TextDecoder()
The TextDecoder()
constructor returns a newly created TextDecoder
object for the encoding specified in parameter.
If the value for utfLabel is unknown, or is one of the two values leading to a 'replacement'
decoding algorithm ( "iso-2022-cn
" or "iso-2022-cn-ext
"), a DOMException
with the "TypeError"
value is thrown.
Syntax
decoder = new TextDecoder(utfLabel, options);
Parameters
-
utfLabel

Is a
DOMString
, defaulting to"utf-8"

-
A
Boolean

.
