I would believe you would just have to reverse your search order to start
from high and go low... Instead of low to high
for (iLow = 0; iHigh = iLow; iLow++){
// Get the current option
sTemp = oOptions(iCurrent).value.toUpperCase();
var sSubstr = sTemp.substr(0, iLength);
if (sSubstr < sInput)
{
// Search the upper half of the branch
iLow = iCurrent + 1;
}
else if (sSubstr > sInput)
{
// Search the lower half of the branch
iHigh = iCurrent - 1;
}
else
{
bFound = true;
break;
}
// Pick the middle of the branch again
iCurrent = Math.floor(iLow + ((iHigh + 1) - iLow) / 2);
}
I hate editing other peoples crap so I think im completely wrong cause I
don't feel like analyzing this junk. But the basic jist would be to revers
the order in which the list is gone through.
Hope that helps at all.... ^_^;

Subject: OT- java problem
I was asked recently to edit a ASP page that generates the following HTML so
that the drop down was in descending order. I did that. It was as simple
as editing the SQL statement. Now a piece of Java code that was working to
allow the user to type in box A to select an item in the dropdown is not
working. If I revert the dropdown to the original ascending sort order it
works fine again. Is there anyone out there that might like to help with
this? Below is the entire original html document.
Html to follow - watch for wrap.
