Element Description
WORadioButton represents itself as an on-off switch. Radio
buttons are normally grouped, since the most important aspect of
their behavior is that they allow the user to select no more than
one of several choices. If the user selects one button, the previously
selected button (if any) becomes deselected.
Since radio buttons normally appear as a group, WORadioButton
is commonly found within a WORepetition.
Alternatively, you can use the WORadioButtonList element.
Synopsis
WORadioButton {value=defaultValue;
[selection=selectedValue;] [name=fieldName;] [disabled=aBoolean;]
... };
WORadioButton {checked=aBoolean;
[name=fieldName;] [disabled=aBoolean;]
... };
Bindings
| in a WORadioButton declaration you must supply
either checked or value,
but not both: they are mutually exclusive. |
- value
- Value of this input element. If not specified, WebObjects
provides a default value.
- selection
- If selection and value are
equal when the page is generated, the radio button is selected. When
the page is submitted, selection is assigned
the value of the radio button.
- checked
- During page generation, if checked evaluates
to
true (or YES),
the radio button appears in the selected state. During request handling, checked reflects
the state the user left the radio button in: true (or YES)
if checked; false (or NO)
if not.
- name
- Name that identifies the radio button's group. Only
one radio button at a time can be selected within a group.
- disabled
- If disabled evaluates to
true (or YES),
this element appears in the page but is not active. That is, selection does
not contain the user's selection when the page is submitted.
