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() constructor returns a newly created TextEncoder object for the encoding specified in parameter.
Syntax
encoder = new TextEncoder(utfLabel);
Parameters
- utfLabel
- Is a
DOMStringcontaining the label of the encoder. Each label is associated with a specific encoding type:Possible values of utfLabel Encoding " unicode-1-1-utf-8", "utf-8", "utf8"'utf-8'" utf-16be"'utf-16be'" utf-16", "utf-16le"'utf-16le'
Exceptions
RangeErroris thrown if utfLabel is not one of the supported values.
Example
var textEncoder = new TextEncoder("unicode-1-1-utf-8");

[1] An earlier, and slightly different, version of the specification was implemented in Gecko 18.
Before Gecko 38, an invalid parameter lead to a TypeError exception instead of the standard RangeError.
