[Active4d-dev] Toggling field visibility on a form

[Brad Perkins]

Apologies if this isn't the best forum for this. I've looked at various 
sites on the web and basically found many poor examples.

In an A4D served web site I have a form with a select menu. The last item 
in this menu is "Other..." If the user selects that item I want to display 
an entry field where they can enter another value. If they selects any 
other item I want to hide (or disable) the "other" entry field. As an 
alternate strategy I'd consider popping up a small form window with an 
entry field in it that upon completion would update the select menu with 
the new value.

Does anyone have any tested cross-platform javascript code that 
accomplishes this?

Thanks,
Brad
