.2版本有很多方法不一样了。只好硬着头皮去官方网看鸡肠文档,其中还发现官方网下载下来的文件，有个图片的位置放错地方了，要自己手动调一下。我还在网上抄了人家的个asp.net的Demo，来跟大家分享一下。

        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");
            }  

        }

本人太懒了，以上代码纯属Copy
