What is "formdata"

FormData is an interface that is part of the Xmlhttprequest Level 2. The browsers with XHR2 support make the manufacturer available FormData so that such an object can be created and used via javascript. This object represents the data of a form to be submitted via XHR2, including files for upload and blobs binaries.
