This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
Draft
This page is not complete.
The formData() method of the Body mixin takes a Response stream and reads it to completion. It returns a promise that resolves with a FormData object.
Note: This is mainly relevant to service workers. If a user submits a form and a service worker intercepts the request, you could for example call formData() on it to obtain a key-value map, modify some fields, then send the form onwards to the server (or use it locally.)
Syntax
response.formData().then(function(formdata) {
// do something with your formdata
});
Parameters
None.
Returns
A promise that resolves with a FormData object.
Example
TBD.
