(append this & args)
Method.
The append() method of the web.other.FormData
interface appends
new value onto an existing key inside a FormData object, or adds
key if it does not already exist.
`There are two versions of this method: a two and a three parameter version:
formData.append(name, value); formData.append(name, value, filename);`

(constructor & args)
Constructor.
The FormData() constructor creates a new web.other.FormData
object.
form Optional
An HTML <form>
element — when specified, the web.other.FormData
object will be populated with the form's current keys/values using the name property of each element for the keys and their submitted value for the values. It will also encode file input content.

Parameters
name
The name of the field whose data is contained in value.
value
The field's value. In the two parameter version this is a web.USVString
, or if it is not, it is converted to a string. In the three parameter version this can be a web.files.Blob
, web.files.File
, or a web.USVString
. If none of these are specified the value is converted to a string.
filename Optional
