Hi All,
I'm trying to alter the contents of a drop-down (select) list on the
parent window from a child window in IE 6. After opening the child
window, I set its opener to reference the parent like this:
childwin = window.open(... )
if (childwin == null)
childwin.opener = self;
Then, to update the parent select list from the child window, I do
this:
opener.document .myForm.NameOfS elect.options.l ength = 0;
opener.document .myForm.NameOfS elect.options[0] = new Option("", "");
for (var ixy = 1; ixy <= newDataArray.le ngth; ixy++)
{
opener.document .myForm.NameOfS elect.options[ixy] = new
Option(someNewD isplayText, newValue);
}
This looks correct and works up to a point. I can empty the parent
select by setting the its options.length to zero. But, when I try to
add new options, IE gives me a "server threw an exception" message.
Is all this even possible in IE?
TIA.

The above code is suspicious. if(childwin==nu ll) the window wasn't opened
and your reference to childwin.opener and further assignment should at least
throw a fit if not an exception.
Then, to update the parent select list from the child window, I do
this:
opener.document .myForm.NameOfS elect.options.l ength = 0;
opener.document .myForm.NameOfS elect.options[0] = new Option("", "");

{
opener.document .myForm.NameOfS elect.options[ixy] = new
Option(someNewD isplayText, newValue);
}
looks OK. maybe window.opener is safer

Hi Jimbo,
You're exactly right! I had to set up a function on the parent window
for the child to call so that it could update the list on the parent.
Phew, that was a mouthful. Anyway, thanks for you suggestion.
