The TextEncoder interface represents an encoder for a specific method, that is a specific character encoding, like utf-8, iso-8859-2, koi8, cp1261, gbk, ... An encoder takes a stream of code points as input and emits a stream of bytes. For a more scalable, non-native library, see StringView – a C-like representation of strings based on typed arrays.
Properties
The TextEncoder interface doesn't inherit any property.
TextEncoder.encoding只读- Is a
DOMStringcontaining the name of the encoder, that is a string describing the method theTextEncoderwill use.
Constructor
TextEncoder()- Returns a newly constructed
TextEncoderthat will generate a byte stream with the encoding method specified in parameters.
Methods
The TextEncoder interface doesn't inherit any method.
TextEncoder.encode()- Returns a
Uint8Arraycontaining the text encoded with the method for this specificTextEncoderobject.
