Hi

This works fine and adds a new element to the list:


document.forms['formname'].elements['listname'].options[0] = new
Option('foo', 'bar');


... but using the following code in a popup window - IE crashes or tells
me that the server threw an exception:


window.opener.document.forms['formname'].elements['listname'].options[0]
= new Option('foo', 'bar')


The code works just fine in Firefox. Could someone give me at hint on
what's wrong here?

Kind regards Søren

Probably that you are adding an instance of Option from the current
document to a select from another document. I would try using the "Option"
constructor function from the other window, i.e., something like:

var otherWindow = window.opener;
otherWindow.document.forms['formname'].elements['listname'].options[0] =
new otherWindow.Options('foo','bar');

Not sure whether it works, though. My tests are inconclusive


To avoid this cross-page DOM scripting, you could put a function on the
original page to do the work, and just call it from the opened page.

<script type="text/javascript">
function addOption(text,value) {
document.forms['formname'].elements['listname'].options[0] =
new Option(text,value);
}
</script>

and then just do
window.opener.addOption('foo','bar');
in the opened window.
