Well - you first asked how you can set the selected index when
generating the options list. And this would be one solution.

If you need to change the index afterwards - then use the selectedIndex
property.

However - you can also use the DOM to create a new select element with
options as well and *then* using selectedIndex afterwards would work
fine as well.

As an example on how to manipulate the DOM: I did this on my own website
to generate a dynamic chart on the fly:

See the source for how the generic placeholder gets replaced by the
chart canvas if the browser is able to support canvas elements at all.

Well - problem solved ;-)
