概述

复制代码代码如下:

        $(document).ready(function () {
            $("#uploadify").uploadify({
                'uploader': 'js/jquery.uploadify-v2.1.4/uploadify.swf', //uploadify.swf文件的路径

                },
                'onComplete': function (event, ID, fileObj, response, data) { //每完成一次文件上传时触发一次
                    alert('There are ' + data.fileCount + ' files remaining in the queue.');
                },
                'onAllComplete': function (event, data) { //当上传队列中的所有文件都完成上传时触发
                    alert(data.filesUploaded + ' files uploaded successfully!');
                }
            });
        });
    </script>
</head>
<body>
    <form id="form1" runat="server">

    </div>

复制代码代码如下:

<%@ WebHandler Language="C#" Class="UploadHandler" %>

using System;

        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;
        }
    }
}
