Custom JavaScript examples

[baggins]

In the firmware starting from 4.2016 there is Custom JavaScript feature available in LogicMachine --> Scripting --> Tools --> Edit custom JavaScript. 
It is possible to create different dynamic tasks, like detect short/long press from visualization using one icon (Erwin, will you please add your example here) or as in this example, we can open specific Floor/Plan when some grp address is triggered - useful e.g. when you want IP Camera page automatically to be opened when Intercom button is pressed:

Code:

$(function(){
 if (typeof objectStore !== 'undefined') {
   var id = Scada.encodeGroupAddress('1/1/2');

   objectStore.addListener(id, function(object, type) {
     if (type == 'value') {
       showPlan(69);
     }
   });
 }
});

showPlan() value can be get when you hover your mouse over specific plan name and click on the arrow. Please see in pictures attached.

Hi,
I have two addresses, say '1/1/2' and '1/1/3' that I want to use to trigger the same showPlan. I have absolutely no knowledge of javascript, so how do I modify this code?
Is my understanding correct that this code gets executed whenever any address is triggered?

Thanks.
