new TextDecoder([encoding[, options]])


  • encoding <string> 标识此 TextDecoder 实例支持的 encoding默认值: 'utf-8'
  • options <Object>
    • fatal <boolean> 如果解码失败是致命的,则为 true默认值: false
    • ignoreBOM <boolean>true 时,TextDecoder 将在解码结果中包含字节顺序标记。 当 false 时,字节顺序标记将从输出中删除。 此选项仅在 encoding'utf-8''utf-16be''utf-16le' 时使用。 默认值: false

创建新的 TextDecoder 实例。 encoding 可以指定支持的编码之一或别名。

TextDecoder 类也在全局对象上可用。

  • encoding <string> Identifies the encoding that this TextDecoder instance supports. Default: 'utf-8'.
  • options <Object>
    • fatal <boolean> true if decoding failures are fatal. This option is only supported when ICU is enabled (see Internationalization). Default: false.
    • ignoreBOM <boolean> When true, the TextDecoder will include the byte order mark in the decoded result. When false, the byte order mark will be removed from the output. This option is only used when encoding is 'utf-8', 'utf-16be' or 'utf-16le'. Default: false.

Creates an new TextDecoder instance. The encoding may specify one of the supported encodings or an alias.

The TextDecoder class is also available on the global object.
