File. When the read operation is finished, the
DONE, and the
loadend is triggered. At that time, the
result attribute contains an
ArrayBuffer representing the file's data.
The definition of 'FileReader.readAsArrayBuffer' in that specification.

 Prior to Gecko 2.0 beta 7 (Firefox 4.0 beta 7), all
Blob parameters below were
File parameters; this has since been updated to match the specification correctly. Prior to Gecko 13.0 (Firefox 13.0 / Thunderbird 13.0 / SeaMonkey 2.10) the
FileReader.error property returned a
FileError object. This interface has been removed and
FileReader.error is now returning the
DOMError object as defined in the latest FileAPI draft.
 IE9 has a File API Lab.
 Opera has partial support in 11.1.
