[Javascript] splice

[Chris Basken]

Did something happen to the splice function between IE 5 and 6?  I was digging
through an old page in my archives and I decided to make use of a snippet of
script, but when I try it now I get an unsupported error.

 for (var righti = 0; righti < aForm.dynamicList1.options.length; righti++) {
  if (aForm.dynamicList1.options[righti].selected == true) {
   aForm.dynamicList1.splice(righti,1);
  }
 }

It seems to be complaining about my use of splice, but I don't recall this
throwing an error before.  Am I missing something here?

aForm is just the name of the form in question and dynamicList1 is just a
select list.
