javascript - cannot upload files and vars with xhr2 and web workers -

-

i try create code upload files using xhr2 , web workers. thought should use web workers , if file big, web page not freeze.

this not working 2 reasons, never used web workers before, , want post server file , vars @ same time, same xhr. when vars mean name of file, , int.

heres got

client side

//create worker var worker = new worker('fileupload.js');  worker.onmessage = function(e) {  alert('worker says   '+e.data); }  //handle workers error worker.onerror =werror; function werror(e) {   console.log('error: line ', e.lineno, ' in ', e.filename, ': ', e.message);  }  //send stuff worker  worker.postmessage({  'files' : files, //img or video  'name' : nameofthepic, //text  'id':imageinsertid //number  });

inside worker (fileupload.js file)

onmessage = function (e) {var name=e.data.name; var id=e.data.id ; var file=e.data.files;  //create var catch anser of server var datax;        var xhr = new xmlhttprequest();                xhr.onload = function() {                  if (xhr.status == 200) {datax=xhr.response;}                    else { datax=525;}//actually, whatever, give value         };       xhr.open('post', 'upload.php');                                           xhr.send(file,name,id);           //i tried xhr.send('file=file&name=name&id=id');  , still nothing           //i tried  text/int xhr.send('name=name&id=id'); , still nothing

i confused. cannot send server. no feedback worker. dont know if data send fileupload.js. server side not insert.

is possible, sending files , text @ same time? missing?

i need pass text , int along file, server side not upload file, insert database int , text, if file uploaded succesfully. easy formdata , xhr, but, putting web workers in middle, cant right.

also, can use transferable objects speed things up? transferable objects supported in major browsers?

thanks in advance
