How to Detect Clicked Event Handler on Select2 Element in Jquery?

Question

I tried to detect if the clicked element is select2 and perform additional action as required not just opening dropdown list. But it is not successful as I clicked on select2 element nothing happened.

$(document).ready(function() {
  $('select').select2();

  $('body').on('click', function(e) {
    if ($(this).data('select2')) {
      console.log('select2 element was just clicked');
    } else {
      console.log('you are not clicking on select2');
    }
  });

})

I don't know why select2 does not receive clicked event. Is there any workaround solution archive this because I need to do more action when select2 was clicked? Thanks so much.

You should probably use one of the events the plugin provides, instead of trying to interfere with it from the outside. https://select2.org/programmatic-control/events — 04FS, Feb 06 '19 at 11:01
try $('select').select2().on() events , http://select2.github.io/select2/ — John Rajan, Feb 06 '19 at 11:08
@04FS, thanks, but from provided event does not include clicked event handler. For some reasons, select2 element on device does not open on a single click, therefore, I tried to make it works, open, by make it open on click event on it. — Houy Narun, Feb 06 '19 at 11:08
That’s the wrong “therefore” here - you should rather investigate what causes the problem and then fix it, instead of trying to add workarounds. — 04FS, Feb 06 '19 at 11:10

How about something like this? here's another example: https://jsfiddle.net/f8q2by55/ http://jsfiddle.net/6jaodjzq/

as stated in this answer: Attach click-event to element in .select2-result

Because Select2 lib prevents any click events on popover list you can't bind events to .info directly. But you can redefine onSelect method and place there any code you want.

$(document).ready(function() {
  let selector = $('#select').select2()
     selector.onSelect = (function(fn) {
        return function(data, options) {
            console.log('selected');
        }
    })(selector.onSelect);
})

basically without massive editing, you cannot add `on click` event to select2 js item, you only can easily access `onSelect ` — bestestefan, Feb 06 '19 at 11:26
