Constructs a new instance of the FieldMultilineInput class


constructor(value?: string | typeof Field.SKIP_SETUP, validator?: FieldMultilineInputValidator, config?: FieldMultilineInputConfig);


Parameter Type Description
value string | typeof Field.SKIP_SETUP (Optional) The initial content of the field. Should cast to a string. Defaults to an empty string if null or undefined. Also accepts Field.SKIP_SETUP if you wish to skip setup (only used by subclasses that want to handle configuration and setting the field value after their own constructors have run).
validator FieldMultilineInputValidator (Optional) An optional function that is called to validate any constraints on what the user entered. Takes the new text as an argument and returns either the accepted text, a replacement text, or null to abort the change.
config FieldMultilineInputConfig (Optional) A map of options used to configure the field. See the [field creation documentation] for a list of properties this parameter supports.
