How To > How to use one script for several buttons

You want to have a set of buttons that should basically perform a similar action, but a bit different depending on which of the buttons has been pressed.

•Create some buttons

•Create a variable "button_id"

•On the OnPress event of each button, set the variable button_id to a certain value (e.g. on button 1 to 1, on button 2 to 2 and so on)

•Create one JavaScript

•Put the script file on the OnRelease event of each button

•In the script use a switch-case statement to differentiate what should happen with which button

New since version 2019 of the OPUS Projektor:

We have a function called GetCallerID now which tells you in a script from which object the script was executed. So alternatively to the solution above this function could be used in a generic script to find out which button was being pressed.
