Can you use a variable name as the index of an array? It doesn't appear
so or I'm doing something wrong. Here's what I'm trying:
put 1 into tasks["Search"]
put 2 into tasks["Reports"]
then in a menuPick handler:
on menuPick pChoice
goto cd tasks[pChoice]
end menuPick
I need to do this because I have more cards than I have menu choices and
they are intermixed with the "real" ones and I don't want the user to go
directly to these "hidden" cards.
Variables will work. Besides the "goto" issue, where are you filling the
array? If it's in the same script as the menupick handler then it needs
to be declared as a script local variable at the top of the script:
local tasks -- allows all handlers in this script to access it
on fillArray
put 1 into tasks["Search"]
put 2 into tasks["Reports"]
end fillArray
on menuPick pChoice
if the keys of tasks = "" then fillArray
go to cd tasks[pChoice]
end menuPick
Otherwise it won't be shared among the script handlers. If you are
filling the tasks array in a different script, then you either need to
make it a global variable or store it in a custom property (or property
set) which you load into the tasks variable when you need it. In other
words, there must be some way for all handlers to get access to the
tasks variable. When it is only referenced within a handler, the
variable will be set to empty when the handler begins and deleted when
the handler ends.
If your stack design allows it, it's often easier to just name cards the
same as the menu items. Since card names aren't visible to the user, you
can call them anything, and then all you need to do is:
on menuPick pChoice
go cd pChoice
end menuPick
It's a good idea to set the navigationArrows property to false if you
don't want users paging through cards via the keyboard.
