Constructs a new instance of the FieldTextInput class


constructor(value?: string | typeof Field.SKIP_SETUP, validator?: FieldTextInputValidator | null, config?: FieldTextInputConfig);


Parameter Type Description
value string | typeof Field.SKIP_SETUP (Optional) The initial value 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 FieldTextInputValidator | null (Optional) A function that is called to validate changes to the field's value. Takes in a string & returns a validated string, or null to abort the change.
config FieldTextInputConfig (Optional) A map of options used to configure the field. See the [field creation documentation] for a list of properties this parameter supports.
