uploadify文件批量上传

uploadify能够时间文件的批量上传，JS文件包下载地址，使用说明可以参考官网文档（http://www.uploadify.com/documentation/）

使用方法如下代码：

$("#btnfileupload").uploadify({
                swf: '/Content/uploadify/uploadify.swf',
                cancelImg: '/Content/uploadify/cancel.png',
                uploader: '../upload/Uploadfile',
                width: ,
                buttonText: '批量上传',
                fileTypeExts: '*.jpg;*.gif;*.jpeg;*.png;',
                formData: { 'filepath': 'ttrs' },
                fileObjName: 'upimage',
                auto: true,
                multi: true,
                uploadLimit: ,
                successTimeout: ,
                removeCompleted: true,
                removeTimeout: ,
                onUploadSuccess: function (file, data, response) {
                    $("#mydefault").hide();
                    data = window.eval('(' + data + ')');//转换成JSON
                    file.name = data.piccode;
                    if ($("#" + data.piccode).length == )
                        jQuery("<li id=\"" + data.piccode + "\"><img src='" + data.picurl + "' /><input type=\"hidden\" name=\"detailpic\" value=\"" + data.piccode + "\"></li>").appendTo("#mypicshowdiv");
                }
            });

后台MVC4代码如下：

        [HttpPost]
        public JsonResult UploadImg(HttpPostedFileBase upimage)
        {
            string pic = "", error = "",pcode="";
            try
            {
                if (upimage != null)
                {
                    string fileName = DateTime.Now.ToString("yyyyMMdd") + System.IO.Path.GetFileName(upimage.FileName);
                    string[] pictext = { ".jpg",".gif",".bmp",".png",".jpeg" };
                    string extenname= System.IO.Path.GetExtension(fileName);
                    if (pictext.Contains(extenname))
                    {
                        string filePhysicalPath = Server.MapPath("~/Upload/Images/" + fileName);
                            upimage.SaveAs(filePhysicalPath);
                            pic = "/Upload/Images/" + fileName;
                        }
                        else
                        {
                            error = "";
                            pic =pic ;
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                error = ex.Message;
            }
            return Json(new
            {
                errorcode = error,
                picurl = pic,
                piccode = pcode
            });
        }
