Element Description
WORadioButtonList displays a list of radio buttons. The user
may select one of the objects in the list, and this object is returned
as selection.
Synopsis
WORadioButtonList { list=anObjectList;
item=anIteratedObject; displayString=displayedValue; [value=aValue;]
[index=aNumber;] [prefix=prefixString;]
[suffix=suffixString;] [selection=selectedValue;]
[name=fieldName;] [disabled=aBoolean;]
[escapeHTML=aBoolean;]... };
Bindings
| You should provide the title of a radio button
in displayString rather than in value.
If there is no binding for displayString,
the string assigned to value is used as
the label of the button. |
- list
- Array of objects that the WORadioButtonList will iterate
through.
- item
- Current item in the list array. (This attribute's
value is updated with each iteration.)
- displayString
- String to display beside the radio button for the current
item.
- value
- Value for the
INPUT tag
of the current item (INPUT type="RadioButton"
value="someValue">.
- index
- Index of the current iteration of the WORadioButtonList.
- prefix
- An arbitrary HTML string inserted before each value.
- suffix
- An arbitrary HTML string inserted after each value.
- selection
- An object that the user chose from the list.
- name
- Name that uniquely identifies this element within the
form. You may specify a name or let WebObjects automatically assign
one at runtime.
- disabled
- If disabled evaluates to
true (or YES),
this element appears in the page but is not active.
- escapeHTML
- If escapeHTML evaluates to
true (or YES),
the string rendered by displayString is
converted so that characters which would be interpreted as HTML
control characters become their escaped equivalent (this is the
default). Thus, if a your displayString is
"a <b>bold</b> idea",
the string passed to the client browser would be "a
<B>bold</B> idea", but
it would display in the browser as "a <b>bold</b>
idea". If escapeHTML evaluates
to false (or NO),
WebObjects simply passes your data to the client browser "as is."
In this case, the above example would display in the client browser
as "a bold idea".
If you are certain that your strings have no characters in them
which might be interpreted as HTML control characters, you get better
performance if you set escapeHTML to false (or NO).
