FormData()
-
Creates a new
FormData
object.
The FormData
interface provides a way to construct a set of key/value pairs representing form fields and their values, which can be sent using the navigator.sendBeacon()
methods. It uses the same format a form would use if the encoding type were set to "multipart/form-data"
.
You can also pass it directly to the <form>
would do if it were using simple GET
submission.
An object implementing FormData
can directly be used in a entries()
: for (const p of myFormData)
is equivalent to for (const p of myFormData.entries())
.
