FileRequest
Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
Summary
The FileRequest
interface extends the DOMRequest
interface to provide some extra properties necessary for the LockedFile
objects.
Properties
FileRequest.lockedFile
Read only- The
LockedFile
object from which the request was started. FileRequest.onprogress
- A callback handler called repeatedly while the operation represented by the
FileRequest

The FileRequest
interface also inherits from the DOMRequest
interface.

DOMRequest
is completed. DOMRequest.onerror
