IDBFileHandle.readAsText()
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 readAsText()
method of the IDBFileHandle
interface
reads the content of the associated file
and provide the result of that reading as a string.
In many ways, it performs like the FileReader.readAsText()
method.
The reading operation starts at the position given by the
location
property.
Note: The three interfaces IDBMutableFile
, IDBFileHandle
, and IDBFileRequest
are deprecated and only implemented
for backward compatibility in Firefox. Do not use them anymore:
consider using the File and Directory Entries API instead.
