How to get the filename from the Javascript FileReader?

This is prob not the best solution, BUT it worked for me.

var reader = new FileReader();
reader.fileName = file.name // file came from a input file element. file = el.files[0];
reader.onload = function(readerEvt) {
    console.log(readerEvt.target.fileName);
};

Not the best answer, but a working one.
