Enable text box when specific option is selected

[jschlosser]

I can enable a text box with an onChange if ANY option is selected
from a select list, but how do I do this for a specific selection?
Even better would be if the field didn't appear until after the
event. This is for those selecting "other" to tell us what "other"
is.

Thanks.

In the onchange event of the select element, examine which option is
currently selected with the selectedIndex property. Then (enable and
show) or (disable and hide) the text area using something like
textarea.disabled=true;textarea.style.display='non e';

Give it a try with a complete demo web page that is just 40 lines or
less. If you have troubles you can post that code which will give
people a way to help you better.
