Rails spinoffs - Oct 2006 - optgroup and Javascript Issues

Is there a way to walk a select box that has multiple enabled and a few
optgroup mixed in with other groups?

The following seems to work without the optgroup tags in a multiselect
list box.  I have tired going threw the children of the optgroup but i
was unable to pull a valid .value or .selected.

Any Ideas?  Thanks.

var objGroups = document.getElementById(''groups'').childNodes;
var aSelectedGroups = new Array();

for (var i = 0; i < objGroups.length; i++) {
	if (objGroups[i].selected == true) {
		aSelectedGroups.push(objGroups[i].value);
	}
}

I''m not sure I get this.  Don''t the
HTMLSelectElement''s properties work
for you?  Can''t you just walk the options collection and test the
selected attribute?

Better yet, doesn''t Prototype''s $F function work properly on
your
<select> element?
