I am using the animation extender in asp.net ajax and have a RadioButtonList
in a div and access it in javascript through the extender.

The object passed into the javascript function is definitely the
RadioButtonList but I can not seem to get to the selectIndex property.

When I do a Object.id it does however give me the correct name of the
RadioButtonList id name.

Just not sure of the syntax to get at the selectIndex property

thanks

a radiolist is just a span or table (depending on style) with radio
buttons in it. the id refers to the span/table, not the buttons. to get
the selected index, you get the span/table by id, walk its children
nodes (may need to recurse) looking for radio buttons (tagname=="INPUT"
type=="radio"). count the buttons until you find a checked one. that is
the index. to get the value instead of the index (more useful in
javascript) get the value of the checked one.
