3.2 Version Uploadify detailed examples (including FF and IE session issues)

Recently do the project encountered upload need to show the progress of the problem, through the uploadfiy very good to solve the problem but (IE9 there is a button can not click the problem, still can't find the good plan)

You need to download jquery.tmpl.min.js and reference under jquery when using the uploadfiy3.2 version

 $ ("#uploadify"). Uploadify ({' Uploader ': '/lzks/handler/bigfileuploadhandler.ashx ', ' swf ': '                /lzks/scripts/uploadify/uploadify.swf ', ' cancelimage ': '/lzks/scripts/uploadify/cancel.png ', ' Queueid ': ' Filequeue ',//' auto ': false, ' multi ': true, ' buttontext ': ' File Upload '                    , ' FormData ': {' aspsessid ': aspsessid, ' AUTHID ': auth}, ' OnSelect ': function (file) {                    $ (' #uploadify '). Uploadifysettings (' FormData ', {' Aspsessid ': aspsessid, ' AUTHID ': auth});                alert (formdate); }, ' OnComplete ': function (file, data, response) {}, ' Onqueuecomplete ': func tion () {alert ("Upload complete!)                    ");                $ (' #fileQueue '). attr (' style ', ' Visibility:hidden '); }, ' Onselecterror ': function (file, ErrorCode, errormsg) {$ (' #fileQueue '). attr (' style ', ' Visibility:hidden '); }, ' Onuploadstart ': function (file) {$ (' #fileQueue '). attr (' style ', ' top:200px;left:400p                X;width:400px;height:400px;visibility:visible ');        }            }); });

Upload with Uplodify There is also a small problem is that in the FF session will be lost, add the following code in the Gobal to the upload process defined session to the server

 protected void Application_BeginRequest (object sender, EventArgs e) {/* We guess at the this point session                Already retrieved by application so we recreate cookies with the session ID ... */try {                String session_param_name = "Aspsessid";                String session_cookie_name = "Asp.net_sessionid"; if (httpcontext.current.request.form[session_param_name]! = null) {Updatecookie (session                _cookie_name, Httpcontext.current.request.form[session_param_name]);                    } else if (httpcontext.current.request.querystring[session_param_name]! = null) {                Updatecookie (Session_cookie_name, Httpcontext.current.request.querystring[session_param_name]); }} catch {} try {string Auth_param_nam                E = "AUTHID"; String auth_cookie_name =Formsauthentication.formscookiename; if (httpcontext.current.request.form[auth_param_name]! = null) {Updatecookie (Auth_cooki                E_name, Httpcontext.current.request.form[auth_param_name]);                    } else if (httpcontext.current.request.querystring[auth_param_name]! = null) {                Updatecookie (Auth_cookie_name, Httpcontext.current.request.querystring[auth_param_name]); }} catch {}} private void Updatecookie (string cookie_name, St            Ring cookie_value) {HttpCookie cookie = HttpContext.Current.Request.Cookies.Get (cookie_name);            if (null = = cookie) {cookie = new HttpCookie (cookie_name); } cookie.            Value = Cookie_value;        HttpContext.Current.Request.Cookies.Set (cookie); }

Define the following two variables before JS loading

var auth = "<% = request.cookies[formsauthentication.formscookiename]==null?" String. Empty:request.cookies[formsauthentication.formscookiename]. Value%> "; var aspsessid = "<%= session.sessionid%>";

The handler file code is as follows: public class Bigfileuploadhandler:ihttphandler, irequiressessionstate {dalfile fdal = new DAL        File (); public void ProcessRequest (HttpContext context) {context.            Response.ContentType = "Text/plain"; Videoupload (context, Clsoft.        Web.LZKS.Edu.Globe.filename); } public void Videoupload (HttpContext context, string filefoldername) {context.            Response.Charset = "Utf-8"; String Aaaaaaa=context.            request.querystring["SessionID"]; Httppostedfile file = context.            request.files["Filedata"];            String uploadpath = HttpContext.Current.Server.MapPath (Uploadfilecommon.createdir (filefoldername)); if (file! = null) {if (!                Directory.Exists (Uploadpath)) {directory.createdirectory (Uploadpath);                } model.modelfile Model = new Model.modelfile (); Model. file_id = Guid.NewGuid (). ToString (); Model. file_name = file.                FileName; Model.                File_path = Uploadfilecommon.createdir (filefoldername); Model. file_size = file.                ContentLength; Model. file_extension = file. Filename.substring (file.                Filename.lastindexof ('. ') + 1); Model.                File_date = DateTime.Now; Model. File_currentman = Clsoft.                Web.LZKS.Edu.Globe.name; File. SaveAs (Uploadpath + model.                            file_name);                list<model.modelfile> list = null; if (context.                session["File"] = = null) {list = new list<model.modelfile> (); } else {list = context.                session["File"] as list<model.modelfile>; } list.                ADD (model); Context.            Session.add ("File", list); } else {context.            Response.Write ("0");      }   }//The function of this code is to save the information of multiple files to the context.  session["File"] as list<model.modelfilemodel.modelfile> for file information class
Implement bulk upload of information to session
