javascript - how to read audio file in fire fox using file reader class - 


savebutton.onclick = function(e) {    var filename= file.name;    console.warn("file name " +filename);  //alert("hello");   var audiotype = "audio/*";   //console.warn("audiotype " +audiotype);       if(filename.type.match(audiotype))       {       console.warn("audiotype " +audiotype);       var reader=new filereader();       console.warn("file reader object " +reader);       read.onload=function(e)      {      var rowdata=reader.result;      console.warn("file reader object row data " +rowdata);      }        reader.readasbinarystring(filename);     }          }

here on save button event getting audio file name using file.name.now want read in buffer because want upload file on server.so want read using file reader class.but here not getting output.can 1 plzz me figure out problem in code.

very broad solution, supposing using post request upload file , server accepting post request.

var myfile; var myform = new formdata(); myform.append('nameofthefile', myfile, 'nameofthefilewithextension'); var xhr = new xmlhttprequest(); xhr.open('post', 'http://foo.com/submitform.php'); xhr.send(myform);

brief explanation; have file object called myfile , want upload server, need make request xmlhttprequest , append formdata field it. easier way using formdata object, append file , send formdata xmlhttprequest.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
