FileRequest - Web APIs 编辑

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 is in progress.

The FileRequest interface also inherits from the DOMRequest interface.
