Comment (by illogical):
The line
{{{
box.options.length = 0; // clear all options
}}}
takes several seconds to complete with just about 2.5k entries in the
select box on IE9, other IE versions seem to be affected as well.
Right now I don't have time for this, but maybe I can provide some test
results later on.
It seems to perform way better when I replace this with
{{{
while (box.hasChildNodes()) {
box.removeChild(element.firstChild());
}
}}}
which also seems much more sane to me.
Another way might be to set innerHTML to "".
