LockedFile.active - 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.

The active property allows to know if the LockedFile object is still usable (true) or not (false). If the object is inactive then it is impossible to perform any read or write operation with it. Typically, a LockedFile object becomes inactive when the LockedFile.abort() method is called or if an error occurs.

Syntax

var state = instanceOfLockedFile.active

Value
