Blob.formData

Read the data from the blob as a FormData object.

This first decodes the data from UTF-8, then parses it as a multipart/form-data body or a application/x-www-form-urlencoded body.

The type property of the blob is used to determine the format of the body.

This is a non-standard addition to the Blob API, to make it conform more closely to the BodyMixin API.

Referenced types

class FormData

Provides a way to easily construct a set of key/value pairs representing form fields and their values, which can then be easily sent using the XMLHttpRequest.send() method. It uses the same format a form would use if the encoding type were set to "multipart/form-data".
