select2 get selected option code example

Example 1: get select2 selected value

//initialize
$('#mySelect2').select2('data');
//get selected value
$('#mySelect2').find(':selected');

Example 2: select2 preselect option

$('#mySelect2').val('1'); // Select the option with a value of '1'
$('#mySelect2').trigger('change'); // Notify any JS components that the value changed

Example 3: select2 multi select get selected value

alert("Selected value is: "+$(".leaderMultiSelctdropdown").select2("val"));

alternatively, if you used a regular selectbox as base, you should be able to
use the normal jquery call, too:

alert("Selected value is: "+$(".leaderMultiSelctdropdown").val());

Example 4: select2

$('.js-example-basic-single').select2({
  placeholder: 'Select an option'
});
