Something like what you're trying to do is only possible with the HTML5 file api(which allows reading files). I've never had to do something like this before, but I suggest:

//file is ready for sending
var file = fileInput.files[0];
var fReader = new FileReader();

fReader.onloadend = function(){
  var xhr = new XMLHttpRequest();
  //processing and send 
  this.result;
};

fReader.readAsDataURL(file);
