This page has been flagged with the following issues:

High-level issues:


W3C Working Draft

Summary

Allows for synchronous reading of File or Blob objects. Only available in Workers, as synchronous I/O would otherwise block the main application from executing.


Properties

No properties.

Methods

No methods.

Events

No events.

Needs Examples: This section should include examples.

Notes

Important:  The FileReaderSync object's read methods (readAsText, readAsDataURL, and readAsArrayBuffer) have the same method signatures as the read methods of the FileReader object but they behave synchronously (as opposed to asynchronously).
