Hi to all,
A probably stupid question...how can I use the setup tab in a function Node?
I need to set the Var i = 0 for the first time that the function node is called, and then go on with the code written in the function tab.
Is there a special syntax to put in the setup tab?
Thanks to all
Hi @LucaCarminati
Each of the setup
, function
and close
functions run in their own scope. Any variables you declare in one are only visible in that one.
This is where you can use the context
object - which is shared between the functions.
In this instance you'd do:
context.set('i',0);
in the setup
tab, and then:
var i = context.get('i');
in the main function
.

Hi @knolleary ,
Thanks a lot!
I have used yet the context var until now, and I thought that the Setup tab could be used for the initial setup of the variables (without using the context); I will use your solution.
Thanks again!
