Trigger an action after selection select2

Question

I am using select2 library for my search.
is there any way to trigger an action after selecting a search result? e.g. open a popup, or a simple js alert.

Answer 1

As per my usage above v.4 this gonna work

$('#selectID').on("select2:select", function(e) { 
    //var value = e.params.data;  Using {id,text format}
});

And for less then v.4 this gonna work:

$('#selectID').on("change", function(e) { 
   //var value = e.params.data; Using {id,text} format
});
