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

            });

        }
