This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
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.encodingRead only- 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.
