Question

Based in this article http://cloudevils.wordpress.com/2012/10/18/ajax-file-upload-without-post-using-html5/ I created a form to upload files. Initially works fine in chrome but now is not workin more. In FF work fine.
I made some debugs and this line

var bb = new (window.MozBlobBuilder || window.WebKitBlobBuilder || window.BlobBuilder)();

seems stop working in chrome.
Browsering around I find some info about BlobBuilder() function that is not supported more in chrome.

Can help me?

It’s gone or deprecated. Use the new Blob constructor.

In your tutorial instead of:

var bb = new (window.MozBlobBuilder || window.WebKitBlobBuilder || window.BlobBuilder)();
bb.append(data);
var blob = bb.getBlob();

Do:

var blob = new Blob([data]);
