CONSTRUCTOR ^

new PARAMS

Constructs a new Rose::HTML::Form::Field::RadioButton object based on PARAMS, where PARAMS are name/value pairs. Any object method is a valid parameter name.

OBJECT METHODS ^

checked [BOOL]

Check or uncheck the radio button by passing a boolean value. If BOOL is true, the radio button will be checked. If it is false, it will be unchecked. Returns true if the radio button is checked, false otherwise.

hidden [BOOL]

Get or set a boolean value that indicates whether or not this radio button will be shown in its parent radio button group. Setting it to true also sets checked to false.

hide

Calls hidden, passing a true value.

html_radio_button

Returns the HTML serialization of the radio button field only (i.e., without any label or error message)

is_checked

Returns true if the radio button is checked, false otherwise.

is_on

Simply calls is_checked(). This method exists for API uniformity between radio buttons and checkboxes.

show

Calls hidden, passing a false value.

value [VALUE]

Gets or sets the value of the "value" HTML attribute.

xhtml_radio_button

Returns the XHTML serialization of the radio button field only (i.e., without any label or error message)
