readAsArrayBuffer method

void readAsArrayBuffer(
  1. Blob blob
)

The readAsArrayBuffer() method of the FileReader interface is used to start reading the contents of a specified Blob or File. When the read operation is finished, the FileReader.readyState property becomes DONE, and the FileReader.loadend_event event is triggered. At that time, the FileReader.result property 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.

Implementation

external void readAsArrayBuffer(Blob blob);
