DESCRIPTION
Rose::HTML::Form::Field::Numeric is a subclass of Rose::HTML::Form::Field::Text that only accepts numeric values. It overrides the validate() method of its parent class, returning true if the internal_value() is a valid number, or setting an error message and returning false otherwise.Use the min and :<max|/max> attributes to control whether the range of valid values.
OBJECT METHODS
- max [NUMERIC]
- Get or set the maximum acceptable value. If the field's internal_value() is greater than this value, then the validate() method will return false. If undefined, then no limit on the maximum value is enforced.
- min [NUMERIC]
- Get or set the minimum acceptable value. If the field's internal_value() is less than this value, then the validate() method will return false. If undefined, then no limit on the minimum value is enforced.
- negative [BOOL]
- If BOOL is true or omitted, sets max to 0. If BOOL is false, sets max to undef.
- positive [BOOL]
- If BOOL is true or omitted, sets min to 0. If BOOL is false, sets min to undef.
