I've got what should be a simple assignment of either an element value
or a default string to a variable, but when the element doesn't exist I
get an "Object required" error rather than an assignment of the default
value.
I originally used the simple statement:
var v = document.getElementById('foo').value ||
parent.document.getElementById('foo').value ||
'unknown';

Hello,
I'm trying to get the value out of a dropdown list box and
assign it to a variable. When I click on the list box, I
invoke this line of code. I get the error, "Object
reference not set to an instance of an object".
The same list box is referenced successfully in the form
load. Does anyone know what might cause this problem?
