FormData

From WHATWG Wiki
Jump to: navigation, search

Defining the FormData format (multipart/form-data).

Each entry either has

Content-Disposition: form-data; name="..."

or

Content-Disposition: form-data; name="..."; filename="..."
Content-Type: ...

Issues:

  • The HTML dirname feature seems to be one way only. Maybe the feature needs to be redesigned?
  • If there is no name, imply "isindex"?
  • Encoding: name appears to consist of bytes (per encoding of form)

HTML Idea

Something like HTMLFormElement.populate(FormData) which updates all entries with the data from FormData. Maybe it should take a dictionary to indicate whether unaffected items should be cleared or retained.

History

Initially this page was about evolving the FormData API. That has long since happened.
