jquery - Trigger an action after selection select2 -

i using select2 library search.
there way trigger action after selecting search result? e.g. open popup, or simple js alert.

$("#e6").select2({     placeholder: "enter item id please",     minimuminputlength: 1,     ajax: { // instead of writing function execute request use select2's convenient helper         url: "index.php?r=sia/searchresults",         datatype: 'jsonp',         quietmillis: 3000,         data: function (term, page) {         return {             q: term, // search term             page_limit: 10,             id: 10             };         },         results: function (data, page) { // parse results format expected select2.             // since using custom formatting functions not need alter remote json data             return {results: data};         },     },      formatresult: movieformatresult, // omitted brevity, see source of page     formatselection: movieformatselection, // omitted brevity, see source of page     dropdowncssclass: "bigdrop", // apply css makes dropdown taller     escapemarkup: function (m) { return m; } // not want escape markup since displaying html in results }); 

see events section in documentation or further details section on events.

depending on version, 1 of snippets below should give event want, alternatively replace "select2-selecting" "change".

version 4.0 +

events in format: select2:selecting (instead of select2-selecting)

thanks snakey notification has changed of 4.0

$('#yourselect').on("select2:selecting", function(e) {     // happen }); 

version before 4.0

$('#yourselect').on("select2-selecting", function(e) {     // happen }); 

just clarify, documentation select2-selecting reads:

select2-selecting fired when choice being selected in dropdown, before modification has been made selection. event used allow user reject selection calling event.preventdefault()

whereas change has:

change fired when selection changed.

so change may more appropriate needs, depending on whether want selection complete , event, or potentially block change.
