I need Dojo/JavaScript help. I would like to use the Dojo AJAX
framework to populate two ComboBoxes.  I get the first box populated,
but I need to know how to (dynamically) populate the second based on
the choice made on the first.

Here is some code:

<!--********************-->
<form id="vcdb">

	<!-- Present Year options | 2006, 2005, 2005, Et Cetera -->
	<select dojoType="ComboBox" value="this should never be seen - it is replaced!"
		dataUrl="http://localhost/test/ajax/vcdb.asp" style="width: 300px;"
name="foobar1" maxListLength="15">
	</select>
	
	<br>
	
	<!-- Present Make options available | Ford, Chevy, Et cetera --> 
	<select dojoType="ComboBox" value="this should never be seen - it is replaced!"
		dataUrl="http://localhost/test/ajax/vcdb.asp?year={Current value of
foobar1}" style="width: 300px;" name="foobar2" maxListLength="15">
	</select>
	
</form>
<!--********************-->

The first ComboBox works fine; However, I don't know how to
call/populate the second.  How do I write {Current value of foobar1}
in JavaScript that Dojo understands?

Thanks.

Why not try it with several comboboxes, but only displaying the one
which is determined by the value of the first one?
