Now, I want to retrieve the selecte

    The correct way to do this as of v4 is:

    $('.select2-chosen').select2('data')[0].text

    It is undocumented so could break in the future without warning.

    You will probably want to check if there is a selection first however:

    var s = $('.select2-chosen');
    
    if(s.select2('data') && !!s.select2('data')[0]){
        //do work
    }

    Again I suggest Simple and Easy

    Its Working Perfect with ajax when user search and select it saves the selected information via ajax

     $("#vendor-brands").select2({
       ajax: {
       url:site_url('general/get_brand_ajax_json'),
      dataType: 'json',
      delay: 250,
      data: function (params) {
      return {
        q: params.term, // search term
        page: params.page
      };
    },
    processResults: function (data, params) {
      // parse the results into the format expected by Select2
      // since we are using custom formatting functions we do not need to
      // alter the remote JSON data, except to indicate that infinite
      // scrolling can be used
      params.page = params.page || 1;
    
      return {
        results: data,
        pagination: {
          more: (params.page * 30) < data.total_count
        }
      };
    },
    cache: true
    },
    escapeMarkup: function (markup) { return markup; }, // let our custom    formatter work
    minimumInputLength: 1,
    }).on("change", function(e) {
    
    
      var lastValue = $("#vendor-brands option:last-child").val();
      var lastText = $("#vendor-brands option:last-child").text();
    
      alert(lastValue+' '+lastText);
     });

    Used this for show text

    var data = $('#id-selected-input').select2('data'); 
    data.forEach(function (item) { 
        alert(item.text); 
    })

    As of Select2 4.x, it always returns an array, even for non-multi select lists.

    var data = $('your-original-element').select2('data')
    alert(data[0].text);
    alert(data[0].id);
    

    For Select2 3.x and lower

    Single select:

    var data = $('your-original-element').select2('data');
    if(data) {
      alert(data.text);
    }
    

    Note that when there is no selection, the variable 'data' will be null.

    Multi select:

    var data = $('your-original-element').select2('data')
    alert(data[0].text);
    alert(data[0].id);
    alert(data[1].text);
    alert(data[1].id);
    

    From the 3.x docs:

    data Gets or sets the selection. Analogous to val method, but works with objects instead of ids.

    data method invoked on a single-select with an unset value will return null, while a data method invoked on an empty multi-select will return [].

    I finally figured it out doing this:

    var $your-original-element = $('.your-original-element');
    var data = $your-original-element.select2('data')[0]['text'];
    alert(data);
    

    if you also want the value:

    var value = $your-original-element.select2('data')[0]['id'];
    alert(value);

    In Select2 version 4 each option has the same properties of the objects in the list;

    if you have the object

    Obj = {
      name: "Alberas",
      description: "developer",
      birthDate: "01/01/1990"
    }
    

    then you retrieve the selected data

    var data = $('#id-selected-input').select2('data');
    console.log(data[0].name);
    console.log(data[0].description);
    console.log(data[0].birthDate);
