insert item to dropdownlist using javascript

[Joe Fallon]

I can add items to my dropdown list using javascript like this:

cbo.length = j+2;

cbo.options[j].text = "Some Text";

cbo.options[j].value = "MyValue";

cbo.options[j+1].text = "Some Other Text";

cbo.options[j+1].value = "MyOtherValue";

But the above code adds them to the bottom of the list.

My question is how can add them back at a specific index in the list?
(I have a list of 10 items but remove two if they click an option button. If
they click back to the original value of the option group I want to add the
2 values back to the list. But in the right place.)

Any ideas?

Joe,

First, remember the original index for the removed items.

Second, increment the ddl list by 2, as you do.

Third, move all options starting from the original position 2 positions up.
Do it in reverse order, starting from the highest position.

Forth, copy 2 removed item back to the original position.

Elihayu,
Thanks for the tip.
I thought it might have to be something along those lines.

FYI - what I ended up doing was making a copy of the original list and then
using it to overwrite the modified list if they decided to change back. The
copy is only created once so they can toggle as many times as they want.
Seems to work fine.

Thanks again.
