Fileupload using Filereader in chrome - html

Question

I have to upload a file from the local memory of application (HTML5 File api). Onselect, the user should be able to upload directly without any question. The idea is to manage download/upload seamless to the user. Here is the code :
$("body").on("click", ".upload-file", function(e){
var fileToUpload = $('input:radio[name=optionsRadios]:checked').val();
var formData = new FormData();
$('input:radio[name=optionsRadios]:checked').parent().parent().parent().remove();
window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
window.requestFileSystem(window.TEMPORARY, 50*1024*1024, initFS, errorHandler);
var reader = new FileReader();
function initFS(fs){
fs.root.getDirectory('/', {}, function(dirEntry){
var dirReader = dirEntry.createReader();
dirReader.readEntries(function(entries) {
for(var key = 0; key < entries.length; key++) {
var entry = entries[key];
if (entry.isFile){
var name = entry.name;
if(name == fileToUpload){
getAsText(entry.toURL());
formData.append('file', entry.toURL);
break;
}
}
}
}, errorHandler);
}, errorHandler);
}
function errorHandler(){
console.log('An error occured');
}
function getAsText(readFile) {
alert ("getting as text :" +readFile);
var reader = new FileReader();
// Read file into memory as UTF-16
reader.readAsText(readFile, "UTF-16");
// Handle progress, success, and errors
reader.onprogress = updateProgress;
reader.onload = loaded;
reader.onerror = errorHandler;
}
function loaded(evt) {
// Obtain the read file data
alert("loaded file");
var fileString = evt.target.result;
// Handle UTF-16 file dump
if(utils.regexp.isChinese(fileString)) {
//Chinese Characters + Name validation
}
else {
// run other charset test
}
// xhr.send(fileString)
}
var serverurl = "/fileserver/uploadFile?selpath="+fileToUpload;
var xhr = new XMLHttpRequest();
xhr.open('POST', serverurl);
xhr.onload = function () {
if (xhr.status === 200) {
console.log('all done: ' + xhr.status);
} else {
console.log('Something went terribly wrong...');
}
};
xhr.send(formData);
});
Now, I am trying to read the file as text (its a bad practice but wanted to find someway to make it work) but it doesn't throw any events. Can you please help me to find where I am going wrong ?
