Hi there,

I'm working on a JavaScript function for a form.

My form is a survey with about four groups of radio buttons.

I want to create one function that I can return the value from one of the radio button groups by passing the name of the radio button group as a variable.

Here's a sample of the code to get the value of a radio group called "concerts"

function get_radio_value()
{
for (var i = 0; i < document.orderform.music.length; i++)

}

function get_radio_value( group ) /* For simplicity, assumes at least 2 buttons in group*/
{
  for (var i = 0; i < group.length && !group[i].checked; i++)
  ;

  return i==group.length ? "" : group[i].value;
}

get_radio_value(  document.orderform.music );

Thanks a lot. I'll give it a go!
