readAsText method

void readAsText(
  1. Blob blob, [
  2. String encoding
])

The readAsText() method of the FileReader interface is used to read the contents of the specified Blob or File. When the read operation is complete, the FileReader.readyState property is changed to DONE, the FileReader.loadend_event event is triggered, and the FileReader.result property contains the contents of the file as a text string.

Note: The Blob.text method is a newer promise-based API to read a file as text.

Note: This method loads the entire file's content into memory and is not suitable for large files. Prefer FileReader.readAsArrayBuffer for large files.

Implementation

external void readAsText(
  Blob blob, [
  String encoding,
]);
