Programmatically Select Option

[J1C]

If I only know the value of an option is a select list, is it possible
to programmatically select that option?

I would be returning the value from a server-side script ...

How are you returning it? If you're sending the whole page,
just give that option tag the SELECTED attribute.

Loop through the options in the select. When you find one with the
required value, set its selected property to true.
function selectOpt( f, s, v ){
var opts = document.forms[f].elements[s].options;
var o, i = opts.length;
while ( ( o == opts[--i] ) ) {
if ( o.value == v ) {
o.selected = true;
return;
}
}
}

If it's a multiple select, drop the return.

Agghh...

while ( ( o = opts[--i] ) ) {
...
