Select2 multiple not getting html selected options using jQuery

Question

I am struggling trying to get from my select2 multiple dropdown the html of selected options.

Here my case.

1. I have this standard select2-multiple:

2. Now I change selection of users, but in console it is not able to take them using jQuery. The code to identify the selected options from dropdown is:

   .select2-results__option[aria-selected=true]

So it should be found using this:

var selected_users = $('.select2-results__options').find('li .select2-results__option[aria-selected=true]').html();
  $('.stakeholders_span').html(selected_users);
  console.log(selected_users);

Console log gives always "undefined".

Anyone able to help me :)?

Thanks!

Problem is Space in selector after the li, should be like

'li.select2-results__option[aria-selected=true]').html();
  $('.stakeholders_span'

$(document).ready(function() {
    $('.select2-results').select2({templateResult: formatState});
    
    $('.select2-results').on("select2:open", function (e) {                   console.log("open dropdown"); 

      var selected_users = $('.select2-results__options').find('li.select2-results__option[aria-selected=true]');
      $("#selected").html(selected_users);
      console.log(selected_users.length+" already selected"); 
    });
    
    
    function formatState (state) {
      var img_url = ($(state.element).attr("url"));
      if (!state.id) { return state.text; }
      var $state = $(
       '<span ><img sytle="display: inline-block;" src="'+img_url+'" /> ' + state.text + '</span>'
      );
      return $state;
     }
});

select{

width:100%;

}

------------
<div id="selected"></div>

Answer 2

I still have the issue.

This is the starting point:

This is the select2 opened when I add a third user:

And this is what I see: only the latest new added:

While I should see the three users.

I applied this code, but is shows only the latest added user:

      var stakeholders = $('.select2-results__options').find('li.select2-results__option[aria-selected=true]').html();
  console.log(stakeholders);
  $('.stakeholders_span').html(stakeholders);

How to solve the above?
