Ideas around changing the FormData API.
Defining the FormData format (multipart/form-data).


* Populate FormData from the server. (multipart/form-data entity -> FormData)
Each entry either has
* Get and manipulate FormData values.


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


* void append(name, value [, filename]) — normalize Blob [+ filename] to File since it always gets a filename
or
* void set(name, value [, filename]) — replaces *all* name entries
* void remove(name) — removes *all* name entries
* sequence<DOMString> getNames()
* sequence<DOMString> getValues(name)


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


responseType = "formdata"
Issues:


Parse as multipart/form-data and populate FormData. Probably need to have a good definition of multipart/form-data first.
* 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 Proposal==
==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.

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.
