FileReader: readAsArrayBuffer() method
The FileReader
interface's
readAsArrayBuffer()
method is used to start reading the
contents of a specified Blob
or File
. When the read
operation is finished, the readyState
becomes
DONE
, and the loadend
is
triggered. At that time, the result
attribute
contains an ArrayBuffer
representing the file's data.
Note: The Blob.arrayBuffer()
method is a newer promise-based API to read a
file as an array buffer.
Syntax
js
readAsArrayBuffer(blob)
Parameters
Return value
