readAsBinaryString method

void readAsBinaryString(
  1. Blob blob
)

Note: This method is deprecated in favor of FileReader.readAsArrayBuffer.

The readAsBinaryString() method of the FileReader interface is used to start reading the contents of the 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 the raw binary data from the file.

Note that this method was once removed from the File API specification, but re-introduced for backward compatibility. Using FileReader.readAsArrayBuffer is recommended.

Implementation

external void readAsBinaryString(Blob blob);
