My code for this (written probably five years ago) looks very similar, but
maybe two versions would help...
function locateDDValue(drop_down, find_me) {
found_it = false;
for (i = 0; (i < drop_down.length) && !found_it; i++) {
if (drop_down.options[i].value == find_me) {
found_it = true;
drop_down.options[i].selected = true;
}
}
return found;
}
Has the minor benefit of telling the caller whether the value was found or
not. Also, not that this is case-sensitive, so you may want to do some
toLowerCase() calls on find_me and each value checked against from the
dropdown.
